Location: Interstate 15 and State Route 91, Corona

Construction: Planned to begin in fall 2020; anticipated opening by end of 2022

Investment: $220 million


The Riverside County Transportation Commission, in partnership with Caltrans, is preparing to build the 15/91 Express Lanes Connector, which will link the future 15 Express Lanes currently under construction to the 91 Express Lanes. A new connection will be provided from the eastbound 91 Express Lanes to the future northbound 15 Express Lanes currently under construction and from the future southbound 15 Express Lanes currently under construction to the westbound 91 Express Lanes.

The 15/91 Express Lanes Connector is designed to provide a seamless transition between these Riverside County tolling systems for reliable, convenient travel for Eastvale, Jurupa Valley, Norco and Corona residents and express buses.

The project will:

  • Allow a seamless transition for motorists between the existing 91 Express Lanes and future 15 Express Lanes
  • Reduce congestion and improve traffic operations
  • Enhance safety
  • Increase travel time reliability

RCTC received $180 million in funding from Senate Bill 132 and has committed to fund the remaining balance with excess toll revenue from the operating 91 Express Lanes. RCTC is also seeking federal funds to build this direct connector.

The Commission expects to select a design-build contractor in early 2020.

Construction is planned to begin in fall 2020, and the connector is expected to open by the end of 2022.

  • 2017: RCTC receives $180 million in funding from Senate Bill 132 and the Commission approves amending existing contracts and/or pursuing new contracts to expedite project delivery
  • 2018: RCTC develops preliminary design and environmental studies
  • 2019: Commission approves funding gap and staff begins procurement for a design-build contractor

RCTC anticipates that the Supplemental Project Report and Environmental Revalidation documents will be approved in mid-2019 and will upload these files once completed.
