PHOENIX – New ramps connecting Loop 303 and Grand Avenue (US 60) in Surprise will open to traffic this weekend, a key milestone for the project to improve the interchange that links the two roadways.

The northbound Loop 303 on- and off-ramps and southbound Loop 303 on-ramp at Grand Avenue are scheduled to open by 11:30 p.m. Friday (April 1), according to the Arizona Department of Transportation.

Prior to opening the ramps to traffic, Loop 303 and current connections with Grand Avenue will be temporarily closed at approximately 10 p.m. Friday. The temporary traffic signals on the Loop 303 bridge over Grand Avenue will be turned off and the ramps will be prepared to open to traffic.

A ramp that currently handles all Grand Avenue connections will be reconfigured over the weekend to connect southbound Loop 303 to Grand Avenue by 5 a.m. Monday (April 4). Drivers on southbound Loop 303 who want to exit at Grand Avenue this weekend can travel south to the Bell Road exit. From there they can turn and use northbound Loop 303 to exit at Grand Avenue.

The entire $46 million Loop 303/Grand Avenue Interchange improvement project is scheduled for completion this summer.

SURPRISE ‒ Next weekend, Grand Avenue (US 60) will be closed from 9 p.m. March 18, to 7 p.m. March 20, between R.H. Johnson Boulevard/Sunrise Boulevard and Loop 303 to accommodate freeway bridge work, according to the Arizona Department of Transportation.

Motorists should plan ahead and consider alternate routes while the closure is in effect.

The primary detour for Grand Avenue traffic will be along Loop 303 and Bell Road. Southbound Loop 303 drivers in the Peoria area can connect with Grand Avenue via southbound El Mirage Road and westbound Bell Road.

Depending on their destination, motorists heading southeast on US 60 may want to consider eastbound State Route 74 to southbound Lake Pleasant Parkway or southbound I-17.

Traffic on Loop 303 won’t be affected by the Grand Avenue closure.

Crews will be painting the bridge and installing sound panels and signage at the Loop 303/Grand Avenue interchange as part of a $46 million ADOT project scheduled for completion this summer.

Ramps built during the first phase of the Loop 303/I-10 traffic interchange project will be completed in the second phase.

If you drive in the West Valley, you might have noticed some ramps near the Loop 303/I-10 interchange that don’t quite look finished.

Ever wonder what’s going on there?

The ramps were actually built during the first phase of the Loop 303/I-10 traffic interchange project, which wrapped up in 2014 when the “north half” of the interchange opened to traffic.

That north half includes four ramps that connect the Loop 303 to I-10 and allow drivers to travel from:

  • southbound Loop 303 to both east- and westbound I-10
  • eastbound and westbound I-10 to northbound Loop 303

Just last week, ADOT has started work on the “south half” of the interchange that will complete the four remaining ramps to connect the two freeways and extend Loop 303 south to Van Buren Street. The improvements also will allow traffic to make connections between Loop 303 and Cotton Lane south of Van Buren Street.

We’ll tell you more about that in a second, but first let’s get back to those “unfinished” ramps and why they were built early…

There are a couple of reasons, including safety.

Having portions of the ramps already built allows the contractor to limit how much work is done directly over I-10 during this new phase of the project. It also reduces the construction-related restrictions that will be necessary on I-10 during the project (good news, right?!?).

2016-0229-1loop303

Ramps were built early for a couple of reasons, including safety.

As we mentioned up top, crews have already started work on the next “south half” phase of the project, scheduled to be completed by early 2018.

In the initial stages, crews will work on building a paved construction-bypass route along Van Buren Street near Cotton Lane.

The temporary lanes will allow Van Buren Street traffic to use a curved detour route around freeway bridge construction.

The bypass will limit restrictions and allow crews to safely build a new Loop 303 bridge over Van Buren Street without traffic traveling directly under the structure.

The first stage of work also will focus on construction of the westbound I-10 to southbound Loop 303 ramp and the northbound Loop 303 to westbound I-10 ramp. The project also will add ramps connecting eastbound I-10 to southbound Loop 303 as well as northbound Loop 303 to eastbound I-10.

