Meadow Bridge (Shelburne, New Hampshire)
The bridge's total length was about 504 feet (154 m), and it was just over 18 feet (5.5 m) wide. Its three central spans were identical Pratt trusses, 133'4" long and 20' tall. The pony truss connected the main span to the southwestern shore, and measured 73'10". It was inclined at a 3% grade. The northern approach was a steel span with stringers 24' long over a 21'3" span. This approach was inclined at a 2% grade.
When the bridge was built, the river normally meandered in a channel that could be as wide as 400 feet. Silting and gravel deposits over time have altered the river's course, and it now is rarely wider than 250 feet. The main course of the river has been shifted northward, and the northernmost pier had been shored up to prevent it from being undermined. The bridge was one of the longest bridges of its type built in the state.
The bridge was listed on the National Register of Historic Places in 2003.
