Here is a little something different that I shot really quick yesterday while traveling down the river. The quality could be better since the boat I was riding on was going about 30mph.
Here is the former Georgia & Florida Railroad bridge, built by the American Bridge Company in 1908-09 at a cost of slightly under $140,000.
Alongside the south river bank is the drawbridge section. Of a type known as a Scherzer rolling lift, the 102-foot lift span rolls back from the river in a motion somewhat similar to that of a rocking chair. As it rolls, a huge counterweight moves down while the truss and railbed move up. In the photo below, the counterweight can be seen at the top left. Directly under it are the two "rockers," called segmental girders, on which the span rolls. When the bridge is closed, trains pass beneath the counterweight and between the segmental girders.