The improvement work will require temporary lane restrictions and closures near the interchange. Portions of the I-10 frontage roads in areas between Sarival Avenue and Citrus Road will be closed at times. The project also will add a top layer of smooth rubberized asphalt on I-10 in the area of the Loop 303 interchange.

PHOENIX – Work to complete the freeway-to-freeway interchange linking Loop 303 with Interstate 10 in Goodyear is underway this week, according to the Arizona Department of Transportation.

As part of the $83 million project to build the south half of the traffic interchange, crews will complete the four remaining ramps to connect the two freeways and extend Loop 303 south to Van Buren Street. The improvements also will allow traffic to make connections between Loop 303 and Cotton Lane south of Van Buren Street.

The project is the second of two phases to construct the interchange and is scheduled to be completed by early 2018.

The north half of the interchange, which opened to traffic in August 2014, already allows drivers to save travel time by making direct connections on the ramps between I-10 and Loop 303 north of the interstate.

In the initial stages of the new project, crews will work on building a paved construction-bypass route along Van Buren Street near Cotton Lane. The temporary lanes will allow Van Buren Street traffic to use a curved detour route around freeway bridge construction. The bypass will limit restrictions and allow crews to safely build a new Loop 303 bridge over Van Buren Street without traffic traveling directly under the structure.

The first stage of work also will focus on construction of the westbound I-10 to southbound Loop 303 ramp and the northbound Loop 303 to westbound I-10 ramp. The project also will add ramps connecting eastbound I-10 to southbound Loop 303 as well as northbound Loop 303 to eastbound I-10.

The improvement work will require temporary lane restrictions and closures near the interchange. Portions of the I-10 frontage roads in areas between Sarival Avenue and Citrus Road will be closed at times.

The project also will add a top layer of smooth rubberized asphalt on I-10 in the area of the Loop 303 interchange.

Funding for the new project is provided through the Maricopa Association of Governments’ Regional Transportation Plan approved by county voters in 2004. Sources of construction funds in the regional plan include a local half-cent sales tax for transportation and the Phoenix region’s share of federal highway funds.

With hundreds of blog posts in our archives, we understand if you haven’t had a chance to read them all.

However, there’s a lot of interesting content in those early posts and we don’t want you to miss out. That’s why we’re looking back and highlighting some of our favorites in a series called, “From the Rearview Mirror.”

**********

Originally published one year ago, this blog post highlights a very big milestone: the completion of all four ramps connecting Loop 303 and I-10. The post and the video mark the conclusion of a project that started back in 2011. That new interchange was – and still is – important, not just for West Valley drivers, but to the entire state because of its ability to help to expand commerce while also easing travel throughout the region.

We’ve blogged a lot about the Loop 303 and we’re not done yet. In the coming weeks, we’ll be sharing some updates on the continued improvements to the freeway. Several projects, stretching from I-10 to Happy Valley Parkway, are designed to improve traffic conditions.


All ramps are open at the Loop 303/Interstate 10 traffic interchange

Have you heard the news? All four of the ramps connecting Loop 303 and I-10 are open!

We told you about the first two ramps (southbound Loop 303 to eastbound I-10 and eastbound I-10 to northbound Loop 303) last month. Shortly after that, the two additional ramps (westbound I-10 to northbound Loop 303 and southbound Loop 303 to westbound I-10) opened up to drivers on Aug. 24.

As you can see in the video above, there’s also a frontage road system connecting Sarival Avenue to Citrus Road – it is expected to open by mid-September and is the last piece of this phase of the interchange project. Phase II of the project, which will provide southbound access from I-10 to Van Buren Street, is currently in design and is expected to begin construction in 2016.

Looking back

Work on the interchange started in late 2011 and we’ve been covering the project’s progress along the way. We thought it might be fun to look back at some of those posts and videos. After you finish watching the video above, check out these links to learn more about:

Of course, the interchange is just one part of the improvements happening along the Loop 303 corridor. ADOT is working to improve Loop 303 to create a six-lane freeway with three general-purpose lanes in each direction between I-17 in Phoenix and I-10 in Goodyear.

