Ready to Rubble College tour

We came, we saw, we rubbled! 

The April 22-23 “Ready to Rubble” event wrapped up another major milestone for the I-10 Broadway Curve Improvement Project—the removal of the old 48th Street and Broadway Road bridges over Interstate 10. This milestone generated a great deal of interest from all over the Valley.  

Of all those in attendance, one particular group of spectators brought a youthful energy to the event. Students from the University of Arizona, Arizona State University and Peoria’s MET Professional Academy were on hand to see the removal process. After the event, many of them said they were excited to see how rewarding a career in engineering might be–some even suggested that working for the Arizona Department of Transportation would be a great experience. 

Sofia Iliev, a sophomore at the University of Arizona, went on the 60-minute tour to see the removal process of the 48th Street and Broadway Road bridges. Students and guests boarded buses and toured the work site, seeing all the shearing and hammering from a safe distance. Iliev said she has visited other sites, but nothing compared to the scale and scope of the I-10 Broadway Curve Improvement Project. 

“I have seen bridges go up. It’s cool to see them come down,” Iliev said. “I have always been good with building things with my hands, going back to when I built Legos. This is why I’m interested in a career in engineering. Working for an agency like ADOT would be cool.”   

 Robert Samour, ADOT's Senior Deputy State Engineer for Major Projects said he was happy with the success of the tours. 

“I’m glad that students got to see and share the experience of some of the great things happening at ADOT in terms of engineering and the delivery of a major project,” Samour said.

Arizona State University junior Chad Stark said he was looking forward to graduating in 2024 and seeing the completion of the I-10 Broadway Curve Improvement Project, which is scheduled to be finished that same year. He added that talking to ADOT engineering professionals was a “breath of fresh air.” 

“It’s good to see that these [professionals] have an interest and passion for the job they have,” Stark said.  “I’m excited about it. You spend all this time taking classes like Calculus… now we are at the point where we can start seeing this stuff in action.”

Waste Not: Reusing materials from the past to build for the future

Waste Not: Reusing materials from the past to build for the future

Reduce, reuse and recycle: They’re key to protecting natural resources and lessening the amount of trash in our landfills. They’re also an important part of the Interstate 10 Broadway Curve Improvement Project.

"We reuse as much as we can so nothing goes to waste,’ said Kole Dea, P.E., senior resident engineer with the Arizona Department of Transportation. “If something can’t go back into the project, then it’s recycled.”

Asphalt millings, concrete, metal and steel are the most common types of waste; but the project team has future plans for all of them.

Asphalt Millings

The black material you see piled up in the work zone are asphalt millings. When construction began in summer 2021, crews removed the rubberized asphalt from the surfaces of I-10 and US 60 in the project area. That work created 1.3 million square yards of millings, which are being used as the base layer for temporary haul roads in the project area. Millings provide a strong base for trucks and equipment to drive on, and they reduce dust - another plus for the environment. Millings can also be mixed in with dirt to build embankments that will support the roadway. Outside of the project area, ADOT uses millings on its maintenance roads in unpaved areas. 

 

Reusing concrete

Concrete

As walls and other concrete structures are taken down to make way for new construction, they’re broken up so they can serve a new purpose. Crews use equipment to break each piece into sizes no larger than 24 inches.Those pieces are used as fill to build up approaches for new bridges, and can be used to fill in holes or otherwise supplement unstable materials in the project area.

Metal and Steel

Metal and steel products are major components of highway infrastructure, inside and out. In addition to what you can see, they’re also used to reinforce concrete girders and other structures, and strengthen walls. Steel rebar and other materials are broken down and taken to a recycling facility. Fun fact:

Reusable construction debris

Recycled steel is as strong and durable as new steel made from iron ore.

ADOT works in compliance with state and federal regulations to ensure reused materials do not pose a threat to the environment. Careful testing confirms that the paint stripes on milled asphalt don’t contain lead, and that old pipes or bridge structures are free from asbestos. 

As new roadways, ramps and bridges take shape throughout the Broadway Curve work zone, remember how important the infrastructure from the past is to building for the future.

Throwback Thursday: That unmistakable Curve

By John LaBarbera / ADOT Communications
September 29, 2022

Today we throwback to 1966. It was a banner year for transportation in popular culture: Adam West’s Batman debuted, driving his Batmobile all over Gotham City, Star Trek began exploring strange new worlds at warp speed on NBC, and NASA launched Lunar Orbiter 1, the first U.S. craft to orbit the moon.

Here in Arizona, construction of the cross-continental Interstate 10 was taking shape. And if you’ve been here long enough, you immediately know that this photo shows the Broadway Curve in Tempe.

The buttes that hug the interstate are instantly recognizable, as is Broadway Road swooping out from the bottom left corner of the photo. This section of I-10 opened to vehicles in 1968.

What you see in this photo is a stark contrast to the I-10 Broadway Curve Improvement Project now underway in and around the this area. Areas of farmland have been replaced by homes, businesses and Tempe Diablo Stadium, which would open just three years after this photo was taken.

PHOENIX – The Interstate 10 Broadway Curve Improvement Project is updating its detour route information for this weekend’s I-10 closure between the Loop 202 (Santan/South Mountain Freeway) and US 60 (Superstition Freeway).

UPDATED: US 60 is closed in both directions between Rural Road and Loop 101 (Price Freeway) due to water on the roadway. 

  • Eastbound lanes on US 60 are exiting at Rural Road and westbound lanes are being diverted to Loop 101 (Price Freeway). 
  • To bypass this weekend’s I-10 closure, drivers should use the north and southbound Loop 101 (Price Freeway) between the east and westbound Loop 202 - Santan and Red Mountain freeways.

There is no estimated time to reopen the US 60. Drivers should plan for long delays.

Original I-10 Closure information: Westbound Interstate 10 will be closed between the Loop 202 (Santan/South Mountain Freeway) and US 60 (Superstition Freeway) from 10 p.m. Friday, May 6, to noon, Sunday, May 8. Eastbound I-10 will be closed between US 60 and Loop 202 (Santan/South Mountain Freeway) from 8 p.m. Saturday, May 7, to 4 a.m. Monday, May 9, for utility relocation and bridge work.  

The I-10 Broadway Curve Improvement Project is identified in the Maricopa Association of Governments’ Regional Transportation Plan, funded by a half-cent sales tax approved by Maricopa County voters in 2004 through Proposition 400. MAG identified the need for this project to reduce travel times on I-10 during peak hours; improve airport access; support ridesharing and transit; and prepare the region for future growth projections.
