I-10 weekend, overnight closures ramping up for South Mountain Freeway
Crews completing interchange as Loop 202 construction advances
As the Loop 202 South Mountain Freeway interchange with Interstate 10 emerges in west Phoenix, construction of the remaining ramps will require several weekend and overnight closures of I-10 during the first half of 2019, according to the Arizona Department of Transportation.
While there have been many weekend and overnight traffic restrictions on I-10 since major construction began on the South Mountain Freeway in 2017, the frequency of closures will pick up over the next several months as Connect 202 Partners, the developer of the 22-mile freeway, moves toward completion of the state’s largest single highway project ever.
The first such closure of 2019 is scheduled for this weekend, when eastbound I-10 will be closed between 67th and 43rd avenues from 9 p.m. Friday, Jan. 18, to 5 a.m. Monday, Jan. 21.
During these closures, crews will complete flyover ramps for HOV lanes and the connection between westbound I-10 and southbound Loop 202. Because portions of these structures span the width of I-10, construction can’t occur with traffic underneath.
Eastbound I-10 switched to new lanes at Eloy Monday night, Jan. 14
Eastbound traffic on Interstate 10 in Eloy has moved to new pavement that took place Monday night, another important step forward for the $58 million project widening 4 miles of I-10 between Tucson and Phoenix.
eastbound traffic has been re-routed to the future westbound lanes and will remain that way for about the next four months, separated from westbound traffic by concrete barrier, while Arizona Department of Transportation crews build new eastbound lanes.
Tuesday, ADOT crews reopened State Route 87 between I-10 and Milligan Road and opened three ramps connecting with SR 87 – the westbound I-10 on- and off-ramps and a temporary eastbound off-ramp. Drivers exiting I-10 will only be able to drive north on SR 87.
