Historical Remarks:
The current structure is the fifth bridge to stand on this site. The first was constructed in 1794 at a cost of $366.66. That bridge was demolished by a flood and replaced in 1806 at a cost of $1,000. The second and third bridges were also destroyed by floods but immediately replaced in 1820 and again in 1824. The fourth bridge was destroyed by fire in late 1830. Rebuilding efforts began in March 1831 when $1,400 was allotted to cover the construction of two stone abutments and piers along with the purchase of other materials. In March 1832, an additional $1,500 was allotted to complete the construction. It appears that the fifth bridge was completed by early 1832. When it was first built, the bridge had hewn arches. New overlapping arches were added when the bridge was raised over the railroad in 1920. At one time, there was a sign posted at the bridge which prohibited riding horses across the bridge at a trot. It was believed that the impact of trotting horses could cause the structure to fall apart. The Bath Bridge is listed on the National Register of Historic Places.
