Broadway Road in Tempe to close in both directions nightly (April 19-22) between 48th and 52nd streets

PHOENIX – Motorists who travel on Broadway Road between 48th and 52nd Streets at night, should be prepared to take detours beginning Tuesday, April 19, through Friday, April 22. Construction crews with the Interstate 10 Broadway Curve Improvement Project will close Broadway Road in both directions for bridge work nightly from 8 p.m. to 4 a.m. The westbound I-10 on-ramp and the eastbound off- and on-ramp at Broadway Road will also be closed.

Drivers on Broadway Road who need to access westbound Broadway Road should travel north on Priest Drive to University Drive, head west on University Drive to State Route 143 and travel south on SR 143 to access Broadway Road west of the closure. Drivers on westbound I-10 who need to access westbound Broadway Road should exit at 40th Street and use southbound 40th Street to access Broadway Road west of the closure.

Drivers on Broadway Road who need to access eastbound Broadway Road should travel south on 48th Street to Southern Avenue and travel east to northbound Priest Drive to access Broadway Road east of the closure. Drivers on eastbound I-10 who need to access eastbound Broadway Road should exit at Baseline Road and use eastbound Baseline Road to northbound Priest Drive to access Broadway Road east of the closure.

Interstate 10 closed in both directions between SR 51 and SR 143 the weekend of April 22-April 25

April 25, 2022

PHOENIX –The Arizona Department of Transportation advises motorists to expect delays and allow plenty of extra travel time while Interstate 10 is closed to east and westbound travel between SR 51 and SR 143 the weekend of April 22-April 25 to accommodate work related to the I-10 Broadway Curve Improvement Project.

The closure is scheduled from 10 p.m. Friday, April 22, through 4 a.m., Monday, April 25. Motorists should plan ahead for detours along the state highway system and anticipate travel delays.

Salt River Project crews are relocating a large overhead power line that currently stands in the way of widening I-10 in conjunction with the I-10 Broadway Curve Improvement Project. While SRP’s closure is in place, Broadway Curve Constructors (BCC) will take advantage of the opportunity to shift the work zone on I-10 and make repairs to the freeway’s pavement. By combining this work with the SRP closure, BCC can eliminate the need for a separate highway closure, as well as further inconvenience for the traveling public.

Here’s what to expect:

Eastbound I-10 will be closed between SR 51 and SR 143. The eastbound I-10 on-ramps between Third and 40th streets; the southbound I-17 on-ramps at Seventh Avenue and Seventh Street; the westbound Loop 202 (Red Mountain Freeway) ramp to eastbound I-10; the southbound SR 51 on-ramp at McDowell Road and the ramp from southbound SR 51 to eastbound I-10 will be closed.
Westbound I-10 will be closed between SR 143 and I-17. The westbound I-10 on-ramps between Elliot Road and 32nd Street, the westbound US 60 (Superstition Freeway) on-ramp at Mill Avenue and the westbound US 60 ramp to westbound I-10 will be closed.

Eastbound I-10 Detour: Continue east on the Loop 202 (Red Mountain Freeway) to southbound Loop 101 (Price Freeway) and westbound Loop 202 (Santan Freeway) to access eastbound I-10. Drivers traveling on southbound I-17 can use westbound I-10 to eastbound Loop 202 (Drivers should avoid westbound US 60 west of Loop 101 in Tempe due to lane restrictions.)

Westbound I-10 Detour: Exit onto eastbound US 60 before traveling north on Loop 101 to westbound Loop 202 in order to access westbound I-10. (Drivers can also use eastbound and westbound Loop 202 (Santan/South Mountain Freeway) as alternate detour routes.)

Motorists heading to the West Valley: Bypass the closure by using west- and northbound Loop 202 (South Mountain Freeway) and connecting with I-10 at 59th Avenue.

Phoenix Sky Harbor International Airport traffic: Allow extra travel time and use the east entrances from Loop 202 and SR 143.

PHOENIX – Motorists who drive over the 55 mph speed limit while traveling through the Arizona Department of Transportation’s largest-ever urban freeway reconstruction project could end up getting a ticket as ADOT increases its efforts to encourage motorists to slow down in the project work zone.

In the Phoenix-metro area, the Interstate 10 Broadway Curve Improvement Project stretches for 11 miles from the Loop 202 Santan/South Mountain Freeway interchange to I-17 near Phoenix Sky Harbor International Airport. The ADOT project team is initiating a campaign to raise awareness of work zone safety that includes added Department of Public Safety patrols in the area.

“The I-10 Broadway Curve Improvement Project is one of the most visible work zones in the state, but speeding through any work zone can be deadly and costly for drivers, their passengers and of course workers in these zones,” said Project Manager Amy Ritz.

She added, “One aspect of this project that has taken me by surprise is the number of people who risk their lives, and the lives of others every day, to save about three minutes. That’s how much time you save if you drive these 11 miles at 75 mph compared to the posted 55 mph limit. The time it takes to listen to a hit song is not worth someone’s life.”

