Loop 303

We're excited to share that an ADOT project that added Loop 303 interchanges at 43rd and 51st avenues is a national finalist for top honors in the 2024 America’s Transportation Awards. We also want Arizonans to know that one of those honors, the People’s Choice Award, is decided by the public.  

To help keep traffic moving through the work zone, Loop 303/Sonoran Desert Drive will be closed under I-17. Eastbound Loop 303 traffic can reach northbound I-17 by taking I-17 southbound to Happy Valley Road. 

The $70 million project is a top 12 finalist in the 2024 America’s Transportation Awards competition, making it eligible for the Grand Prize and the People’s Choice Award. You can vote for the People’s Choice Award once daily through Oct. 29.

A recent Arizona Department of Transportation project that constructed Loop 303 interchanges at 43rd and 51st avenues near Interstate 17 is a winner in the 2024 America’s Transportation Awards competition that includes a focus on community development.

A long stretch of Loop 303 is the latest to undergo an oil-based treatment to extend the life of the pavement on Valley freeways.

If you couldn't make it to last week's Loop 303 meeting, we have a rundown of the what you missed.

PHOENIX – A two-week project to resurface areas along eastbound Grand Avenue (US 60) northwest of Loop 303 in Surprise is scheduled to begin on Monday, Oct. 30, according to the Arizona Department of Transportation.

Drivers should plan on lower speed limits, lane restrictions and the closure of some median turning areas in areas between 163rd Avenue and Happy Valley Road during both day and overnight hours.

The following restrictions are scheduled:

West Valley drivers have improved freeway access with the opening of new freeway ramps. It's all part of building you a better freeway.

GOODYEAR – Major work on the freeway interchange connecting Interstate 10 and Loop 303 in the West Valley has been completed.

The Arizona Department of Transportation has now opened all four of the new ramps that allow drivers to make direct connections between I-10 and Loop 303. Three ramps were opened to traffic Sunday night, Oct. 8. Construction crews on Monday opened the fourth ramp, which connects westbound I-10 to southbound Loop 303.

A new section of Loop 303 traveling under I-10 between Thomas Road and Van Buren Street in Goodyear also is open to traffic.

Frontage-road construction rarely gets attention within a larger freeway project, but that isn't the case with work underway in Goodyear.

GOODYEAR – Crews working to build the last phase of the Loop 303/Interstate 10 traffic interchange in Goodyear have reached another milestone.

New stretches of separate north- and southbound Loop 303 frontage roads between McDowell Road and Van Buren Street opened to traffic as scheduled on Saturday, Aug. 19, according to the Arizona Department of Transportation.

If you think you've spotted an Arizona highway on the the big screen, you're probably right.

GOODYEAR – With each strand of reinforcing steel put in place and each truckload of earth moved, the Arizona Department of Transportation’s $63 million project to complete a traffic interchange linking Loop 303 with Interstate 10 in the West Valley continues to take shape.

Plans call for the “south half” of the interchange, which includes extending Loop 303 south from Thomas Road to Van Buren Street, to open to traffic by late fall. This work started nearly a year ago.

Before we talk about Phoenix-area projects coming this year, let's look in the rearview mirror at 2016 accomplishments.

PHOENIX – With Valley drivers benefiting from several freeway improvement projects completed during 2016, including the widening of Loop 101 between Shea Boulevard and Loop 202 (Red Mountain Freeway) in the Scottsdale area, the Arizona Department of Transportation is poised to start or complete several Phoenix-area projects in the coming year.

ADOT’s highlights for the regional freeway system in 2017 include:
