Safety Improvement Project

This project proposes to widen shoulders from just east of the Alameda Creek Bridge to Interstate 680.

The Department of Transportation is reviewing the public comments on the draft EIR for the Niles Canyon 2 Safety Improvement project, and so we have not reached any conclusions at this time. We are investigating ways to reduce the project visual impacts even further, especially visual impacts associated with the retaining walls. Once we complete our analysis, we plan to meet with the local municipalities and conduct public outreach meetings to keep everyone fully aware of the latest developments to the project.
