Marin Headlands Tunnel & Traffic Updates

Marin Headlands: Tunnel and Scenic Overlook Parking/Pull-Outs

Tunnel re-opened June 3, 2017

Updated June 6, 2017

The major phases of the Baker-Barry Tunnel preservation project are complete. Crews have addressed fissures and cracks in the tunnel wall, pumped polyurethane into the gaps around the tunnel lining, and installed a new, more energy-efficient lighting system. The historic tunnel is now preserved to bring the next generation of park visitors to the Marin Headlands.

Parking and pull-outs are now open to vehicles on Conzelman Road east of the McCullogh traffic circle.

For a summary of the work to date and photos inside the project, read this recent article in the Marin IJ.

 
About the Tunnel Preservation Project: Safer Surfaces. Better Lighting.

This project repaired the tunnel's concrete structure. Repaired cracks and leaks resulted in a slippery film of sediment that created a safety hazard for vehicles and bicyclists.

A new tunnel LED light system will reduce energy use by an estimated 40% from what was the single largest energy user at Golden Gate National Recreation Area! The new lights also better illuminate the tunnel for vehicles and bicyclists.

We also replaced water and sewer lines mounted in the tunnel. The outdated water and sewer lines were subject to frequent breaks which resulted in tunnel closures.
