The Point: Closures will allow crews to safely remove support structures above the eastbound 91

Traveling through Corona at night this summer? There are road closures in the works that you should know about. Motorists driving on the eastbound 91 Monday through Wednesday nights should plan ahead for traffic delays. Starting Monday, July 15, weeknight closures of the eastbound 91 general purpose lanes and Express Lanes are scheduled as part of the 71/91 Interchange Project in Corona. The eastbound Green River Road on-ramp will also be closed at night.

Closures are as scheduled:

  • LOCATION: Eastbound 91, from Green River Rd. to Serfas Club Dr./Auto Center Dr.
    • Includes eastbound 91 general purpose lanes, Express Lanes, and Green River Rd. on-ramp
  • DAYS & TIMES: Nightly, Monday through Wednesday from 11:00 p.m. to 5:00 a.m.
  • DURATION: July 15 – August 14, 2024

The southbound 71 connectors to eastbound and westbound 91 will remain open.

The closures will allow crews to safely remove support structures above the eastbound 91 that were constructed in 2023 and early 2024. These support structures were used to form the foundation of the new connector. The removal process will take place over several weeks, Monday through Wednesday nights, beginning July 15.
