Here is some information that may answer some of your questions. The original bridge consisted of three 90 foot fixed deck truss, double-track spans and one deck truss draw span.The foundations of the old piers were used but the masonry was taken down and replaced with piers wide enough for four tracks. (This information is from the Nomination Form of 1977)
"This bridge was unique because it was originally powered by two diesel engines rather than electric motors. The engines, which had fluid torque-converter transmissions were located at track level inside the operator's house just east of the movable span. Power was transmitted from the operator's house to the movable spans by means of shafts and gears, with the final operating effect carried out by a pinion, mounted to the moving span, that engaged a fixed rack." (Connecticut DOT 2004) The gears and shafts in the photo are likely remnants of the old arrangement, left there from the 1990 rebuild when electric motors were installed.
I know this bridge was built in 1905... but it REPLACED another drawbridge and I cant find ANYTHING about the previous bridge. I know it existed because it is mentioned in harbor improvement reports from the 1890s. Also, some of the gears from the works of the previous bridge are still sitting there on the ground at the East end of the current bridge. Any ideas?