PHOENIX – A weekend closure of Grand Avenue (US 60) near Loop 303 in Surprise will be in place Friday night until Monday morning while crews continue to build the new Loop 303 bridge over US 60, according to the Arizona Department of Transportation.

Grand Avenue will be closed between Loop 303 and R.H. Johnson Boulevard/Sunrise Boulevard from 9 p.m. Friday, July 10, to 5 a.m. Monday, July 13.

Grand Avenue traffic will primarily be detoured along Loop 303 and Bell Road while the weekend closure is in place.

Southbound Loop 303 drivers in the Peoria area also can connect with Grand Avenue via southbound El Mirage Road and westbound Bell Road.

Depending on their destination, drivers on southeast-bound US 60 can also consider additional detour routes including eastbound State Route 74 to southbound Lake Pleasant Parkway or southbound I-17.

Crews this weekend will be adding what is known as a false deck and other components of the new bridge. Fourteen steel-reinforced concrete girders were placed over Grand Avenue last month as part of ADOT’s $46 million project to improve the interchange connecting Loop 303 and US 60 in Surprise. The project is scheduled for completion in summer 2016.

Another weekend closure of Grand Avenue is currently scheduled for the first weekend in August to allow concrete for the deck of the new Loop 303 bridge to be poured. When finished, the new bridge will carry northbound Loop 303 traffic. The existing parallel bridge will carry southbound Loop 303 traffic.

Work on the Loop 303 continues out in the West Valley…

As you can see in the video above, a project to improve and expand the Loop 303/US 60 (Grand Avenue) traffic interchange is underway.

The project, which kicked off in December 2014, will widen Loop 303 into a six-lane freeway at the interchange and add a new bridge next to the existing Loop 303 bridge over Grand Avenue. When completed, the new span will carry three new northbound/eastbound Loop 303 lanes, allowing the existing bridge to carry three southbound/westbound lanes. The improved interchange will feature new on- and off-ramps connecting Loop 303 and US 60.

Good news for West Valley drivers – the project also will allow for the removal of the last traffic signal along the mainline of the 36-mile stretch of Loop 303 between Interstate 17 in north Phoenix and Interstate 10 in Goodyear!

You can read more about other Loop 303 projects in our previous posts.

PHOENIX — The new year is shaping up to be a big year for the Arizona Department of Transportation, as the agency will be working on several new and existing projects that will aid economic development and support the efficient movement of goods and services across the state.

All of the projects will be funded with federal and state highway funds, which are collected through gas and vehicle license taxes. In the Phoenix and Tucson metropolitan areas, voters have approved supplemental tax revenue that enables more transportation projects to move forward in their respective regions. 

Phoenix-Area Projects for 2015

Loop 202 South Mountain Freeway
ADOT expects to release the Record of Decision for the long-proposed South Mountain Freeway this spring and work toward selecting a contractor for the proposed $1.9 billion project. The 22-mile-long freeway would run east and west along Pecos Road and then turn north between 55th and 63rd avenues, connecting with I-10 on each end. The South Mountain Freeway is also part of the Regional Transportation Plan funding passed by Maricopa County voters in 2004 through Proposition 400. 

Loop 101 and Loop 202 Widening Projects in East Valley
Much of the focus on freeway improvements in the metro Phoenix area will remain on projects that broke ground in 2014 and are due for completion in 2016. The $73 million Loop 101 widening project between Shea Boulevard and Loop 202 (Red Mountain Freeway) in the Scottsdale area is adding an additional lane in each direction along 11 miles of the Pima Freeway, as well as merge lanes between most major interchanges. The $109 million project to widen the Loop 202 Red Mountain Freeway between Loop 101 in Tempe and Broadway Road in east Mesa also will advance, with new general purpose lanes being added between Loop 101 and Gilbert Road, along with HOV lanes between Gilbert Road and Broadway Road.

Interstate 10/Loop 303 Interchange
Among the new freeway projects scheduled to start this year is the “south half” of the Interstate 10/Loop 303 Interchange, which will complete all ramp connections between the two freeways in Goodyear. Work is expected to start this fall. The north half of the interchange opened last August and, combined with a widened Loop 303 north of I-10, has been embraced by West Valley communities as much-needed infrastructure to help drive economic development in the region. 

