SR 152 Trade Corridor

Project Description

Santa Clara and San Benito counties are working together (Mobility Partnership) to develop and deliver infrastructure improvements to the SR 152 Trade Corridor from U.S. 101 to I-5. VTA, in coordination with the California Department of Transportation (Caltrans) is leading the development of this project.

This project includes the realignment of SR 152 between U.S. 101 and SR 156, and the eastbound truck climbing lanes over Pacheco Pass. The improvements would accommodate the long-term travel needs of commercial, commuter, and recreational traffic and result in an economically viable, safe, and efficient highway system that would enhance the quality of life for the local communities and economic vitality of the region.
