The Walden Low Bridge is the downstream of the two bridges over the Wallkill River in Walden, New York, USA. It gets its name from being lower to the river than the Walden High Bridge a short distance upstream (replaced in 2005 by the new Walden Veterans' Memorial Bridge). It is a steel continuous truss bridge built in 1987, the latest in a series of bridges at that location that have been in place for at least a century.
