The Point: Closures allow crews to safely construct new connector formwork and support structures across the entire width of the 91

Motorists heading east should steer clear of eastbound 91 in Corona or plan for heavy traffic delays due to full eastbound 91 closures Monday through Wednesday nights starting Monday, October 16 through Tuesday, November 21.

Closures allow crews to safely construct support structures extending across the entire width of the 91 as part of the 71/91 Interchange Project. Support formwork for the new connector on top of the tunnel will be approximately 30 feet tall and utilize over 200 beams that will be positioned.

The weeknight closures include:

  • Full eastbound closure of 91 lanes from Green River Road to Serfas Club Drive, Monday through Wednesday from 11 p.m. to 5 a.m.
  • Full eastbound 91 Express Lanes will be closed in Riverside and Orange counties from Monday – Wednesday 10 p.m. to 6 a.m.
  • Eastbound on-ramp closure at Green River Road from Monday – Wednesday 10 p.m. to 6 a.m.

During the weeknight closures, motorists can reduce time in traffic by using northbound 57 to eastbound 60 to southbound 71. Please use caution during travel and plan extra time to arrive to your destination. The suggested detour route is shown below.

West Corona residents may utilize the eastbound 91 exit at Green River Road to Palisades Drive or Serfas Club Drive to re-enter to eastbound 91. Access will remain available for fire, police, and ambulance for emergency response.

Construction activity is subject to change due to weather or unforeseen circumstances. Weeknight westbound 91 full closures are expected to begin following the completion of the eastbound support structure work.

The 71/91 Interchange began construction in February and the anticipated opening of the connector is slated for 2025. This project will create a two-lane direct connector between eastbound 91 and northbound 71 to replace the existing single-lane loop connector. This enhancement is intended to improve safety, develop alternative modes of transportation, reduce greenhouse gas emissions, and optimize traffic flow. The $137 million investment is providing 1,677 jobs during construction.
