A smaller, narrower example was installed next to the railroad bridge for road traffic, which was removed sometime after World War I.

Their durability and ease of assembly greatly facilitated expansion of American railroads in this period.

Bollman's Wills Creek Bridge has also survived, but it employs a different type of truss system.

The bridge was surveyed for restoration in 1978 by Modjeski and Masters, which noted deterioration of the floor trusses.

[12] The bridge was restored by Wallace, Montgomery & Associates, LLP, for the Howard County Department of Recreation and Parks in 1983.

The Bollman truss suspends the deck from a network of tension members, while the top chord resists compressive forces.

The cast iron end towers, which transfer the weight of the structure to the abutments and pier, are also detailed.

A decorative and protective metal enclosure at the top of the towers was lost to vandalism but was replaced during the restoration work.

[13] The bridge was originally painted in a three-color scheme, documented in black-and-white photography, with specific shades unknown.
