Southern Avenue bridge construction to require overnight closures

June 11, 2018

PHOENIX – The next phase of construction on a Southern Avenue traffic interchange for the Loop 202 South Mountain Freeway will require overnight closures this week and at other points over summer.

Southern Avenue between 61st Drive and 59th Avenue in Laveen will close nightly from 8 p.m. to 5 a.m. Tuesday through Friday, June 12-15, to place 16 steel-reinforced concrete girders that span 122 feet and weigh more than 110,000 pounds each.

Additional overnight closures will be needed over the next few months so Connect 202 Partners, builder of the South Mountain Freeway, can install deck panels and pour the concrete deck for the bridge.

Drivers should consider alternate routes, including Baseline and Broadway roads, to travel east-west between 51st and 67th avenues during these overnight closures.

The Southern Avenue interchange, which will include a 125-foot-long overpass, is one of 13 interchanges planned for the 22-mile freeway, the longest single highway project ever undertaken by the Arizona Department of Transportation.
