Why would the County of Marin want to restore Alto Tunnel?
The County of Marin owns the property on either side of the tunnel, and the railroad right-of-way has always been slated for use as a transportation corridor. Since the 1970s, the County has had plans for a North-South Greenway which would run along the Northwestern Pacific Railroad right-of-way, spanning Marin County from North to South, providing access to transit centers, businesses, schools, and town centers. There is currently a well-used multi-use pathway that extends for three miles, from Sausalito and through Mill Valley, leading right up to the south portal of Alto Tunnel. Another pathway continues north from the north portal of Alto Tunnel, through Corte Madera and Larkspur, approaching the Larkspur trestle.
