Golden Gate National Recreation Area, Calif. (March 24, 2010)—Starting April 1, Conzelman Road between McCullough and Field Roads will close to all traffic including bicycles and pedestrians for six months. These additional closures are part of the Project Headlands safety and access improvements for several popular Marin Headlands roads.

Ricardo Suarez, the Division Engineer for the Federal Highway Administration said April 1 marks the end of the rainy season and the beginning of major construction operations for Project Headlands. The closure of upper Conzelman Road, including Hawk Hill, is the primary project impact to visitors in 2010. We ask for your patience while you experience delays. The project team is working to complete construction as fast as possible so that visitors can start enjoying the improvements the project will provide.”


Motorists will experience one-way traffic with up to 30-minute delays on McCullough Road. Intermittent delays will also occur on Bunker Road, Field Road, and Lower Conzelman Road between Alexander Avenue and McCullough Road.

East Road, near Fort Baker, will continue to be closed to traffic throughout each week starting Monday at 7 AM and reopening Friday at 4PM through May. During the road closure, motorist can access Fort Baker via Bunker Road. Off-road parking along East Road will be prohibited in some locations.


McCullough Road will be closed to bicycles due to the unsafe gravel road surface. Bicycles traveling on Conzelman Road from the Trailhead parking lot will be required to turn around at McCullough Road and return the way they came.

East Road continues to be closed to bicycles due to the unsafe gravel road surface. Bicyclists are directed to use the alternate route to Sausalito. Detour signage will direct bicyclists traveling across the Golden Gate Bridge via the east sidewalk to use Alexander Avenue. Bicyclists crossing on the west sidewalk will access Alexander Avenue by using the bridge walkway under the Golden Gate Bridge from the Trailhead parking lot.


Beginning April 1, trails accessing Conzelman Road between McCullough Road and Lower Fisherman Parking area will be closed. There will be no pedestrian access to Hawk Hill. In addition, the Bay Trail (between Fort Baker and Alexander Avenue) and Drown Road Trail in the vicinity of Fort Baker will be closed Monday through Friday. Pedestrian access on all other roads will be limited during work days.

Visitors are encouraged to visit the project website at for detailed road and trail maps describing the closures and delays.

About Project Headlands

Project Headlands is managed by the Federal Highway Administration working closely with the National Park Service. Project Headlands is needed to improve access and safety for motorists, bicyclists, pedestrians and transit on 11 miles of historic roads and trails with new, sustainable features. "This roadwork will be a change for the better," Acting General Superintendent Frank Dean said. "The visitor experience will be enhanced, while allowing the National Park Service to better protect what makes this national park site such an extraordinary place."

Construction began in February, starting with the closure of East Road, and will continue through the summer with reconstruction of McCullough and Conzelman roads. Project Headlands involves temporary road closures and delays over an anticipated four-year period. Most of the work scheduled for 2010 will occur during the months of February through September.

All efforts will be made to minimize disruption to the public; however, traffic detours and delays should be expected during certain phases of the project. Notifications and detour signage will be provided in advance of activities.

Information on the construction schedule, maps, and regular project updates will be posted on the project website at, or you can follow the progress on Twitter.
