North south Greenway freeway walkway

The North-South Greenway Gap Closure Project is part of a regional effort to create a more extensive non-motorized transportation network in Marin County. It closes a key pedestrian and cyclist gap between the Central Marin Ferry Connector and the existing multi-use paths at the intersection of Old Redwood Highway and Wornum Drive.

The first phase of the North-South Greenway Gap Closure Project replaces the existing 4-foot-wide sidewalk along the US-101 northbound off-ramp with a 12-foot-wide multi-use pathway/bridge over Corte Madera Creek. This first phase, managed by Caltrans and built by Disney Construction, begins on the north side of Corte Madera Creek, at the touchdown of the Central Marin Ferry Connector (CMFC) Bridge and ends on Old Redwood Highway in Larkspur. Construction of the new multiuse path/bridge started in February 2021, the path was partially opened in March 2022 and will be complete in summer 2022.

The second phase, to be managed by the City of Larkspur, will continue the 12-foot-wide pathway along Old Redwood Highway to the Greenbrae Pedestrian Overcrossing on the east side of US-101. Construction of phase two is expected to begin in the spring of 2023.

Available Funding

The project is funded using Regional Measure 2 funding, which is a result of the 2004 voter-approved $1.00 toll increase of the seven state-owned toll bridges in the San Francisco Bay Area. The funds were redirected from the abandoned Greenbrae Interchange project.

Additional funds have been added to the project including, Transportation Fund for Clean Air (TFCA), Transportation Development Act (TDA) and Senate Bill 1 funds.
