BRIDGE HISTORY
The New Hope-Lambertville bridge was originally completed on September 12, 1814. It was 32' wide and was a multiple arch bridge (6 arches, 175' long each, 13' high). This bridge was used until 1841, when it was damaged heavily in a flood. The second wooden bridge was also carried away by the flood of 1903. The present truss bridge was constructed in 1904.
