"Main Push" Coming August 26-29 with Major Milestones
  • Completion of New Eastbound 91 Lincoln Avenue Ramps
  • Lane Shifts on 91 between the 15 and Maple Street
  • Full Closure of Westbound 91 at Maple Street

As part of the Riverside County Transportation Commission's (RCTC) 91 Project, a series of major milestones will be reached the weekend of August 26-29, 2016, keeping the project on track for opening new lanes in the first half of 2017.
 
With multiple construction activities scheduled on the 91 between Maple Street and I-15, motorists are advised to use alternate routes, such as the 60 or the 10, for east/west travel. Motorists also should allow extra travel time, carpool or use Metrolink, watch for changing conditions, follow detour routes, and check real-time traffic information using IE511.org. Nighttime consecutive on-ramp and off-ramp closures will occur Saturday on westbound 91 and Sunday on eastbound 91 within this area for lane shifts and restriping, prior to the Monday morning commute. The "Main Push" will include the following activities:
 
Completion of New Eastbound 91 Lincoln Avenue On-Ramp and Off-Ramp - Friday, August 26 at 9 pm to Monday, August 29 at 4 am
  • The old ramps will close permanently at 9 pm on Friday, August 26 to allow crews to complete the new ramps for opening at 4 am on Monday, August 29.
  • The new configuration has motorists exit and enter eastbound 91 on Second Street just east of Lincoln Avenue. This configuration provides improved access to and from the 91.
  • During the weekend closure, Second Street will be closed from Buena Vista Avenue to just east of the Cardenas Market's main entrance to finalize this connection.
Lane Shifts on Westbound and Eastbound 91 between the 15 and Maple Street - Saturday, August 27, from 10 pm to 8 am (westbound 91) and Sunday, August 28, from 9:30 pm to 6:30 am (eastbound 91)
  • During these nighttime closures, consecutive ramps will be closed in each direction in this area as crews shift all lanes on the 91 toward the outer shoulders.
  • Please use alternate routes if traveling at night. 
Full Closure of Westbound 91 at Maple Street for Bridge Demolition - Saturday, August 27 at 10:30 pm to Sunday, August 28 at Noon
  • A full closure of Westbound 91 at Maple Street will allow crews to demolish the north side of the remaining Maple Street bridge. Motorists traveling west on the 91 will exit at Maple Street, head north to Pomona Road, and then head west to Auto Center Drive to re-enter westbound 91.
  • Eastbound 91 will remain open during this bridge demolition work.
Closure and Demolition of Main Street Undercrossing between Ramps - Sunday, August 28 at 9 pm for Approximately Two Months
  • The Main Street undercrossing will be closed completely in both directions between the 91 ramps so that crews can build the center portion of the bridge over Main Street. See detour map below.
  • All of the Main Street ramps will remain open during the day. There will be periodic nighttime closures, which will be included in the weekly Construction Alerts.
  • During this time, motorists will have access to north/south travel on Main Street using West Grand Boulevard and East Grand Boulevard. Both of these streets will be open at full capacity and traffic signals will be optimized to reduce traffic delays.
  • To help emergency services respond to incidents, access will be provided beneath Main Street after demolition work takes place during the first week of the closure.
Opening of New Half of Maple Street Bridge - Monday, August 29 at 4 am
  • Maple Street over the 91 will be closed from Friday, August 26 at 9 pm to Monday, August 29 at 4 am. Motorists may use Smith Avenue or Serfas Club Drive for north/south travel during this weekend closure.
  • The first half of the new Maple Street bridge will open to motorists on Monday, August 29 at 4 am.
  • Once open, there will continue to be two northbound lanes with access to westbound 91 at Maple Street.
