I-280 Corridor Study

map showing the 280 corridor and study area​​​Overview

The I-280 corridor study’s primary objective was to identify multi-modal improvement projects for Santa Clara County’s next iteration of its long range transportation plan, Valley Transportation Plan (VTP). It is envisioned that the study also serves as the multi-modal study for identified projects to qualify for Senate Bill 1 transportation funding. The study area extends from the US 101/I-680/I-280 interchange in San Jose to the Santa Clara/San Mateo county line as shown on the attached map.

Through a collaborative effort with local, state, and regional stakeholders, the study considered a multitude of factors in the evaluation of improvement projects.  The factors were: improved mobility, promotion of multiple modes of transportation, transportation system benefits, cost, environmental and socio-economic effects, and community input.

The study is currently scheduled to be presented to the VTA Board of Directors at its January 2018 meeting.
