"Significance: The Lockport Company Canal Bridge is significant as an intact representative example of a tower-drive vertical lift bridge, a subtype within the vertical lift bridge subtype. The bridge’s variation is demonstrated in the location of a separate motor and drive mechanism on each tower. The motor and
drive mechanisms power the two sheaves on each tower." [HAER_data]
None of the 22 HAER photos are digitized. That is very unusual and frustrating. But they do have four diagrams.

I added the label "bridgeGirderSteel" because the lift span is made with girders instead of a truss.
I documented this LDOT standard lift bridge design because it shows us what the Leeville Bridge used to look like. A standardized design makes sense because Louisiana has a lot of movable bridges because of the Intracoastal Waterway.
