Full Nighttime Closures of 91 at Maple, Aug. 1-6
The 91 Project will require nightly full closures of the 91 at Maple Street this week. Eastbound 91 will be closed tonight from 10 pm to 5 am. Drivers will be directed to exit Maple Street and re-enter eastbound 91 at the Paseo Grande on-ramp or exit Maple and follow Sixth Street to El Sobrante Road, then head south to Magnolia Avenue, head east to enter I-15 and head north on I-15 to re-enter the eastbound 91. In addition to the closures occurring at Maple, nightly closures of the 91 at I-15 are continuing. Motorists who plan to travel east of I-15 on the 91 should use the second detour route.

Main Street Undercrossing to Close for Two Months

The final phase of the "Main Street Squeeze" will begin in late August with a two-month closure of the Main Street undercrossing. On or about Monday, August 29, crews will close Main Street between the eastbound and westbound ramps through late October to replace the "middle" bridge over Main Street. The bridge replacement will allow new lanes to be added to Main Street for greater capacity.

Motorists will be directed to use E. Grand Boulevard, Third Street, Sixth Street, W. Grand Boulevard and Lincoln Avenue as alternate routes. All four of the Main Street ramps will remain open, with only right turns permitted from the off-ramps.

To prepare for the closure, modifications will be made to the eastbound on-ramp and off-ramp at Lincoln Avenue, requiring a weekend full closure of these ramps in mid-August. Traffic signals will be optimized along the detour route for improved traffic flow, and the signal at Joy Street/E. Grand will be completed. During the weekend of August 27, a series of lane closures and ramp closures will be required between I-15 and Maple Street to support the Main Street work. Additional signs will be placed to direct motorists to detour routes and to access local businesses. Please watch for updates and detour maps.

The decision to conduct a full closure was made after considering the results of a traffic study, obtaining input from area businesses, discussing options with emergency responders and comparing the construction time required for a full closure versus only nighttime closures of the undercrossing. With a full closure, crews are expected to complete the work within two months; limiting the closures to nighttime hours would have required 3.5 months of work.

A briefing will be held for emergency responders on August 23 to provide detailed information. Emergency access will be provided following the first week of the closure, once bridge demolition is complete.

Pile driving work, which generates loud, repetitive noise, is scheduled for approximately one month, as late as 10 pm. Pile driving is a common method of constructing foundations to support a bridge. This activity requires large beams, referred to as "piles," to be pounded into the ground until they reach a hard layer of earth beneath the bridge foundation.

During the closure, motorists are advised to be prepared and allow extra travel time to drop off and pick up students from school, to attend appointments at the Corona Regional Medical Center, or to access the Metrolink North Main Corona station. Businesses will be open during the undercrossing closure. Remember to patronize local businesses and visit the "Shop 91. Shop Local." page to download great money saving coupons.
