Riverside SR 91 lane closures

RIVERSIDE, Calif. Nighttime drivers should plan for closures on the Riverside Freeway (State Route 91) at the La Sierra Avenue interchange Friday and Saturday to remove the old La Sierra bridge over the freeway.

• All eastbound SR 91 lanes and westbound SR 91 HOV lane and No. 1 lane will close Friday night, (Sept. 12), 11 p.m. through Saturday morning, (Sept. 13), 9 a.m.
• All westbound SR-91 lanes and eastbound SR 91 HOV lane and No. 1 lane will close Saturday night, (Sept. 13), 10 p.m. through Sunday morning, (Sept. 14), 9 a.m.

During the closures, traffic will be detoured off the freeway onto the La Sierra Avenue exit and then immediately back onto the Riverside Freeway using the on-ramp. California Highway Patrol and Freeway Service Patrol will be there to assist and ease congestion.

La Sierra Avenue over the freeway will remain open during construction, although delays are expected. All businesses will remain accessible. Drivers should use alternate routes, such as Pierce, Magnolia or Tyler Streets, during the closures.

The $38 million project will replace the La Sierra Avenue bridges over both the freeway and the railroad tracks with six-lane bridges to reduce traffic congestion. New dual left-turn lanes onto the freeway will make it easier for vehicles to access the Riverside Freeway, while ramps will be widened from two to three lanes.

The project is expected to be completed by the summer of 2009.
