The original Mallow Bridge was constructed in 1615 from timber. It and its replacements were swept away by floods in 1628, 1689 and 1712. A stone bridge was constructed in 1712 comprising of 15 equal arches. This too was badly damaged by a flood in 1853. The stone bridge was reconstructed in 1856. The reconstruction retained 4 of the original stone arches on the northern end of the bridge and the remainder of the bridge was replaced by 4 large segmental arches built using large blocks of dressed limestone. The use of segmental arches was a technological advancement at the time, enabling the spans to be wider and higher than previously possible. This increased the hydraulic capacity of the bridge and made it less likely to be damaged by floods.
