Baker-Barry Tunnel Closure (Marin) - late 2016 - Spring 2017

September 19, 2016 Posted by: GGNRA Public Affairs

A Federal Highway Administration project to repair and improve the Baker-Barry Tunnel will impact traffic flow to the Marin Headlands. The tunnel will close for a preservation project, routing all headlands traffice on Conzelman Road.

For public safety, the parking area at Battery Spencer as well as the vehicle pull-out areas east of the McCollough Road traffic circle will be closed in order to maintain a safe flow of traffic.

Battery Spencer remains open to hikers and cyclists.

The project is scheduled to begin Jan 9, 2017 and last through early May 2017.

GGNRA has created a website to provide the latest information of the tunnel project, including alternative traffic patterns, detours, and more.
