Park improvement projects and weather-related events sometimes result in temporary closures and detours of trails around the parks. 

Fort Mason McDowell Avenue and Bay Trail Wall Repair Project

Starting in December 2015, the National Park Service will begin repairs to the failed historic retaining wall along the McDowell Avenue section of the Bay Trail in Fort Mason. These repairs will improve public safety and resource projection. The project will be completed by early summer 2016.

A section of the trail will be narrowed by fences for the duration of the project to allow for access to construction equipment along the wall.

The trail will remain open for the majority of the construction period; however, for short periods of time, the trial will be closed and a detour will be offered using alternate paths through Fort Mason.