Additional Loop 303 Improvements in Northwest Valley
Farther north along Loop 303, ADOT will launch a project to add an interchange at El Mirage Road by this spring. The new interchange will be built at the same time that crews are improving Loop 303 into a six-lane freeway between Grand Avenue (US 60) and Happy Valley Parkway in Peoria. A third project already underway is creating improved connections at the Loop 303/Grand Avenue interchange. All three projects are scheduled for completion in 2016.

US 60 Improvements in Surprise
Also in Surprise, a project to build a Bell Road bridge over Grand Avenue (US 60) and new ramps connecting the two roadways is scheduled to start late in the year, after a design-build contracting team is selected by ADOT. 

Tucson-Area Projects for 2015 

Interstate 19 Traffic Interchange Reconstruction (Ajo Way)
In 2015, ADOT will begin work to replace the existing Interstate 19 traffic interchange at State Route 86, also known as Ajo Way, with a single-point urban interchange. The modern interchange will feature a single set of traffic signals, rather than signals at multiple locations. The $86 million project is expected to improve traffic flow and enhance safety for motorists traveling through Tucson’s southwest side. Construction is expected to continue through 2017 and will also include widening I-19 from Ajo Way to Irvington Road and widening SR 86 to three lanes in each direction between 16th Avenue and Holiday Isle.

State Route 77 Widening (Tangerine Road to Pinal County Line)
After starting work in summer 2014, ADOT will continue efforts to upgrade a six-mile section of SR 77 (Oracle Road) between Tangerine Road and the Pinal county line from two lanes to three lanes in each direction. Along with widening the roadway, planned improvements include raised medians, traffic signal and drainage improvements, wildlife crossings, sound walls and multiuse paths. The $33.9 million project is slated to take two years to complete. 

State Route 86 Widening (Valencia to Kinney Roads)
In 2015, ADOT is expected to begin construction on expanding SR 86 (Ajo Highway) in each direction from Valencia to Kinney roads in Pima County, 10 miles west of downtown Tucson. This seven-mile-long, $55 million project in Pima County will enhance safety and improve traffic flow on the highway, which serves as a regional transportation route between Tucson and south-central Arizona. SR 86 provides access to the Tohono O'odham Nation and is widely used to reach the popular tourist destination in Mexico called Puerto Peñasco, also known as Rocky Point.

Statewide Projects for 2015

Northern Arizona

US 93 Widening (State Route 71 to State Route 89 and Antelope Wash sections)
ADOT will continue long-standing efforts to transform the heavily traveled corridor between Phoenix and Las Vegas into a modern four-lane divided highway throughout the entire 200-mile stretch with two US 93 widening projects this year. After beginning last year, ADOT will complete upgrading a three-mile segment of US 93 (Antelope Wash), located approximately 20 miles north of Wikieup (mileposts 101-104) this summer. A second US 93 widening project (State Route 71 to State Route 89), just north of Wickenburg (mileposts 185-190), is expected to break ground this spring. 

State Route 89A Spot Widening (Vista Overlook to JW Powell)
This $22.5 million project is slated to improve safety and traffic flow by widening the roadway and constructing passing lanes entering and exiting Oak Creek Canyon through an eight-mile stretch from the popular tourist destination Vista Overlook to the JW Powell interchange, three miles south of Flagstaff. Design of the project is nearly complete and ADOT hopes to start construction this year.

Interstate 40 Pavement Improvements (various projects)
ADOT has several major resurfacing projects in the works along the nearly 360-mile-long I-40, which is one of Arizona’s Key Commerce Corridors, as it stretches from California to the New Mexico state line, Three major pavement preservation projects are set to take place in 2015. This spring will complete final paving on the Rattlesnake Wash to US 93 (mileposts 57-72) section east of Kingman after the project began last summer. Later this year, ADOT will start two new resurfacing projects east of Flagstaff, including the Navajo county line to Minnetonka (milepost 250-259) and Walnut Canyon to Twin Arrows (milepost 214-218) segments.

