Description:
The base of the Portland Heights cable-car trestle, where the powerhouse which ran the cable was also situated.
The trestle was 1,040 feet long and climbed at a 20.93% grade (roughly 20 feet vertical for every 100 feet horizontal).
The trestle was discontinued in 1904 with the completion of the Vista Bridge. I'm not sure when it was actually torn down, tho' I have to assume it didn't last long.
