Project Status: PRE-CONSTRUCTION


Location: State Route 71/State Route 91 Interchange, Corona

Construction: Dependent upon funding; could begin in late 2019

Investment: $121 million (construction)

OVERVIEW


The Riverside County Transportation Commission, in partnership with Caltrans, has received project approvals and has completed final design for the State Route 71/State Route 91 (71/91) Interchange Project in Corona. RCTC is actively seeking funding to improve this congested and operationally deficient interchange.

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 State Route 91. The new interchange is designed to reduce congestion, enhance travel reliability, improve traffic safety, and reduce pollutants and emissions.

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 a new, separate eastbound auxiliary lane from Green River Road to east of the 71/91 interchange; and
  • Realign the eastbound 91 on-ramp from Green River Road to improve access to the 71/91 interchange.

Caltrans approved the environmental document in June 2011, and RCTC completed final design for the project in June 2015. RCTC is actively seeking funding to build the estimated $121 million project. Funding could include federal, state and local sources.

Once RCTC receives funding, construction could begin in late 2019 and be completed in about three years. Construction likely would occur in stages to minimize disruption to motorists through this heavily traveled corridor.

  • June 2011: RCTC receives final approval of environmental documents
  • October 2013: Final design begins (project plans, specifications and cost estimates)
  • June 2015: RCTC completes final design
  • 2018 and 2019: RCTC seeks funding through the state SB 1 Congested Corridors Program, federal Better Utilizing Investments for Leveraging Development (BUILD) Program, and federal Infrastructure for Rebuilding America Program
  • Mid 2019: Advertising for construction contractor could begin, pending receipt of project funding
  • Late 2019: Contract award anticipated, pending receipt of project funding
  • Late 2022: New interchange expected to open
