ed structure was completed in 1923. The bridge's overall length is 1054.7 feet (321.47 m), with a central span of 400 feet (122 m). It was added to the National Register of Historic Places
in 1989 along with several other area bridges as part of a multiple-property submission.
The current bridge replaces one built in 1889 and its pilings and foundation can still be seen to the south of the current bridge. During planning of this original bridge there was consideration and debate concerning its possible interference with river navigation.
In the late 1990s, there was an easy way to climb the arches under the bridge and walk along a path that spanned the entire way across the river. Vagrants, graffiti artists, and locals would frequent this area at all times of the day.
