As part of the Riverside County Transportation Commission’s (RCTC) 91 Project, there will be a 55-hour weekend full closure of the 91 in both directions between the 71 and I-15 in Corona from Friday, February 19 at 9 pm to Monday, February 22, 2016 at 4am.

This closure, branded “91 Steer Clear,” is needed to perform three major construction activities:

By fully closing the roadway, these significant construction efforts can be consolidated into one weekend, rather than multiple weekends or extending this over a month of weeknight closures. The full closure also will help ensure the safety of construction crews and the traveling public by eliminating cars and construction equipment on the road at the same time.

To minimize travel delays and impacts during the closure, RCTC strongly recommends that motorists plan ahead and completely avoid travel on and near the 91 in Corona or stay home. If travel cannot be avoided, motorists can use the 57, 60 and I-10 as alternate routes. Motorists traveling on the 91, 71 or I-15 near the project area during the closure period can expect delays of three to four hours. Please see detour map below.

A public meeting, focused on local impacts, will be held Saturday, Feb. 6 from 9 am to noon at the Corona Public Library, 650 S. Main Street, Corona to provide more information about the closure. Presentations will be held at 9:30 am, 10:30 am and 11:30 am; the presentation will be the same each time. A webcast option will be available for those who are unable to attend in person. To participate online, go to www.ustream.tv/channel/Rm9qrcU69JR. In addition, a link to a video recording of the meeting presentation will be provided after the meeting. In case of rainstorms or inclement weather, the Feb. 19-22 closure will be postponed to the next weekend, weather permitting.

Once the weekend construction activities are completed, more work is on the way for the Maple Street area during the coming months. Crews will rebuild the Maple Street bridge and construct the flyover ramp bridge across the 91. Nightly full closures of eastbound 91 likely will be required for about a week following the full weekend closure; additional periodic nighttime closures will occur in the future. Once the flyover ramp bridge at Maple Street is completed this summer, another full closure of the 91 may take place place to remove the temporary support beams that will be placed the weekend of Feb. 19-22.
