Freeway improvement projects will cause closures and lane restrictions in two areas of metro Phoenix this weekend, according to the Arizona Department of Transportation (ADOT). Drivers are advised to allow extra travel time and use detour routes while these restrictions are in effect from March 6 to March 9.
Eastbound Loop 202 (Santan Freeway) will be closed at Val Vista Drive in Gilbert from 6 p.m. Saturday until 8 p.m. Sunday for a widening project. On-ramps at Cooper, Gilbert, and Lindsay roads will also be closed. Eastbound traffic can use the off- and on-ramps at Val Vista Drive as a detour, or consider alternate routes such as eastbound Williams Field or Germann roads. Lindsay Road will be closed in both directions at Loop 202 from 10 p.m. Friday to 3 p.m. Saturday and again from 9 p.m. Sunday to 5 a.m. Monday.
On Loop 101 (Agua Fria Freeway), both east- and westbound off-ramps at 75th Avenue in the Northwest Valley will be closed from 10 p.m. Friday to 6 p.m. Sunday for another widening project. Additionally, 75th Avenue will be closed near Loop 101 in both directions during this period. Westbound drivers can exit at 67th Avenue, while eastbound drivers may use Union Hills Drive or 59th Avenue as alternatives. Those who typically use 75th Avenue near Loop 101 should consider using either 67th or 83rd avenues.
ADOT notes that restriction schedules could change due to weather or other factors.
According to ADOT’s official website, the department manages facilities including rest areas, snowplow operations with specialized equipment, and highway cameras for monitoring road conditions across Arizona.
The freeway improvements are part of the Regional Transportation Plan for Maricopa County, which is funded by Proposition 400—a dedicated sales tax approved by voters in 2004—and by Proposition 479, passed in November 2024, which extends the existing half-cent tax for future transportation projects.
“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 improvement projects currently receive funding through these propositions:
“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.”
Real-time highway conditions can be accessed on ADOT’s Arizona Traveler Information site at AZ511.gov, through the az511 app available for Apple or Android devices, or by calling 511.
