State Route (SR) 152 New Trade Corridor Project

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

This project proposes to construct a new 4-lane highway between U.S. 101 and SR 156 and provide eastbound truck climbing lanes over Pacheco Pass.

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

This project proposes to construct a new 4-lane highway between U.S. 101 and SR 156 and provide 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 the economic vitality of the region.

Background

In January 2010, VTA and SBCOG executed a Memorandum of Understanding (MOU) to study the feasibility of a public-private partnership for the SR 152 Trade Corridor from US 101 to SR 99, and authorize the formation of the SR 152 Mobility Partnership to provide policy oversight/direction to the Project.

In 2015, VTA in coordination with the Council of San Benito County Governments (SBCOG) began the investigation of several new alignment alternatives for SR 152 between US 101 and SR 156. The Mobility Partnership consists of three elected officials appointed by the SBCOG and three elected officials appointed by the VTA Board. VTA provides the staff for the Mobility Partnership in consultation with SBCOG staff.

Objectives

  • Improve mobility between the Bay Area, Salinas Valley, and Central Valley
  • Improve reliability of travel times
  • Reduce traffic congestion
  • Enhance travel safety
  • Support economic vitality of southern Santa Clara and northern San Benito counties

Outcomes

  • Complete new highway as a continuous 4-lane facility between U.S. 101 and SR 156
  • Remove regional traffic from Gilroy and local roads
  • Provide eastbound truck climbing lanes over Pacheco Pass

Benefits

  • A new four-lane freeway between SR 156 and U.S. 101, to current design standards, and access control improvements will improve the safety and reliability of travel time between U.S. 101 and I-5.
  • The eastbound Pacheco Pass climbing lanes will improve travel times and safety by separating slower moving vehicles from traffic moving at freeway speeds.
  • Separate regional traffic from local traffic by eliminating 114 direct driveway access points to SR 152.
  • Increased mobility with a new connection to Santa Teresa Boulevard.
  • Increased access to Northern San Benito County
  • Reduced Green House Gas emissions and cut-through traffic.
  • Improve Central Valley access to future High-Speed Rail station

Project Status

Given the magnitude of the proposed Project and the potential for federal funding, the Project will be separated into phases.

US 101/SR 25 Interchange-Phase 1  

  • This project sets the stage for future implementation of the overall interchange reconfiguration slightly north of the current interchange. Phase 1 will accommodate future improvements to US 101, SR 25, SR 152, and provide a connection point at the interchange for a future Santa Teresa Boulevard extension to Castro Valley Road.
