Six Alternative Routes to the Sunset District (1924)
Alternate routes that the N Judah might have taken instead of the Duboce Tunnel.
The report predicted that once the Sunset was fully built out, there would be five or six streetcar lines there, all routed through the tunnel. Predicted running time from 20th Avenue to Kearny: 26 minutes via Duboce, 31 minutes via the Mission-Sunset Tunnel. Actual schedule time today: 27 minutes, even with the Market Street Subway. The abandoned Eureka Station in the Twin Peaks Tunnel was built with the Mission-Sunset Tunnel in mind.
