As the reconstruction project at the interchange connecting State Route 71 and 91 Freeway continues in the Inland Empire, a portion of the 71 Freeway will be fully closed over the weekend, the Riverside County Transportation Commission announced.
The closure will affect southbound lanes of the 71 Freeway at Butterfield Ranch Road/Euclid Avenue in Chino Hills from Friday, Aug. 16 at 10 p.m. through Monday, Aug. 19 at 5 a.m.
The southbound lanes of the 71 to the eastbound and westbound lanes of the 91 Freeway connectors will also be closed.
“This closure is required to allow crews to safely pave and stripe the final portion of the newly aligned southbound 71 lanes to shift traffic onto the new lanes,” the Riverside County Transportation Commission said.
