This bridge was built in 1908 it hardly ever had to open for water traffic. During a 30 year period it only opened 6 times and one 16 year period in never opened at all. It had a gas engine to open the draw. It is abandoned in place in the open position.

Judging by the charring, not by choice, but out of necessity.

It looks like one of the approaches was removed between 2018 and 2020..

Revisited this bridge on 8/27/20. Love this old swing bridge. I created some drone video footage as well as some still images. Really had a neat time exploring this old piece of history.
