PHOENIX ‒ Almost a year to the day after crews began clearing land to create a wider stretch of Interstate 10 near Eloy, westbound traffic will be switched to the new lanes Thursday, Dec. 6, in an important step forward for a groundbreaking project in Pinal County.

The new westbound lanes run east of the current alignment starting near milepost 213 and reconnect with the existing lanes of I-10 near milepost 209. Eastbound lanes will remain unchanged for about a month and then switch to the new pavement, with this temporary configuration offering two travel lanes in each direction.

The westbound right lane on I-10 will close at milepost 213 at 9 p.m. Wednesday, Dec. 4, to allow crews to make a connection to the new lanes. The right lane will reopen as soon as the work is complete, which is expected to occur before 5 a.m. Thursday.

The project, which is widening I-10 to three lanes in each direction, building a new interchange with State Route 87 and creating a first-of-its-kind dust detection and warning system, is part of ADOT’s focus on enhancing mobility and safety between Tucson and Phoenix. Another project is currently widening I-10 to three lanes in each direction between Earley Road and Interstate 8 in Casa Grande.

When both projects are scheduled for completion by late summer 2019, I-10 will have three lanes in each direction between Tucson and State Route 387 in Casa Grande.

After eastbound traffic is moved to the new pavement near Eloy, crews will demolish the current travel lanes of I-10 and build new eastbound lanes.

The dust detection system will include short- and long-range radar to identify dust storms approaching I-10 and blowing dust along the travel lanes, variable speed limits to slow drivers in dangerous conditions, electronic message boards to inform drivers about the road ahead and closed-circuit cameras to assist ADOT in managing traffic in the area.

ADOT rest areas are far more than places to – well, you know.

Among other things, rest areas provide opportunities to stretch legs, walk pets, have picnic lunches and safely use phones and other mobile electronic devices.

We understand it's a hardship when a rest area closes for a long renovation, and we appreciate your patience while we upgraded facilities at the I-10 Sacaton Rest Area between Phoenix and Casa Grande.

Located at about 30 miles southeast of Phoenix near State Route 387, Sacaton is the only ADOT pit stop along I-10 between Tucson and Phoenix.

Our video team was on hand as Sacaton reopened last week to show the improvements and talk with travelers. We hope you enjoy the video above as well as the many upgrades at; this well-used rest area.

Quietly, without much fanfare, Arizona Department of Transportation crews are moving traffic on westbound Interstate 10 back to the original bridge over Wilmot Road. No ceremony, no ribbon cutting. Just business as usual, and on to the next project.

For the second time in two summers, we used a temporary bridge that allowed us to make repairs and repave the two I-10 bridges over a major Tucson roadway. Back in May, we slid it into position in the median and created a temporary road connecting the bridge with the I-10 lanes that have been carrying traffic in this part of the city since 1965.

For the first three months, eastbound traffic moved to the left, crossed the temporary span, moved back to the right and continued on toward Benson and beyond. Then it was westbound traffic’s turn to do the same thing.

Drivers hardly noticed. The freeway had two lanes open in each direction almost the entire time. There were just a few restrictions on Wilmot Road below the bridges, and most of those took place at night to avoid inconveniencing too many drivers.

Simple.

But that simple, creative effort to use a temporary bridge saved Tucson area drivers more than they realize. Without the bridge, drivers would have been required to merge into the right lane, exit and then re-enter I-10 and get back up to freeway speed. Delays on I-10 would have been tremendous. Life would have been no better on Wilmot Road, which likely would have been closed with detours for most of the nearly six months it took to repair and repave the bridges.

Instead, there were few delays, few restrictions on Wilmot Road and no additional traffic clogging Craycroft and Kolb roads. The I-10 bridges at Wilmot Road are essentially new bridges without the cost or inconvenience of building new ones.

And a month ahead of schedule, well before the coming holidays, our trucks are back in the maintenance yard and our crews are on the way to their next jobs.

Nice work by the men and women in the orange vests and yellow hard hats.

A major step forward this weekend for construction of a Loop 202 South Mountain Freeway interchange in the West Valley will require a westbound closure of Interstate 10 followed by an eastbound closure, according to the Arizona Department of Transportation.

Crews with Connect 202 Partners, the developer of the South Mountain Freeway, will be pouring concrete above I-10 travel lanes to create the deck of a 1,565-foot flyover ramp that will eventually connect to I-10.

