​​​​All Businesses and Park Attractions, including East Beach, to Remain Open

Starting the week of December 11, a section of Mason Street along the Presidio’s Crissy Marsh just east of Halleck Street will close for approximately six months. The closure will allow for the creation of seven acres of new marshland along the national park’s northern waterfront at a site to be known as Quartermaster Reach.

All park destinations and business at Crissy Field will remain open during the closure with detours in place.

Accessing East Beach:

  • Vehicles, bicycles, and pedestrians can continue to enter the Presidio at the Marina (Mason Street) Gate to access East Beach.

Accessing the west end of Crissy Field:

  • Bicyclists and pedestrians can continue to use the Marina (Mason Street) Gate and will use detours immediately around closure at Crissy Field.
  • Vehicles and bicyclists can follow the detour up Girard Road, turning right on Lincoln Blvd, right on Halleck Street and left on Mason Street or use McDowell Avenue.
  • PresidiGo Shuttle riders can still access west Crissy Field on the shuttle. The Crissy Field Route will be re-routed up Halleck Street; shuttle stops at the Crissy Field Center, Girard Road, the Presidio Community YMCA will be closed. A temporary shuttle stop will be added on Halleck Street at Mason Street.

This closure will allow for the installation of culverts beneath Mason Street that will allow fresh water to flow from the Presidio’s Tennessee Hollow watershed to meet the salt water of San Francisco Bay, creating valuable new habitat. The project will bring an 850-foot length of long-buried stream back to the surface and dramatically transform an area long covered by asphalt. When construction is complete in 2020, visitors will enjoy an up-close experience of nature along a new elevated bridge that winds through the marshland. It’s the latest step in a two-decade effort to restore the Presidio’s largest watershed.

Please allow a few extra minutes of travel to reach your destination at Crissy Field.
