Document Description
The Marin County Public Works Department proposes to construct a pedestrian tunnel beneath Lucas Valley Road in the vicinity of Big Rock Ranch, Nicasio, Marin County, to provide a safe connection between two important segments of the county trail system. The site is located approximately 5 miles west of U.S. Highway 101. The proposed 76-foot long tunnel would connect the Big Rock Trail on the north side of Lucas Valley Road with Loma Alta Fire Road on the south. Both trails are part of the Bay Area Ridge Trail, a multi-use ridgeline trail route that circles the San Francisco Bay connecting parks and open space.
