Traffic Alerts

Southbound Loop 101 restricted between Cactus Road and 90th Street

Improvement projects will require restrictions, including ramp closures, along Phoenix-area freeways this weekend (April 29-May 2). Project schedules are subject to change due to inclement weather. The Arizona Department of Transportation recommends planning ahead and considering alternate routes while the following scheduled restrictions are in place:

Southbound Loop 101 (Pima Freeway) narrowed to three lanes (right lanes closed) between Cactus Road and 90th Street from 10 p.m. Friday to 5 a.m. Sunday (May 1) for rubberized asphalt paving. Southbound Loop 101 on-ramp at Cactus Road, off- and on-ramps at Shea Boulevard and off-ramp at 90th Street closed. DETOUR: Please plan to use alternate ramps in area, including those at Raintree Drive and Via de Ventura.

ADOT plans and constructs new freeways, additional lanes and other improvements as part of the Regional Transportation Plan for the Maricopa County region. The primary funding source for regional freeway improvements is a half-cent sales tax approved by county voters in 2004. More information about ADOT projects and the regional plan is available at
