Location: SR-71 at SR-91 Interchange

Construction: Long Range

Investment: Estimated $118 Million

Fact Sheet


Construct a two-lane direct flyover connector from eastbound State Route 91 to northbound State Route 71. Improve connection between the eastbound 91 Green River Road on-ramp and the 71/91 Interchange. Construct an eastbound road south and parallel to SR-91 between Green River Road and the 71/91 Interchange.

RCTC has received environmental approvals and is currently updating the project design, due to changes in Caltrans structure standards.  This estimated $121 million project is a major element of RCTC’s 10-year Measure A delivery plan and a high priority within the region. Project funding has been secured. Construction is expected to start in 2021, and the new lanes should open by 2023.

The 71/91 Interchange is a significant source of traffic congestion in the area, and this project is designed to reduce congestion, enhance safety of motorists, support movement of goods, and improve mobility and connections between State Route 71 and State Route 91 and among the counties of Riverside, San Bernardino and Orange.

The project will:

  • Replace the existing single-lane connection between eastbound SR-91 and northbound SR-71 with a new, two-lane, direct flyover ramp
  • Build a new, separate eastbound road just south of and parallel to SR-91 to provide improved access between the Green River Road interchange and the SR-91/SR-71 interchange.
