SAUSALITO, CA - On Friday, May 10, Golden Gate National Recreation Area (GGNRA) will implement phase two of a traffic pilot program to relieve congestion, improve safety and parking, and enhance the visitor experience on Marin Headlands roadways. This traffic plan will be in effect through mid-fall, including Memorial Day, Fourth of July, Labor Day, and Fleet Week.

Vehicle traffic through Bunker Road and the Baker-Barry Tunnel in the Marin Headlands will be one-way in the westbound direction on weekends and return to two-way traffic Monday through Friday. Conzelman Road will convert from two-way travel to one-way travel in the eastbound direction between McCullough Road and Alexander Avenue, with a portion of the remaining travel lane dedicated for visitor parking seven days a week.

Bicyclists will not be subject to these restrictions and may continue to ride in both directions.

Traffic is expected to be heavy throughout this area and visitors can expect delays entering and leaving the Marin Headlands during the summer months and holidays. During phase two of the traffic pilot, drivers will be able to use the Baker-Barry Tunnel in both directions on weekdays. The park will continue observation of traffic patterns and initiate signage improvements in stages over the course of the summer and fall.

Phase one was completed last year in partnership with Golden Gate Bridge, Highway and Transportation District and the Presidio Trust to conduct research and determine long-term solutions to alleviate congestion.

Please use caution, follow traffic signs, and plan ahead prior to your visit.
