Bridge Documentation

This stone arch bridge is one of the only known bridges in the country to feature cast iron railings. The Historic Bridge Inventory claims that Henry E. Finch was the architect for the bridge, yet the railing has a casting that states that Robert P. Gallagher was the architect. James D. Field fabricated the iron railings for the bridge, while the bridge contractor was John. H. Silvers. The historic bridge contributes to the Mill Hill Historic District.

Information and Findings From New Jersey's Historic Bridge Inventory


The handsome 2-span rubble-coursed stone arch bridge with its original cast iron balustrade, the only known example of its type in the area, was designed by Trenton architect Henry E. Finch. He also did the 1869 S. Clinton St. stone arch bridge. The well-preserved bridge with voussoirs contributes to the architectural significance of the Mill Hill Historic District. The 1977 NR nomination does not include an inventory, but the bridge is mentioned in the text as a contributing resource. It is also individually significant based on its type, completeness, and association with architect Finch. The bridge is individually eligible for listing in the National Register under Criterion C and is a contributing element to the Mill Hill Historic District.


The bridge carries a city street over Assunpink Creek in an urban, mid-19th century mixed use neighborhood in downtown Trenton. The surroundings are dominated by row houses that are being restored. Some modern, incompatible redevelopment has occurred to the north and east of the bridge. The span contributes greatly to the historic character of area.

Bridge Considered Historic By Survey: Yes