In addition to the added enforcement, ADOT is using overhead message signs and billboards to share safety information and has produced a public service announcement featuring I-10 Broadway Curve project team members asking drivers to slow down.

Whether a work zone is a major construction project or a one-day repair and maintenance job, drivers should expect the unexpected, always obey speed limits, never drive distracted or impaired, and be especially vigilant and patient.

1,000 cubic yards of concrete poured for new Broadway Road bridge

1,000 cubic yards of concrete poured for new Broadway Road bridge

January 25, 2022

What takes 11 hours to empty, weighs just over 2,000 tons and can cover a football field half a foot deep? It's the 1,000 cubic yards of concrete that was poured over the weekend in conjunction with the Arizona Department of Transportation's Interstate 10 Broadway Curve Improvement Project.

On Saturday, I-10 Broadway Curve Improvement Project crews completed a critical step for the foundation that will support the new Broadway Road bridge that is being constructed over I-10. They poured 1,000 cubic yards of concrete to create what is called a “bridge footing.” This footing is a large concrete slab that will play an important role in the support and distribution of weight for the new bridge.

The new bridge over I-10 is one of several bridges being replaced or widened as part of the I-10 Broadway Curve Improvement Project. Crews will take down the existing Broadway Road bridge after the new one is completed later on in the project.

It’s go time! If you’ve noticed things are starting to look a little different on Interstate 10 in the Southeast Valley, you’re not alone. Crews have started the first phase of work to remove rubberized asphalt from the roadway. The process is the first step in more than three years of major reconstruction work on one of the busiest sections of interstate freeway in Arizona, and it’s all part of the I-10 Broadway Curve Improvement Project.

Crews with Broadway Curve Constructors kicked off the project on July 23 with the removal of one inch of rubberized asphalt along approximately five miles of westbound I-10 between Loop 202 and US 60 (Superstition Freeway). During the first closure of westbound I-10, five milling machines got to work grinding off the top layer of rubberized asphalt, creating 13,500 tons of material and filling 575 truckloads. Much of that material will be recycled. Similar removal work is scheduled on I-10 over weekends through September. You can find closure and detour information on the project website.

Removing the top layer of rubberized asphalt is important so construction crews can establish their work zones and shift the travel lanes as required throughout construction. For a project of this size and scope, we anticipate dozens of work zone and travel lane shifts. With the application and removal of temporary lane striping for each change, this would create significant wear and tear on the pavement surfaces. Also, when the rubberized asphalt is taken off, workers can inspect the concrete pavement and repair areas that are cracking or beginning to break.

Drivers might notice that I-10 looks different after the rubberized asphalt has been removed. The payoff will come at project completion, when a safer, wider and more efficient highway will be ready for the approximately 300,000 drivers who take the route every day.

In the coming weeks, ADOT anticipates construction will begin on the ambitious Broadway Curve Improvement Project, the first major urban freeway reconstruction project in Maricopa County.

The four-year project will bring improvements, additions and extra lanes to 11 miles on and around I-10, from the Loop 202 (Santan/South Mountain Freeway) to Interstate 17 near Phoenix Sky Harbor International Airport.

If you’ve driven the route recently you may be wondering what’s with all the large drilling equipment and weekend activity if construction on the project hasn’t started yet?

The work you’re seeing is pre-construction geotechnical work. Crews are boring and drilling to test the soil conditions deep below the surface, a necessary first step prior to any freeway construction project.

Crews began this preliminary work in mid-April, assessing the condition of soil, rock and depth of groundwater along the Broadway Curve Improvement Project alignment. This type of testing is essential to test the conditions of the earth underneath planned or existing structures, such as bridges, walls and freeway lanes.

The 40-foot-tall vehicles you’re seeing are truck-mounted Becker Hammer drill rigs, which bore deep into the soil and bring up a sample. The rigs can drill down as deep as 175 feet below the surface.

For this project, these drills will generally sample from 80 to 125 feet deep if the boring is for bridge construction, and generally from 20 to 60 feet deep to test underneath future freeway walls. Once samples are collected they go to the lab, where the contents are tested and evaluated.

In turn, the results of the tests and evaluations help determine how to design and build the highway and its many structures.

“If the underlying soils are soft or loose, the foundation will need to be larger and deeper,” said Ramon Padilla, P.E., geotechnical project manager for Broadway Curve Constructors. “We are exploring what’s beneath the ground to evaluate the engineering properties of the subsurface (below ground) soil conditions, and design the foundations that will support the planned structures.”

Padilla said this geotech work will last at least a few more months and could overlap with the start of construction.

The Broadway Curve Improvement Project is on 11 miles of I-10 between the Loop 202 (Santan/South Mountain Freeway) and I-17 near Phoenix Sky Harbor International Airport. Additional work will occur on approximately 1 mile of east- and westbound US 60 (Superstition Freeway) between I-10 and Hardy Drive, and on approximately 1 mile of north- and southbound State Route 143 between I-10 and the southern end of the SR 143 bridge over the Salt River.
