The Point: Avoid the area or buckle up for heavy delays, Friday night to Monday morning

Another full closure of eastbound 91 in Corona is set for Friday, September 30 at 10 p.m. to Monday, October 3 at 5 a.m. to allow crews for RCTC’s 91 Refresh Project to continue to repave lanes.

All eastbound 91 lanes will be closed from Main Street to just west of Interstate 15 throughout the weekend. The eastbound 91 Express Lanes and the eastbound 91 Main Street on-ramp also will be closed. The 15/91 Interchange will remain open.

The closure is needed for the safety of motorists and crews while the paving work is under way. This work follows the full closure of eastbound 91 in this same area on September 16-19; crews will be replacing temporary asphalt with permanent concrete to give motorists a smoother ride.

Steer clear by using Routes 60, 71, or 57 or Interstates 15 or 215 as alternate routes. Those who must travel on eastbound 91 should expect significant delays and use the northbound/southbound I-15 connectors as shown on the detour map below.

  • From southbound I-15, exit at Magnolia Ave., enter northbound I-15, and use the 15/91 connector to eastbound 91.
  • From northbound I-15, exit at Hidden Valley Pkwy., enter southbound I-15, and use the 15/91 connector to eastbound 91.

The 91 Refresh Project is a partnership between RCTC and Caltrans to repave lanes and repair sound walls and concrete barriers along the outer portions of eastbound and westbound 91 in Corona. Work will occur mainly between the Lincoln Avenue interchange and Interstate 15, an area with a long history of roadway settlement. Construction will take place through the fall, with more weekend closures to be announced.

Construction activity is subject to change due to weather, staffing, or other factors. If the repaving cannot be completed this weekend, it will be rescheduled as soon as possible.
