15/91 Express Lanes Connector

Status: Construction

Location: Corona

Type of Project: Express Lanes

Location: Interstate 15 and Route 91, Corona

Construction: April 2021; anticipated opening in 2023

Investment: $270 million


RCTC, in partnership with Caltrans, is building the 15/91 Express Lanes Connector, which will link the 15 Express Lanes to the 91 Express Lanes. A new connection will be provided from the eastbound 91 Express Lanes to the northbound 15 Express Lanes and from the southbound 15 Express Lanes 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 residents of Corona, Norco, Jurupa Valley, Eastvale, and points north in San Bernardino County, as well as express buses. The project also will extend both the eastbound 91 outside general purpose lane and the eastern end of the 91 Express Lanes approximately one-half mile east to Promenade Avenue to help with vehicle merging in this area.

The project will:

  • Reduce congestion and improve traffic operations
  • Enhance safety
  • Create a seamless transition and increase travel time reliability between these two tolled systems

The project is fully funded, and RCTC awarded a design-build contract in April 2020. Construction began in April 2021. The connector is anticipated to open in 2023.

Construction began in April 2021, and the connector is expected to open in 2023. During construction, four single-direction weekend closures of the connectors are planned, as well as periodic nighttime lane closures of the connectors and on Route 91.
