4-span Baltimore (Pratt) truss bridges across the French Broad River

This crossing is a half-mile west and downriver of the concrete deck plate girder Bridge #4, and is necessary because of an unusual horseshoe bend in the river. These bridges are numbered by their crossings of the French Broad River on the Norfolk Southern Railroad between Asheville, North Carolina and Knoxville, Tennessee.

Notice the tilted design, very typical of Baltimore (Pratt) truss bridges

This is one of two Baltimore (Pratt) Truss bridges in the area. The other is on the CSX Railroad, a 3-span crossing of the Clinch River at Starnes Slant, Virginia north of Kingsport.

Note the various steel alignments

The varied steel alignments make the Baltimore (Pratt) truss bridge one of the strongest built in this country of its time.

Leaning bridge?

From this angle, it looks like this span is leaning to the right. It is not. Baltimore (Pratt) Truss designs are aligned to how the bridge crosses the river, in this case, diagonal.

Believe it or not, this span built in 1927, replaced an earlier bridge built back in the late 1800's. The old river pier is still standing next to the one currently in use.
