The Point: Closures will allow crews to safely continue construction of new connector formwork and support structures

Heading out of the Inland Empire on weeknights? Motorists are advised to stay alert for full westbound 91 closures between State Route 71 and Green River Road in Corona. Following the successful weeknight closures of eastbound 91 during October and November, full closure of westbound 91 will take place Monday through Wednesday nights starting on December 11 through January 24, 2024.

Due to the holidays, no closures will be scheduled from December 22 through January 1, 2024. Nighttime closures will resume on Tuesday, January 2, 2024.

The westbound 91 closures are needed to allow crews to safely construct support structures extending across the entire width of the 91 as part of RCTC’s 71/91 Interchange Project. The support formwork on top of the tunnel for the new connector will be approximately 30 feet in height with over 200 beams being positioned during these weeknight closures.

Access will remain available for fire, police, and ambulance units in case of emergency response. Construction activity is subject to change due to weather or unforeseen circumstances.

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.
