Southern Avenue interchange progressing, closure to be lifted next month
PHOENIX – After moving more than 450,000 cubic yards of earth, enough to fill up 150 Olympic-size swimming pools, construction on the Southern Avenue traffic interchange for the South Mountain Freeway remains on track to reopen Southern next month between 61st Avenue and 64th Place in Laveen.
The closure of Southern Avenue that began Nov. 27 has allowed crews to safely move this large amount of dirt without having to cross local traffic and has accelerated construction of the southern half of the interchange as the Arizona Department of Transportation moves even closer to opening the 22-mile freeway by late 2019.
In addition to the extensive earthwork, crews have completed substantial work that isn’t visible as it occurred below grade, including installing underground utilities and drainage structures. Above ground, crews have built bridge columns and retaining walls that will support a 125-foot-long bridge and have removed the existing roadway.
Today, crews started work to pave the eastbound lanes that motorists in both directions will share until the westbound lanes are built at a later date.
After the Southern Avenue closure is lifted, additional work will include paving the ramps and mainline freeway, installing signage, constructing retaining walls, finishing construction of the Southern Avenue bridge, completing final striping and adding landscaping.
