91 Project Update
January 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 Starts "Main Street Squeeze"

The "Main Street Squeeze" began January 20 on Main Street in Corona for the 91 Project. Northbound and southbound travel on Main Street is reduced to two lanes in each direction between the westbound 91 ramps and Third Street. Also starting January 20, the eastbound on-ramp is closed for approximately 15 months. Motorists may use the Lincoln Avenue on-ramp as the detour, with the Magnolia Avenue or Hidden Valley Parkway on-ramps as alternate routes. 


The lane reductions and ramp closure will allow crews to rebuild the bridge, relocate utilities, lower the Main Street roadway, construct walls and widen sidewalks. In addition, Main Street will be widened at the request of the City of Corona to improve local traffic flow. Later this year, a full closure of the Main Street westbound off-ramp will be required for approximately 10-12 months.


At a later date, left turns onto the westbound on-ramp for northbound Main Street motorists may be restricted. Please click here to view detour map. 


More information will be provided in future Construction Alerts and other communication tools. Not registered to receive project information? Please use the "Contact Us" page of the website, call the helpline, 877-770-9191, "Like" us on Facebook or "Follow" us on Twitter. 


91 Project Reaches out to Emergency Responders

The Riverside County Transportation Commission hosted a briefing for emergency responders, transit operators and other local stakeholders on January 8 to provide a project update and overview of upcoming construction activity for the 91 Project.   


Representatives of law enforcement agencies, fire departments, medical personnel, school district staff, bus operators and waste management attended the briefing to learn about the upcoming "Main Street Squeeze" on Main Street. The briefing will help ensure that dispatchers are aware of the changes in local circulation to avoid interruptions of service. 


New Parking at Santa Ana River Trail

As part of the 91 Project, work is occurring near the Santa Ana River Trail (SART) along Green River Road in Corona and will continue through late 2015. Please note the SART will remain open during construction.

In late December, the parking area for SART users along Green River Road was removed and replaced with a new temporary parking area, just east of the Green River Golf Club entrance. This parking area will remain in place until a future permanent parking lot is constructed. Trail users should not park at the Green River Golf Club unless visiting the Golf Club.

The future permanent parking lot for SART users will be located west of the Green River Golf Club entrance. The new lot will include 56 ADA-compliant parking stalls, sidewalk, curb and drinking fountains. Please see the SART fact sheet for more details.

Trail visitors are encouraged to watch for construction workers and signage and drive safely through the area. 

For questions about the 91 Project or work near the SART, please call the helpline at 877-770-9191 or use the "Contact Us" page of the project website.


Business Support Program Meeting

The Riverside County Transportation Commission held its second Business Support Program for area business operators on January 16. Project representatives provided an overview of construction activity to date and explained details of the "Main Street Squeeze," which started January 20. Thank you to Corona Mayor Eugene Montanez and Corona City Councilmember Karen Spiegel for attending the event and participating in the discussion with businesses. Thank you, also, to Corona Public Works Director Nelson Nelson and Corona Chamber of Commerce Chief Executive Officer Bobby Spiegel for their involvement. 


Team members also promoted the "Shop Local. Shop 91" program, which provides incentives for supporting Corona-area businesses. For more information about the Business Support Program and the "Shop Local. Shop 91" program, please call the helpline, 877-770-9191 or visit the "Community & Business Support" section of the website.


91 Project Maintains Strong Safety Record

As of early December, the 91 Project did not have any reportable safety incidents among its project team members for 500,000 man-hours of work. This reflects a commitment to safe working practices by the team. Safety briefings, equipment inspections and a "see something, say something" culture is contributing to this top safety record.


The Riverside County Transportation Commission also reminds the public to drive safely within the 91 Project limits. Motorists are reminded to obey the 55 mile per hour speed limit, allow extra travel time, watch for changing conditions, avoid distractions and pay extra attention at night or during rainy weather.

Business Spotlight: Baker's Dozen Donuts

Baker's Dozen Donuts was established in 2003 by a dynamic married couple with a dream to say good-bye to corporate jobs and start a small business to serve their community the best donuts and pastries in town.

Located south of the 91 on Main Street, Baker's Dozen is a clean and fun place to purchase top quality and delicious maple bacon bars, tiger tails, banana fritters, and more. These sweet treats are actually famous. They've been featured on the PBS show, "IE Explorer," the "Inland Empire Hot List," and Inland Empire Magazine, just to name a few. They even make a GIANT glazed donut dubbed the "Happy Birthday Donut" for special celebrations.


Want to stop in for lunch? You're in luck. Baker's Dozen Donuts recently opened a deli full of sandwiches, salads, smoothies/iced frappes and shaved ice to enjoy. Baker's Dozen Donuts will be open for business during the 91 Project construction.
