Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge includes a five panel through truss span and a single stringer approach span. Historic integrity of the superstructure appears to be good. As a late example of a pin-connected truss bridge, the structure is traditionally composed, reflecting the end result of three decades of movement from experimentation to standardization. Despite this standardization, bridges such as the 110th Street Bridge are becoming rare on today's roadways at a rapid rate. Further, compared to modern bridges built today, bridges such as this one offer a degree of detail and geometric composition that is beautiful and in stark contrast to the plain and ugly bridges that are built in the 21st Century. Today, the goal should be the preservation of all surviving pin-connected truss bridges regardless of any variances in local population from county to county and state to state. Wooden covered bridges have been treated in this manner, having been preserved across the board without regard to age, significance, or local population density, and as a result beautiful, historic metal truss bridges such as this one deserve no less.
