Alert! Alert!
With over 350 miles of trail in place throughout nine counties, stuff is bound to happen. The Bay Trail Project will make every effort to alert the public to trail segments that are closed or detoured for upgrade, repair, or hazardous conditions. But that’s a lot of trail — let us know if we missed something major!
The Bay Trail and Covid-19
The State of California has issued a shelter-in-place order to slow the spread of Covid-19. If you find the need to be outdoors for physical and mental well-being, State and local health officials are recommending that you walk, run, hike, and bike in your own neighborhood and local parks while practicing social distancing of at least 6 feet. If you find that you’re unable to maintain 6-feet of social distancing, find another location where the 6-foot distance can be maintained to protect your health and the health of your family and community.

Trail Closures at Bedwell Bayfront Park in Menlo Park through 2020
Don Edwards San Francisco Bay National Wildlife Refuge has launched a levee maintenance and habitat enhancement project at the Refuge’s Ravenswood Ponds, on lands directly south of the City of Menlo Park’s Bedwell Bayfront Park. Maintenance work will shore up and repair pond levees, and, as part of the South Bay Salt Pond Restoration Project, ponds will be enhanced to create and improve wildlife habitat and build a new public trail. Trucks will need to drive through the Park entrance and on part of a San Francisco Bay Trail/Park perimeter trail that loops around the edge of the Park to reach Refuge lands. To protect public safety, the impacted Park areas and trail segments will be closed when trucks are present. Click here to sign up for e-mail blasts about the project.
