FALCON Engineering Services (FALCON) is providing construction management services to assist the Riverside County Transportation Commission with “the 71/91 Interchange Project”. The 71/91 Interchange serves as a gateway between Riverside, Orange, and San Bernardino Counties and is a vital link for commuters and freight vehicles that travel along the 91 and the 71. The new non-tolled interchange is designed to improve safety, expand access to other modes of travel, reduce greenhouse gas emissions, and enhance traffic flow. The project will support continued movement through this area by native wildlife such as mountain lions, bobcats, and coyotes.


The project will:


  • Replace the existing single-lane loop connector between eastbound 91 and northbound 71 with a new, two-lane, direct connector ramp;
  • Build an eastbound 91 auxiliary lane to improve access to the new direct connector to northbound 71;
  • Realign the eastbound 91 on-ramps from Green River Road to improve access to the 71/91 Interchange;
  • Realign southbound 71 to create space for the new direct connector.
