While already notable as an early metal truss bridge still in active road service, this bridge has many properties that make it have an incredible amount of historic value. Built in 1889, this bridge employs Phoenix Columns, fabricated and patented by Phoenix Iron Works, for its upper chord and most of its compression members. The bridges configuration is a Baltimore Truss, which represents an early adoption of this type, especially for highway use.
Most of the design details are, however, common for its builder: Dean & Westbrook. During the later half of the 19th century this company fabricated bridges all over the east coast of the United States, and was the most prolific builder to employ standard use of Phoenix Columns in their construction.
As to be expected with its age, this bridge is pin connected and has a wooden deck. During the bridges rehabilitation in 2013 the historic nature of this bridge was exceptionally retained, with no modifications being made to the nature of the truss or deck support (e.g. no steel stringers being added)
Because of these facts the bridge has a posted weight limit of 3 tons, and according to locals this has been strongly enforced with local police doing weight checks.
