91 Project Update
November 2014

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 started construction in Corona and Riverside. For the latest information, please stay connected through the links below and the project helpline.

Pile Driving Completed Near Prado Bridge

As part of the Riverside County Transportation Commission's 91 Project, a new bridge is being built over Prado Road near Green River Road. Crews recently completed pile driving for the foundations of the new bridge. Pile drilling work is expected to be completed within the next several weeks for this phase of work. Please note that nighttime noise has been reduced by changing work methods and by scheduling less work at night.


Due to concerns voiced by residents, the project team has reduced work hours. Although Caltrans allows work to exceed 86 decibels from 6 am to 9 pm, the team has scaled back the hours for this noisiest work to 7 a.m, to 8 p.m., Monday through Saturday, and 10 a.m. to 6 p.m. on Sundays.


The team also has implemented a number of other measures to keep noise to the 60 to 70 decibel range at night. Project staff is monitoring noise levels nightly and exploring ways to further reduce noise.


Current activities for the new Green River Road off-ramp are expected to be complete next summer. Traffic then will be switched to the new ramp, making way for the 91 to be widened. The overall project will be completed in 2017.


The team appreciates the patience of local residents and is continuing to respond to concerns. Please direct questions to the project helpline, 877-770-9191 or the "Contact Us" section of the website, sr91project.info.

Main Street Bridge Demolition


In the coming weeks, crews will be gearing up for nighttime street and ramp closures to allow for removals of the north and south sides of the Main Street Bridge in Corona. Detour routes will be posted and in place for drivers heading north and south on Main Street. Pedestrian access also will be closed during the nighttime activities. The eastbound 91 off-ramp will remain open during the closures, but the eastbound on-ramp, westbound off-ramp and westbound on-ramp will be closed at night.


Specific dates and detour routes will be posted as this work draws closer. For additional information, please call the project helpline, 877-770-9191, use the "Contact Us" page of the website, "Like Us" on Facebook or "Follow" us on Twitter.

Construction is in full swing, with crews gearing up to start work throughout the project limits. Residents, businesses and motorists can expect to see the following work under way in the months ahead:

  • Demolition of bridges on Main Street, Buena Vista Avenue and W. Grand Boulevard
  • Removal of sound walls, including those between Maple Avenue and Grand Boulevard, between Grand Boulevard and Main Street, and along Green River Road and Serfas Club Drive
  • Continued work along Green River Road and near the Santa Ana River Trail (see story above)
  • Full closure of Main Street ramps for approximately one year

Freeway Service Patrol to Expand for 91 Project


Flat tire? Dead battery? The Freeway Service Patrol (FSP) is here to help. The Riverside County Transportation Commission (RCTC) operates a fleet of roaming tow trucks along the 91 during weekday peak commute periods to help stranded vehicles. As part of the 91 Project, service hours will be extended in areas where shoulder widths has been reduced.


Friendly FSP operators can jump-start a dead battery, change a flat tire, provide a gallon of gas and offer other minor mechanical assistance or towing to a CHP-approved location. FSP assistance is offered to motorists at no charge.


FSP currently operates on the 91 in both directions between the Orange County line and Interstate 15. Extended service hours will begin in November on the 91 between the 71 and the Riverside County/Orange County line, due to reduced shoulder widths. Current service hours include: 


91 Corridor

Westbound 91 near Main Street Area Only

5:30 am - 8:30 am, Monday - Friday

8:30 am - 3 pm, Monday - Thursday

3 pm - 7 pm, Monday - Thursday

8:30 am - 1 pm, Friday

1 pm - 7 pm, Friday

6:30 am - 10 pm, Saturday


8:30 am to 9:30 pm, Sunday


In case of a vehicle breakdown, never cross lanes to find help. Wait for the FSP or CHP to summon help. All FSP trucks are white and display the FSP logo (shown in the photo above). Drivers wear blue uniforms and safety vests with the same logo. All FSP drivers wear an ID badge on their shirts and are certified by the CHP.


Business Spotlight: 

ARCO and McDonald's


Running on empty? Consider heading to ARCO, south of the 91 at Serfas Club Drive in Corona. Arco is a great choice to fill up on gas, including diesel, get a car wash and pick up snacks. All grades of gas are competitively priced, and McDonald's is right next door, making it convenient to fuel up with two all-beef patties, special sauce, lettuce and the rest of the good stuff. Arco and McDonald's have been fixtures in Corona for years, and rest assured, they will remain open during construction. Don't let intermittent closures on Serfas Club detour you from these local businesses.
