A number of freeway restrictions are planned in the Phoenix area from January 23 to 26, according to the Arizona Department of Transportation (ADOT). These measures are part of ongoing improvement projects and may require drivers to use detour routes and allow extra travel time.
Northbound and southbound Interstate 17 will be reduced to one lane at times overnight between State Route 74 (Carefree Highway) and Anthem Way. The restrictions will take place from 7 p.m. to 6 a.m. on Friday and Saturday nights for lane striping. Drivers are advised to slow down, merge safely, and be aware that schedules may change due to weather conditions.
Additional lane closures on Interstate 17 are scheduled during daytime hours between State Route 74 and Anthem Way. Northbound lanes will have restrictions from 6 a.m. to 2 p.m., while southbound lanes will be affected from 10 a.m. to 7 p.m., Friday through Sunday. ADOT urges caution in these work zones, reminding motorists to watch for workers and equipment.
In the Southeast Valley, Arizona Avenue and Lindsay Road will be closed in both directions at Loop 202 (Santan Freeway) from 10 p.m. Friday until 5 a.m. Monday for a widening project. Detours include McQueen, Cooper, and Gilbert roads as alternate cross streets. The westbound Loop 202 on-ramp at Arizona Avenue will also be closed; drivers can use the Alma School Road on-ramp instead.
“ADOT plans and constructs new freeways, additional lanes and other improvements in the Phoenix area as part of the Regional Transportation Plan for the Maricopa County region.”
Most current improvement projects receive funding from Proposition 400, a sales tax approved by Maricopa County voters in 2004. In November 2024, voters extended this funding by approving Proposition 479.
“Most improvement projects are currently funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004. Voters also approved Proposition 479 in November 2024, extending the existing half-cent tax to fund future transportation projects in the Phoenix region.”
Drivers can access real-time highway conditions through ADOT’s Arizona Traveler Information site at AZ511.gov, via the az511 app for Apple or Android devices, or by calling 511.
