A number of improvements were made to the Phoenix-area freeway system during 2020, including new lanes, upgraded interchanges and other work designed to enhance safety and traffic flow. Here’s a Year in Review of Phoenix area Interstate 10 projects completed by the Arizona Department of Transportation:
Interstate 10 new lanes added in both directions at the Loop 101 (Agua Fria Freeway) interchange in the West Valley.
During spring 2020, ADOT adjusted lane striping along eastbound I-10 to provide two lanes, instead of just one, for traffic approaching the ramp to northbound Loop 101. The move reduced sudden lane changes and collisions in the area by increasing traffic capacity.
Traffic flow also was improved along westbound I-10 with the extension of a right through lane near the Loop 101 interchange. The safety project was done in partnership with the Arizona Department of Public Safety and Maricopa Association of Governments, the Valley’s regional planning agency.
