The Catoctin Creek Bridge in Loudoun County, one of the longest surviving late-19th-century metal truss bridges in Virginia, was listed at the statewide level of significance in the National Register of Historic Places in 1974.  Research has confirmed that the 150-foot-long, single span, Pratt truss construction bridge was originally built around 1889, after a flood removed an earlier covered bridge. Due to increased traffic on Route 54 (the pre-1934 number for what is now Route 7), close calls on the one-lane bridge, and steep grades leading down to it, the state replaced it with a two-span, steel Warren pony truss bridge in 1932. The one-lane bridge was then dismantled and moved to its current site near Waterford in northern Loudoun County, carrying Featherbed Lane/Route 673 across Catoctin Creek. The Catoctin Creek Bridge, now renamed in honor of local preservationist John G. Lewis, was rehabilitated in the early 2020s.

An updated nomination for the Catoctin Creek Bridge/John G. Lewis Memorial Bridge was approved by the National Register in 2024.
