The South Mountain Freeway’s first new interchange at 40th Street has opened on schedule, an important step forward for the state’s largest-ever freeway construction project.
The interchange is ready for traffic less than four months after 40th Street closed south of Cottonwood Lane to allow construction of the new interchange.
At 92 feet wide, the interchange has nearly double the capacity of the previous intersection of 40th Street and Pecos Road. It will have two southbound lanes that will continue south of the freeway, two left-turn lanes to eastbound Loop 202 South Mountain Freeway, and a right-turn lane to westbound Loop 202. There also are two northbound lanes, with a left-turn lane to westbound Loop 202, and a dedicated northbound left-turn lane into the Park & Ride parking lot.
The fully functioning interchange includes ramps that will allow drivers to enter and exit the future freeway lanes in both directions. While construction continues, speed limits will remain at 40 mph on both future freeway lanes and the remaining sections of Pecos Road.
In addition, the Wild Horse Pass Hotel and Casino and the Phoenix Premium Outlets will be accessible either from I-10 and Wild Horse Pass Boulevard, or by taking 40th Street south to Willis Road.
The 22-mile freeway is scheduled for full completion in 2020, although traffic is expected to begin using the freeway earlier.
