RIVERSIDE, Calif. – The Riverside County Transportation Commission (RCTC) urges drivers to steer clear of eastbound 91 in Corona on Monday through Wednesday nights to avoid traffic delays. Full eastbound 91 closures for the 71/91 Interchange Project will begin on Monday, October 16 and continue through Tuesday, November 21.

Full closures will allow for the safe construction of support structures that will extend across the entire width of the 91. To achieve height clearance on the 91 roadway, the structures will reach approximately 30 feet high. Crews will also be placing beams across the 91 that will measure about 120 feet long and weigh 18 tons each. More than 200 beams will be placed over the freeway forming a tunnel- like structure which will be used to support the new bridge while it is being constructed.

Motorists traveling eastbound on the 91 should plan extra time to reach local destinations and businesses near the 71 and 91. To ensure the safety of motorists and construction crews, the project will require closures from Monday to Wednesday. 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 lane closures from Orange County/Riverside County Line to 15/91 Interchange 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.

To reduce time in traffic, motorists traveling eastbound are encouraged to avoid the area by using northbound 57 to eastbound 60 to southbound 71 as routes to get around the closure.

Drivers who need to reach Green River Road or choose to use the local detour should plan for heavy delays. Travelers may also use the eastbound 91 exit at Green River Road to Palisades Drive or Serfas Club Drive to re-enter the eastbound 91. Fire, police, and ambulance will have access 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.
