Movable bridges over the Royal Canal
See here for an excellent summary of the various movable bridges which have spanned the Royal Canal, Dublin.[8].
A skew lift bridge immediately south of the Newcomen Street road bridge carries a railway branch line over the canal. It was constructed by Somers Railway Engineering.
The Spencer Bridge or Sheriff Street Bridge carrying Sheriff Street over Spencer Dock was described as a swivel bridge when opened in 1873. It was designed by James Price, and a wooden buoy 10ft diameter and 10ft deep supported much of the weight of the movable span. Replaced in 1941 by a lifting bridge or drawbridge.
