History
Opened 1929

The Marion Memorial Bridge is a decommissioned 4-span metal truss bridge which formerly carried U.S. Route 41 in Marion County, Tennessee. It was built in 1929. The main span is 369 feet, and the bridge has a total length of 1870 feet. The bridge is historic, and the Marion Memorial Bridge was listed on the National Register of Historic Places on October 25, 2007. The bridge features an unusual truss configuration that is a hybrid of the Pratt and K-Truss configurations. This bridge crosses the Tennessee River and Nickajack Lake. The bridge was replaced by a new concrete and box girder span which opened in November 2014, slightly delayed from its original completion date of August 2013 by conditions encountered in the construction of the replacement bridge footings. Since the construction of the new bridge's footings would involve blasting within 30 feet of the Marion Memorial Bridge, state officials closed the bridge to vehicle and pedestrian traffic on January 9, 2012, with traffic being re-routed to the Interstate 24 bridge south of the span.

Some people in the community have expressed the opinion that they would like to see the bridge preserved in some way.[1] Tennessee Department of Transportation officials say the bridge is costly to maintain, citing as an example the repainting cost of $1 million.[2]

This bridge was built before Nickajack Dam, a few miles downriver. The higher mean pool of the new reservoir was reason for the bridge to be raised from its original height.

A bridge of similar design in Meigs County, Tennessee, that carried Tennessee Highway 58 across the Hiwassee River was imploded in November, 2007,[3] along with another similar bridge that carried Highway 58 over the Tennessee River in Roane County.
