It is also significant for its use of both wrought iron and cast iron materials. The bridge is eligible for the National Register of Historic Places under Criterion C for Engineering as a rare survivor of a once-common Texas bridge type with unusual patented features and for its use of both wrought and cast iron. The bridge is also eligible for the National Register under Criterion A for its significance to local transportation routes and patterns.
