Loop 303/Interstate 10 Traffic Interchange Construction
Fall 2011-Fall 2014
The Arizona Department of Transportation has begun construction on the new Loop 303/I-10 Interchange in Goodyear. When completed in Fall 2014, motorists can expect:
- Ramp connections between Loop 303 and I-10, similar to the Loop 101 and I-10 Interchange in Tolleson and Avondale
- Loop 303 widened to a six-lane freeway (three lanes in each direction) extending from I-10 in Goodyear to
US 60 in Surprise
The upcoming launch of the interchange's construction follows a major series of projects that began in 2008 to reconstruct and widen I-10 between Loop 101 and Verrado Way. The following is an overview of the three now-completed I-10 widening projects:
- I-10 Widening between Loop 101 and Sarival Avenue: $81 million project included the addition of two new left lanes in both directions – including High Occupancy Vehicle lanes. Work started in February 2008 and was completed in December 2009.
- I-10 Additional Widening between Dysart Road and Sarival Avenue: $31 million project included adding new right lanes plus widening bridges in this area. Work started in November 2009 and was completed in August 2011.
- I-10 Widening between Sarival Avenue and Verrado Way: $22 million Stimulus-funded project included adding new third lanes in each direction. Work began in September 2009 and was completed in August 2011.
As part of the Loop 303/I-10 Interchange project, sound walls are being constructed in residential areas along I-10 where warranted in accordance with scientific noise studies. ADOT has one of the most stringent noise-reduction policies in the nation, working to mitigate noise when the decibel level is 64 or higher- compared to a minimum level of 67 decibels mandated by the federal government. Sound wall construction will be on-going throughout the construction project.

Sound wall completion
Fall 2012: Canada Village, Canyon Trails east of Sarival Ave.
Fall 2014: Canyon Trails west of Sarival Ave.
ADOT will also pave the Loop 303 with rubberized asphalt. Not only does rubberized asphalt reduce traffic noise by at least 4 decibels, but it also provides a smoother ride.

Other upcoming improvements along I-10
Another near-term I-10 improvement project is currently undergoing final design and is scheduled to start construction next year. A new interchange will be built at Perryville Road, adding more freeway access options in the area of the new Loop 303/I-10 interchange.
