Cal Park Hill Tunnel Rehabilitation and Multi-Use Pathway

The following project is sponsored by the Transportation Authority of Marin and funded in part by Regional Measure 2, a $1.00 increase in tolls on Bay Area bridges that was approved by voters in 2004 to fund congestion relief projects within the bridge toll corridors.

The Cal Park Hill Tunnel Rehabilitation and Multi-Use Pathway will provide a safe and efficient non-motorized alternative path of travel between two major transit facilities in Marin County, the Larkspur Ferry Terminal and the Bettini Transit Center in San Rafael. See Project Area Map   (2.8MB) The proposed route, which will be built primarily within the existing railroad right-of-way, would reduce travel time between these important public transportation facilities while eliminating traffic conflicts allowing for easy travel on an accessible path that is open to commuters, recreational cyclists and pedestrians of all ability levels. The project will include provisions to accommodate the shared use of the right-of-way with future commuter passenger rail service.

The County of Marin in partnership with the Sonoma Marin Area Rail Transit District (SMART) continues to make excellent progress during the construction phase.   The first phase consisting of re-opening the collapsed tunnel is now complete.  Construction of second phase is schedule to be complete later this fall.  We look forward to the opening of the Cal Park Hill Pathway.
