The Rte 774 Bridge is being demolished (April 2009). For the last 106 years it has been a 7 Panel through truss, NOT 8 panel. The Bridge is a Pin-connected, 7-panel Pratt through truss of 142.1 feet built in 1903 by the Brackett Bridge Company of Cincinnati, OH. The picture above is not the Rte 774 Bridge but the Rte 775 Bridge further down river.
This bridge is currently impassable, with VDOT closure signs blocking access. It is not readily apparent what the issue might be. That said, there is evidence that traffic of some sort has been circumventing the barricades - possibly farm equipment or 4-wheelers?
