91 Project
 Date: August 29, 2016
Thank You, Motorists, Corona Community, and Crews!
August 26-29 "Main Push" Complete

The 91 Project's "Main Push" effort concluded this morning, resulting in a series of major milestones. The Riverside County Transportation Commission thanks the motorists and Corona community members, who heeded warnings about planned construction activity and avoided the area as much as possible, and thanks our hard working construction crews, whose efforts will keep the project on track for opening the new lanes during the first half of 2017.
Please note the following:
  • Eastbound and westbound 91 lanes have shifted toward the outer shoulders. For your safety and the safety of our crews, please note the new alignment and watch for crews working in the median. Lanes also have been restriped to improve visibility.
  • The new eastbound Lincoln Avenue ramps opened this morning with connections to Second Street. This new alignment improves access to and from the 91.
  • Demolition of the north side of the remaining Maple Street Bridge completed early Sunday. The first half of the new Maple Street Bridge opened this morning with two lanes for northbound travel only and will remain in that condition for several more months.
  • Main Street beneath the 91 closed Sunday night for bridge demolition and will remain closed for about two months to build the center portion of the bridge. Ramps will remain open during the day. From the off-ramps, motorists must turn right and can use W. Grand Boulevard and E. Grand Boulevard as detours. (Please see detour map below). A new traffic signal has been placed at E. Grand and Joy Street, and other signals have been optimized to promote traffic flow. Emergency responder access will be provided beneath Main Street after Labor Day.
  • Roadway alignments will continue to change. Please watch for changing conditions and remember that the speed limit is 55 MPH within the project limits. Also, please allow extra travel time, especially with school back in session. If possible, carpool or use Metrolink. Before starting your commute, check the website, Facebook or Twitter for Construction Alerts or use IE511 for real-time traffic information.