Westbound I-10 will be closed between 51st and 67th avenues from 10 p.m. Friday, Oct. 26, to 4 a.m. Saturday, Oct. 27. Eastbound I-10 will then close between 67th and 51st avenues from 4 a.m. Saturday, Oct. 27, to 2 p.m. Sunday, Oct. 28, well before the end of the Arizona Cardinals’ game against the San Francisco 49ers (1:25 p.m. kickoff).

During the westbound closure, traffic exiting at 51st Avenue can detour to the westbound I-10 access road, as well as Van Buren Street or McDowell Road, before re-entering I-10 at 67th Avenue. In addition, the westbound I-10 on-ramps at 27th, 35th and 43rd avenues will be closed to help reduce traffic backups.

During the eastbound closure, traffic exiting at 67th Avenue can detour to Van Buren Street or McDowell Road, before re-entering I-10 at 51st Avenue (the eastbound I-10 access road from 67th and 51st avenues is closed during this work). In addition, the eastbound I-10 on-ramps at 91st, 83rd and 75th avenues will be closed to help reduce traffic backups.

To avoid delays on I-10, motorists should consider alternate routes, including the Loop 101 (Agua Fria Freeway) west of Interstate 17, or exiting I-10 sooner and taking local streets to re-enter past the closure point.

Motorists should also be aware that 59th Avenue will also be closed in both directions between I-10 and Roosevelt Street from 9 p.m. Friday, Oct. 26, to 2 p.m. Sunday, Oct. 28.

During the closures, crews will pump approximately 730 cubic yards of concrete, enough to fill more than 60 dump trucks, into the steel-reinforced deck on the flyover ramp, the longest of five ramps that will be part of the interchange.

Once the concrete is poured, a self-propelled concrete leveling machine called a bidwell will spread the concrete to ensure a flat surface throughout. After the concrete has had an opportunity to cure and reach maximum strength, construction vehicles can travel on the ramp.

The 22-mile South Mountain Freeway, expected to open as early as late 2019, will provide a long-planned direct link between the East Valley and West Valley and a much-needed alternative to I-10 through downtown Phoenix. Approved by Maricopa County voters in 1985 and again in 2004 as part of a comprehensive regional transportation plan, the South Mountain Freeway will complete the Loop 202 and Loop 101 freeway system in the Valley.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.

PHOENIX ‒ A six-month project to replace the deck of the bridge over Interstate 10 at Pinal Air Park Road will begin in early November.

Preliminary work on the $1.85 million project will begin Wednesday, Oct. 24. The bridge will close in early November and remain closed for about four months, temporarily shutting down direct access to and from westbound I-10.

In addition to replacing the deck on the bridge, which was built in 1963, Arizona Department of Transportation crews will repair girders under the bridge.

Drivers on westbound I-10 who want to exit at Pinal Air Park Road (exit 232) should continue north to the Red Rock exit (exit 226), then take eastbound I-10 to Pinal Air Park Road. There will be no restrictions on ramps to and from eastbound I-10.

Drivers on Pinal Air Park Road who want to use westbound I-10 will need to take eastbound I-10 to Marana Road (exit 236).

I-10 will be reduced to two lanes in each direction under the bridge during much of the work.

Following the Maricopa Association of Governments’ announcement that an agreement has been reached with the Gila River Indian Community to study I-10 between the Valley and Casa Grande, Arizona Department of Transportation Director John Halikowski released the following statement:

“We commend our partners at the Maricopa Association of Governments and the Gila River Indian Community for their commitment to improving this essential corridor for personal and commercial travel. Creating a master plan for I-10 between the Phoenix area and Casa Grande will be a major step toward ADOT’s goal of providing three travel lanes in each direction from the Valley to Tucson. As ADOT has made significant investments through the years to increase I-10 capacity between the state’s two largest metropolitan areas, our plans for the 23 miles across the Gila River Indian Community have always recognized the sovereign tribal authority over this area. Through this effort led by the Maricopa Association of Governments, our agencies will work collaboratively to develop a vision and strategy for providing the capacity that I-10 needs today and tomorrow in this corridor.”

Driving along Interstate 10, about halfway between Tucson and Phoenix, you can see that’s something happening off to the east side of the freeway at State Route 87.

Here’s a better perspective. John Dougherty, ADOT’s newly FAA-certified drone pilot, shot this amazing video to capture the whole project from above.

