91 Project Update
February 2015
Thank you for your interest in the Riverside County Transportation Commission's 91 Project. This monthly e-bulletin offers news and updates about this project, which is under construction in Corona and Riverside. For the latest information, please stay connected through the links below and the project helpline.
91 Project to Reduce Travel Lane on 

91-15 Connector in Corona on February 17

The 91 Project in Corona required the connector from the eastbound 91 to the southbound 15 to be reduced to one lane starting February 17 and will continue for approximately three months. Please click here for a map of the new lane configurations.


A full closure of the connector will be required from 10 p.m. to 5:30 a.m., February 16-19, for crews to place concrete barriers, known as K-rail. The lane reduction began the morning of February 17 to allow crews to make the tie-in to the new connector for this project. These dates are subject to change.


Motorists are reminded to: 

  • Slow down, watch for changing conditions and allow extra travel time, especially during peak afternoon and evening hours
  • Watch for changeable message signs about the upcoming lane reductions
  • Be courteous and merge to the single lane early to avoid unnecessary traffic delays
  • Adjust travel plans to off-peak hours, if possible, or use alternate routes
  • Carpool or use public transit, when feasible

Led by the Riverside County Transportation Commission, the 91 Project is adding regular lanes, tolled express lanes, auxiliary lanes and direct express lane connectors from the northbound 15 to the westbound 91 and from the eastbound 91 to the southbound 15. Improvements to interchanges, ramps, lanes and surface streets also will be made along the 91 between the Riverside County/Orange County Line in Corona and Pierce Street in Riverside.  The new lanes are expected to open in 2017.

Update on "Main Street Squeeze"

The "Main Street Squeeze" began January 20 with lane reductions on southbound and northbound Main Street and the closure of the eastbound on-ramp to the 91.  Two lanes will remain in place in both directions on Main Street through late 2016. The on-ramp is expected to reopen in spring 2016. 


The project team has been monitoring traffic flow and has made adjustments to the timing of traffic signals to improve travel through the area.   


Motorists should use the Lincoln Avenue on-ramp as a detour; the Magnolia Avenue and Hidden Valley Parkway on-ramps are alternate on-ramps. Please see the "91 Seconds on the 91" video for more information.

Bridge Reconstruction Begins at 

Buena Vista Avenue

The reconstruction of the Buena Vista Avenue undercrossing is under way. Crews demolished both sides of the bridge in early February, and daytime pile driving work will be is taking place from 7 am to 3 pm for approximately two weeks. On occasion, pile driving may occur outside the scheduled times, depending upon the schedule and field conditions. Residents should expect noise and vibration during this work.


Pile driving is a common method of building foundations to support a bridge. This activity requires large steel or concrete beams, referred to as "piles," which are pounded into the ground until they reach a hard layer of earth beneath the bridge foundation. For more information about pile driving operations, please click here to view the Pile Driving Frequently Asked Questions.


Sound walls on eastbound 91 near Buena Vista Avenue also are scheduled to be removed in February. New sound walls, ranging in height from 12 feet to 14 feet, will be constructed of tan, split-face block.


Bridge Demolition and Lane Reductions Occurring at West Grand Blvd.

Construction crews recently demolished sections of the West Grand Boulevard bridge, which is being followed by lane reductions on the undercrossing. Starting mid-February, West Grand Boulevard will be reduced to one lane in each direction between North Sheridan Street and Third Street. Traffic will shift to the middle of the roadway to allow crews to begin reconstructing the bridge. For questions or more information, please call the helpline at 877-770-9191 or use the "Contact Us" page of the project website.