US 89 Landslide Repairs (near Bitter Springs)
ADOT is scheduled to reopen US 89 south of Page after the highway was closed on Feb. 20, 2013 after a landslide caused serious damage to the highway near the Echo Cliffs. Major work on the repairs began on Aug. 11, 2014 as crews began excavating nearly one million cubic yards of rock near the highway to build a buttress, which will stabilize and reinforce the mountain slope that carries the roadway. The $25 million repair project remains on target to reopen to traffic this spring, in advance of this summer’s tourism season in Page and Lake Powell. 

Southern Arizona

US 60 Widening (Silver King/Superior Streets)
This spring, ADOT is expected to start a project to convert the last remaining two-lane roadway segment on US 60 between Phoenix and Superior into a modern, four-lane divided highway. The $45 million project (mileposts 222-227), which will also include improving the urban section of highway in Superior, is expected to take two years to complete.

US 95 Fortuna Wash Bridge
This $13.5 million project is part of a larger corridor improvement project for US 95, the north and south corridor between Yuma and Quartzsite. US 95 is also the main route to the Yuma Proving Ground, which is one of the largest employers in Yuma County and one of the Army’s busiest training sites in the U.S. This project includes a bridge over Fortuna Wash, which often floods during heavy rains. This project is scheduled to begin in the spring.

US 95 San Luis Street Improvements
This $11 million project includes reconfiguring San Luis Port of Entry traffic off US 95 in San Luis to facilitate business along Main Street. The project, which began in October 2014, will help the circulation of traffic, enhance pedestrian safety and improve access to downtown businesses near the U.S.-Mexico international border. Work will be completed this year.

Major Studies

Interstate 11
ADOT’s Interstate 11 and Intermountain West Corridor Study continues to move forward. This year, work will begin on an Environmental Impact Statement which will allow ADOT to begin an environmental study in the area between Nogales and Wickenburg, part of the proposed Interstate 11 and Intermountain West Corridor. The $15 million Tier 1 Environmental Impact Statement is expected to take three years to complete, once work gets underway later this year. Interstate 11, which will connect Arizona to the entire Intermountain West, is one of our state’s Key Commerce Corridors. I-11 is being planned as a multimodal freight corridor and a manufacturing belt that will drive trade, commerce, job growth and economic development while facilitating strong connections to other major markets.

Passenger Rail
The next major step for ADOT’s Passenger Rail Corridor Study: Tucson to Phoenix is to publish the Draft Environmental Impact Statement for public review. Three public hearings will be held later this year in Maricopa, Pinal and Pima counties to allow community members to comment on the recommendations of the study. Following the public review process, the final recommendations and environmental considerations will be issued on the Final Environmental Impact Statement for federal approval. ADOT is currently evaluating three final rail alternatives. The Passenger Rail Corridor Study is expected to be completed later this year. ADOT’s mission is to evaluate and implement modes of transportation to provide a well-balanced, flexible transportation system that moves people and commerce throughout Arizona.

When we last left off with the Loop 303, all ramps had just opened at the freeway’s I-10 traffic interchange. Months later, more improvements are still on the way…

We’re talking about three new projects, all north of the Loop 303/I-10 interchange, stretching from US 60 (Grand Avenue) to Happy Valley Parkway. Each project is designed to help improve traffic conditions in the northwest valley. We’ll definitely have more information on each of these projects in the months to come, but for now, here’s a quick overview of what drivers can expect.

Loop 303 / US 60 (Grand Avenue) Traffic Interchange

Construction to improve and expand the traffic interchange linking Loop 303 and US 60 (Grand Avenue) in Surprise began this week.

2014-1210-303-2

View of the Loop 303/US 60 (Grand Avenue) traffic interchange project area.

This project will widen Loop 303 into a six-lane freeway between Mountain View Boulevard and the US 60 traffic interchange and add a new bridge next to the existing Loop 303 bridge over Grand Avenue. When completed, the new span will carry three new northbound/eastbound Loop 303 lanes, allowing the existing bridge to carry three southbound/westbound lanes.

