15/91 Express Lanes Connector

Status: Pre-Construction

Location: Western Riverside County

Type of Project: Highways

Location: Interstate 15 and State Route 91, Corona

Construction: Planned to begin in the fall of 2020; anticipated opening in 2023

Investment: $270 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. 

The Commission awarded a design-build contractor in March 2020.

Construction is planned to begin in fall of 2020, and the connector is expected to open in 2023.
