A full closure of eastbound and westbound 91 between the 71 and I-15 will occur from Friday, Feb. 19, 2016 at 9 pm to Monday, Feb. 22, 2016 at 4 am.  This 12-mile stretch of freeway sees over 280,000 cars per day, and that number is expected to jump to 425,000 by the year 2030, according to Joel Zlotnik of the Orange County Transportation Authority.

The 91 freeway is a valuable transportation corridor for thousands of motorists, and also serves hundreds of thousands of commercial and freight trucks as they travel inland from the ports of Long Beach and Los Angeles, according to Anaheim City Councilman Harry Sidhu.

The full weekend closure of the 91 will allow crews to perform three major construction activities: 1) Demolish the west side of the Maple Street Bridge over the 91; 2) Install support beams for the new westbound Maple Street flyover ramp bridge; and 3) Pave the new eastbound 91 alignment near I-15.

“By fully closing the roadway, we will be able to consolidate these significant construction efforts into one weekend, rather than multiple weekends or extending this over a month of weeknights,” said RCTC Executive Director Anne Mayer. “Consolidating the work activities within one weekend will reduce the number of closure hours by more than 50 percent. The project’s design-build method allows for flexibility in planning work, such as this weekend closure,” she said. Another benefit, Mayer noted, is that the full closure will help ensure the safety of the 91 Project crews and the traveling public by eliminating cars and construction equipment on the road at the same time.

More work will be occurring in the Maple Street area during the coming months, including reconstructing the Maple Street bridge and building the flyover connector ramp bridge. Crews will require nightly full closures of eastbound 91 for about a week after the weekend closure. During these closures, motorists will be directed to the eastbound 91 Maple Street off-ramp, and then east on Frontage Road to re-enter the 91 at the Maple/Paseo Grande on-ramp. Once the flyover ramp bridge is completed this summer, another full closure of the 91 may be conducted to remove the temporary support beams that will be placed the weekend of February 19-22.

Because of the impact that a full closure will have on this heavily traveled roadway, motorists are urged to “steer clear” of the area during this closure. To minimize major travel delays and impacts during the closure, RCTC strongly recommends that motorists plan ahead, avoid travel in the area or stay home. Motorists traveling on the 91, the 71 or I-15 near the project area during the closure period can expect travel delays of three to four hours. If travel cannot be avoided, motorists can use the 57, 60 and I-10 as alternate routes.

The Green River Road interchange will remain open to motorists, and during the weekend closure, emergency vehicles will be able to travel on the 91, as needed, to respond to police, fire and medical situations.  “Corona residents can rest assured that police, fire, CHP and ambulance personnel will be fully briefed about the weekend closure and are ready to respond,” Mayer said.

In case of rainstorms or inclement weather, the closure will be postponed to the next weekend, weather permitting.  For more information, please call the helpline at 877-770-9191, or visit