In less than 10 months, crews have built nearly 4 miles of what will become the new westbound lanes of I-10, bridges over both nearby railroad tracks and the future alignment of I-10, freeway ramps and more.

When the work is done about one year from now, drivers will have six new lanes of I-10, a wider new interchange with SR 87 and a dust-detection zone, the first of its kind on US freeways.

Starting Thursday, Oct. 4, SR 87 will close between I-10 and Milligan Road so we can continue work on the new section of SR 87 and complete the new interchange. The closure is expected to continue until mid-December. Drivers can exit I-10 at Sunshine Boulevard and take Casa Grande-Picacho Highway to SR 87. There are no restrictions on I-10.

PHOENIX – State Route 87 will close at Interstate 10 in Eloy the first week of October so crews can complete a new interchange and connect SR 87 with the new westbound lanes being constructed for a wider I-10.

By the time the interchange opens in mid-December, drivers in both directions of I-10 will be using the new pavement that eventually will become the new westbound lanes of I-10.

The work is part of a three-part project to widen and realign I-10, build the new interchange and develop a first-of-its-kind dust detection zone. The new alignment will be between mileposts 209 and 213, with the dust detection zone running from milepost 209 to 219.

The closure, which runs from Milligan Road to I-10, is scheduled to begin Thursday, Oct. 4, and continue through Dec. 14. Drivers can use Sunshine Boulevard (exit 208) and Casa Grande-Picacho Highway to connect between I-10 and SR 87.

Before the closure, crews are scheduled to pour concrete to form the decks of bridges that are part of the new interchange.

The closure will allow construction crews to complete work on the interchange, including a new alignment of SR 87. Once that work is complete, first westbound traffic and then eastbound drivers will be moved off the current I-10 alignment and onto the new pavement.

In early 2019, workers will build the new eastbound lanes and connect them to I-10. The existing travel lanes on I-10 in the area will be demolished.

The project is about 10 miles from a second effort to widen I-10. In Casa Grande, ADOT is widening I-10 from I-8 to Earley Road (mileposts 196-200) by adding a lane in each direction in the median. When both projects are completed by early fall 2019, I-10 will be a six-lane freeway from the north side of Casa Grande to Tucson.

PHOENIX – As drivers on Interstate 10 pass Ina Road in Marana, they have a clear view of a blank space in the middle of a new bridge that soon will carry Ina Road traffic over I-10 and the Union Pacific Railroad tracks.

That small space – where the exit and entrance ramps to westbound I-10 will connect with Ina – is the last major piece in a two-year project to improve traffic flow and driver safety in northwest Pima County.

September marks the start of the final six months on a project that began in February 2017, with completion scheduled by early March.

ADOT is overseeing $128 million in improvements, which are funded by the Federal Highway Administration, the Pima Association of Governments and the Regional Transportation Authority. The town of Marana is contributing $7.9 million toward the cost of the new bridges over the Santa Cruz River west of I-10.

Crews are primarily finishing work that has already started, including creating a new westbound Ina Road bridge over the Santa Cruz River. Girders were put in place earlier this summer, and the concrete deck is set to be poured overnight Thursday and Friday, Sept. 13-14. The eastbound bridge at Ina Road will be closed from 10 p.m. to 5 a.m. both nights for the deck pour on the westbound bridge.

wb-scrb-pre-deck-pour
The westbound Ina Road bridge is expected to open to traffic in January. The eastbound Ina Road bridge, opened in late 2017, is temporarily carrying both directions of traffic.

East of I-10, crews are beginning to work on curbs, gutters and sidewalks before paving begins on Ina Road. The bridge over I-10 is scheduled to open in early 2019. About that time, westbound traffic on I-10 will be moved to new lanes that are currently under construction.

Before work began, Ina Road crossed under I-10, and drivers frequently had to stop for passing freight trains. After completion, Ina Road will cross over I-10 and the railroad tracks. Both Ina Road and I-10 will have an additional lane in each direction to accommodate increasing traffic, with Ina Road improvements reaching west across the Santa Cruz River to Silverbell Road.

The improvements are designed to keep pace with growth in the Marana area while reducing congestion on Cortaro Road.

After work is complete at Ina Road, a similar project is scheduled to begin at Ruthrauff Road. That project will include widening I-10 to four lanes, widening Ruthrauff to two lanes in each direction and building a bridge to carry Ruthrauff over I-10 and the Union Pacific Railroad tracks.  Ruthrauff will be closed at I-10 throughout the 24-month project.
