HistoryEdit

The tunnel's construction in 1914 served several purposes. The rail link supplied goods and mass transit to the Panama Pacific International Exposition the following year,[1] and the US Army utilized the line for construction of the Port of Embarkation.[2] The tunnel operated as part of the State Belt Railroad until the route's suspension in 1993.

In 2012, the National Park Service released a final environmental impact report on providing extended service though the tunnel to the San Francisco Municipal Railway F Market & Wharves line.[3] The cost of refurbishment and extension of the rail line was estimated at $60 million in 2017.[4] The E Embarcadero line may also see extension through the tunnel.
