Ferry Road Bridge
signs says one lane, but it could be two in a pinch

SUMMARY The 3-panel Pratt pin-connected half-hip pony truss bridge is supported on random ashlar abutments with wing walls. The abutments have
been reinforced with concrete toe walls. Washers separate the eye bars in the lower pin connections. Alterations include welded plates at
the panel points, additional diagonals, and outriggers. The original design has been compromised and render the bridge a technologically
undistinguished example of a well-represented bridge type in the county.
