91 corridor improvement Project

Construction of this innovative design-build project began in mid-2014; the new 91 Express Lanes and regular lanes opened on March 20, 2017. The project added regular lanes, extended the 91 Express Lanes to Riverside County from Orange County, added auxiliary lanes and constructed express lane connectors from northbound 15 to westbound 91 and from eastbound 91 to southbound 15. Improvements to interchanges, ramps and surface streets also were made along the 91 corridor.

AA was responsible for providing support to RCTC’s program and construction outreach. AA also provided guidance to the design-builder’s public outreach staff to ensure consistent messaging and to approve draft Construction Alerts, videos, detour maps, social media posts, and other materials. For the 91 Project, RCTC conducted periodic full closures of the roadway, including a weekend full closure of eastbound and westbound 91 in February 2016. AA helped coordinate a robust, award winning “91 Steer Clear” outreach campaign to divert motorists from the 91 for a full weekend. The campaign featured multiple news conferences, radio advertising, billboards, social media campaigns, and ongoing coordination with Caltrans, emergency responders, and neighboring jurisdictions in Riverside County and Orange County.
