United States Highway (US) 101/State Route (SR) 25/Santa Teresa Boulevard Extension Project

The Santa Clara Valley Transportation Authority is advancing the United States Highway 101/State Route 25/Santa Teresa Boulevard Extension Project in Gilroy, California, with the goal of reconfiguring the intersection of Santa Teresa Boulevard and Castro Valley Road and extending Santa Teresa Boulevard to directly connect with the US 101/SR 25 interchange. The project includes widening the new segment of Santa Teresa Boulevard from two to four lanes over a 0.9-mile stretch to align with improvements from the earlier US 101/SR 25 Interchange Improvement Project Phase 1. Additional elements involve constructing a barrier-separated Class I bike path, installing traffic control systems such as signals or a roundabout, building retaining walls up to 30 feet in height, relocating utilities and power lines, and integrating stormwater management features including bioswales and drainage infrastructure. Roadway lighting will be implemented, and all work will be confined within existing right-of-way limits to minimize land disturbance. Environmental compliance is a central component, with the project undergoing full review under the California Environmental Quality Act and the National Environmental Policy Act, evaluating impacts on air quality, biological resources, noise, water quality, greenhouse gas emissions, cultural resources, and community land use. The lead agency, VTA, is responsible for oversight and environmental documentation, while Caltrans serves as a lead agency under NEPA. The project’s place of performance is clearly identified as Gilroy, California, with all construction and inspection activities centered along the Santa Teresa Boulevard corridor and the US 101/SR 25 interchange. Public input is solicited through formal comment periods with a deadline of August 24, 2026, including in-person meetings and submission options via mail or email. The current documentation reflects a planning and environmental review stage, with no formal contract value, pricing structure, or federal acquisition regulation clauses identified, indicating the project is in a pre-procurement or forecasting phase. Contact for project-related inquiries is Alex Bode, Environmental Planner III, with supplementary support from Ian Kroll of Circlepoint. No contract administration data, payment details, invoicing systems, contracting officer representatives, or offeror certifications are present in the provided materials, underscoring that this is primarily an environmental planning document rather than a finalized procurement contract.
