Truss Bridges
These are bridges in which the roadway or railroad is held up by a cage-like structure of dozens of smaller steel (or iron) members instead of a few heavy beams. This page contains links to a few truss bridges I have visited in North Carolina and elsewhere.
North Carolina

- Cape Fear Memorial Bridge -- A vertical lift bridge with a Warren truss main span, the longest bridge span in NC.
- Hilton Railroad Bridge -- Located in Wilmington, NC, this is a Warren truss bascule bridge that remains open most of the time.
- Surf City Swing Bridge -- Crossing over the Intracoastal Waterway, this was one of the few remaining truss swing bridges in North Carolina.
- Tar Heel Ferry Road Bridge -- an imposing Pennsylvania truss over the Cape Fear that was the longest fixed span in the state.
The Piedmont
- Cumnock Railroad Bridges -- Two Warren through truss bridges that have some interesting design characteristics.
- Deep River Camelback Truss Bridge -- Featuring an uncommon truss configuration, this bridge is now the centerpiece of a county park.
- Durham County Bridge No. 28 -- A rare multi-span Warren Pony truss bridge that was left standing when its replacement was built.
- NC 87 & 100 Railroad Overpass -- Built in 1938, this is a stout overpass built to cross a road at an angle.
- Norfolk Southern Cape Fear River Bridge -- A multi-span Warren truss railroad bridge that once carried the mainline of the original Norfolk Southern.
- Person County Bridge No. 35 -- A Pratt pony truss that has been bypassed and nearly become one with the forest.
- Rocky River Truss Bridge -- A pin-connected Pratt truss that still carries traffic on a quiet Chatham County back road.
- Sellars Mill Road Bridge -- A pair of relocated private pony truss bridges over the Haw River.
- Whitney Railroad Bridge -- A 1910 Warren truss bridge over the Yadkin which was original to the rail line.
The Mountains
- Barkers Creek Road Bridge -- An impressive nine-panel, 160-foot Camelback truss that has been bypassed but left in place
