Construction to proceed on I-10 Broadway Curve Improvement Project in Arizona

Oct. 21, 2021

Most work on ADOT’s largest urban freeway reconstruction project will occur on east- and westbound I-10

The Arizona Department of Transportation (ADOT) has issued the formal Notice to Proceed for the I-10 Broadway Curve Improvement Project.

As a result of this action, ADOT is allowing Broadway Curve Constructors to begin construction in earnest on the 11-mile project, according to a press release.

Most work on ADOT’s largest urban freeway reconstruction project will occur on east- and westbound I-10 between the Loop 202 (Santan/South Mountain Freeway) and I-17. Additional work will occur on east- and westbound U.S. 60 (Superstition Freeway) between I-10 and Hardy Drive and on north- and southbound State Route 143 between I-10 and the Salt River.

Broadway Curve Constructors began pre-construction activities this spring, including utility relocation, geotechnical investigation, work zone setup, and removal of the rubberized asphalt. In the coming weeks, ADOT anticipates construction to begin on the median concrete barrier walls in the west segment, and in the east segment where native plants and trees will be salvaged so they can be transplanted when construction is complete. 

Most of the immediate construction will occur in the east segment on eastbound I-10 between Baseline and Ray roads, where crews will begin to do earthwork, modify catch basins, and extend storm drain pipes. 

Through 2022, crews will widen eastbound I-10 in the east segment. They will also build sound walls where warranted and begin widening the Guadalupe Road bridge over east- and westbound I-10. ADOT anticipates all improvement work on eastbound I-10 between Baseline and Ray roads to be complete next year.

The I-10 Broadway Curve Improvement Project is identified in the Maricopa Association of Government’s Regional Transportation Plan, funded by a half-cent sales tax approved by Maricopa County voters in 2004 through Proposition 400.
