The Tyngsborough Bridge is a steel tied-arch bridge located in Tyngsborough, Massachusetts and carries Route 113 over the Merrimack River. With a span of 547 feet, it has the longest span of any steel rib through arch bridges in Massachusetts. It is also the 2nd oldest steel rib through arch bridge in the state.
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units.The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads.
A Howe truss is a truss bridge consisting of chords, verticals, and diagonals whose vertical members are in tension and whose diagonal members are in compression. The Howe truss was invented by William Howe in 1840, and was widely used as a bridge in the mid to late 1800s.

A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
