Board Approves Contract for I-10 Cedar Ave Interchange

October 13, 2020

The SBCTA Board approved a Construction Management Services contract for the Interstate 10 (I-10) Cedar Avenue Interchange Improvement Project. The $10.3 million contract was awarded to WSP USA, Inc.

The I-10 Cedar Avenue Interchange is the highest priority in the Measure I 2010-2040 Freeway Interchange Program. The interchange, located in the community of Bloomington, is critically needed as the location experiences high levels of traffic congestion resulting in low levels of service for commuters. Reconstruction of the interchange includes widening the I-10 overcrossing, replacement of the railroad bridge, roadway improvements along Cedar Avenue from Bloomington Avenue to Slover Avenue and adding capacity to the ramps.

Total project cost is approximately $110 million. The I-10 Cedar Avenue Interchange was environmentally cleared in 2013. Final design is anticipated to be complete in Summer of 2021 with construction beginning in early 2022 and project completion in 2024.
