I'm guessing that is a pin-connected bridge.

CARTERSVILLE BRIDGE & GUARD GATE

CA. 1913

This view looking east was taken a short time after two major breaches occurred at the recently widened Great Embankment.  The guard gate was one of the design improvements resulting from reconstruction of the embankment carrying the canal across the Irondequoit Valley. The guard gate proved its value in 1974 when sewer constrction caused a breach occurred just east of Bushnell's Basin.

The bridge linking Marsh Road and East Street was removed in 1941 when the steel was scrapped for World War II.  Mitchell Road located a half mile to the west had originally been a private lane serving the Guernsey/Mitchell estate.  The road was dedivated as a tiwn road and became the permanent detour.  The old Auburn Line railroad embankment is visible on the right side of the photo.

See Guard Gate #4 and #12 for contemporary photos of guard gates.
