2027 Transportation Improvement Program Projects - Line

Linear features from the full set of projects that are part of the Metropolitan Transportation Commission's 2027 Transportation Improvement Program (TIP). The TIP lists the near-term transportation projects, programs, and investment priorities of the San Francisco Bay Region’s surface transportation system that have a federal interest — meaning projects or programs for which federal funds or actions by federal agencies are anticipated — along with locally and state-funded projects that are regionally significant. A regionally significant project, generally large scale, changes travel patterns over a relatively large geographic area. The TIP signifies the start of the implementation of the programs and policies approved in the region's long-range transportation plan. It does this by identifying specific projects over a four-year time-frame that will help move the region toward its transportation vision. Locally funded transit operations, roadway maintenance projects, planning efforts and minor sidewalk or intersection improvements are generally not included in the TIP.