The improved interchange will feature new on- and off-ramps connecting Loop 303 and US 60. The project also will allow for the removal of the last traffic signal along the mainline of the 36-mile stretch of Loop 303 between Interstate 17 in north Phoenix and Interstate 10 in Goodyear.

As work kicks off, one of the first things that drivers will notice is the construction of sound walls.

This week, crews will start construction of the sound wall on the west/southbound side of Loop 303 between Mountain View Boulevard and US 60. Construction of the sound wall on the east/northbound side of Loop 303 between Mountain View Boulevard and US 60 is anticipated to start in January 2015.

Other initial work starting this week includes shoulder improvements along the south side of Grand Avenue near the interchange. Crews are scheduled to begin closing the left lanes of Grand Avenue in both directions on Wednesday, Dec. 10, starting at Sunrise Boulevard and moving north for median work.

Grand Avenue traffic will be shifted to the wider south side of the roadway by early January, allowing two travel lanes in each direction between 163rd Avenue and Sunrise Boulevard. The speed limit on this section of Grand Avenue will be reduced from 55 to 45 mph throughout the duration of the 18-month project. Drivers are reminded to slow down and be alert when traveling in the work zones.

Loop 303 – Grand Avenue to Happy Valley Parkway
Right now, construction is underway to widen the Loop 303 from a four-lane to a six-lane (three in each direction) freeway between Grand Avenue and Happy Valley Parkway in Peoria. Sound walls are also a part of this project.

The roadway improvements will be utilizing material from the existing roadway and the lanes will have a rubberized asphalt paved surface once complete.

Loop 303 / El Mirage Traffic Interchange

Finally, there’s the Loop 303/ El Mirage Traffic Interchange. Construction is expected to start in early 2015 on this project that will add a Loop 303 traffic interchange at El Mirage Road.

When this project is finished, Loop 303 traffic will travel over El Mirage Road as part of the new interchange, which will include on- and off-ramps connecting the two roadways. Sound wall construction, new freeway lighting and drainage improvements are also part of the plan.

Stay updated

All three of the Loop 303 projects in the northwest Valley are scheduled for completion by summer 2016.

PHOENIX — A project to improve and expand the traffic interchange linking Loop 303 and US 60 (Grand Avenue) in Surprise is scheduled to start the week of Dec. 8, according to the Arizona Department of Transportation.

The $46 million project will widen Loop 303 into a six-lane freeway at the interchange and add a new bridge next to the existing Loop 303 bridge over Grand Avenue. When completed, the new span will carry three new eastbound Loop 303 lanes, allowing the existing bridge to carry three westbound lanes.

The improved interchange also will feature new on- and off-ramps connecting Loop 303 and US 60. The project also will allow for the removal of the last traffic signal along the mainline of the 36-mile stretch of Loop 303 between Interstate 17 in north Phoenix and Interstate 10 in Goodyear.

Sound wall construction is scheduled to start Monday along Loop 303 north of Mountain View Boulevard in the Sun City Grand area. Crews will be constructing walls over the next few months to limit the level of traffic noise in the area.

Other initial work starting next week will include shoulder improvements along the south side of Grand Avenue near the interchange. Crews are scheduled to begin closing the left lanes of Grand Avenue in both directions on Wednesday, Dec. 10, starting at Sunrise Boulevard and moving north for median work.

Grand Avenue traffic will be shifted to the wider south side of the roadway by early January, allowing two travel lanes in each direction between 163rd Avenue and Sunrise Boulevard. The speed limit on this section of Grand Avenue will be reduced from 55 to 45 mph throughout the duration of the 18-month project.

Earlier this year ADOT started work on another project to widen Loop 303 from a four-lane to a six-lane freeway between Grand Avenue and Happy Valley Parkway in Peoria.

Next year ADOT will break ground on a third project in the area to add a Loop 303 traffic interchange at El Mirage Road. Loop 303 will travel over El Mirage Road as part of the new diamond interchange, which will include on- and off-ramps connecting the two roadways.

All three of the Loop 303 projects in the northwest Valley are scheduled for completion by summer 2016.
