10:27 a.m. update: Traffic has cleared from the problem spots along State Route 347 and all affected roads have reopened.
Traffic on John Wayne Parkway in Maricopa could be heavier than usual for a while due to a traffic accident that closed the eastbound lanes of Interstate 10.
I-10 EB was closed at Riggs Road, south of Chandler, according to the Arizona Department of Transportation.
As a result, traffic was detouring around the accident scene via Riggs Road and State Route 347.
Eastbound Riggs Road was closed to traffic.
Casa Blanca Road also was closed at southbound SR 347 to eastbound traffic.
Southbound traffic on SR 347 is backed for more than a mile at the Casa Blanca light.
I-10 was reopened about 9:50 a.m., according to ADOT.
