The Mertoun Bridge is a bridge across the River Tweed in Roxburghshire, downstream of St Boswells. It is the first bridge on the river encountered above Kelso.
History
The Act of Parliament that authorised the building of a bridge was passed in 1837, and it was designed by James Slight of Edinburgh.[1] Although the original design was for a bridge built entirely of stone, it was eventually built with stone piers and wooden arches, but with sufficiently strong piers and abutments to allow stone arches to be used in the future.[2]
A flood in September 1839 washed away all the wooden parts.[3] It was rebuilt between 1839 and 1841 by William Smith of Montrose, with the piers raised by two feet compared with the original design.[2]
The stone arches were added in 1887.[4]
The bridge is a Category B listed building.[5][6]
Design
The piers are built between 1 and 3 feet into the bedrock, which was achieved by using cofferdams, and the depth of the bottom of the piers is between 6 feet 3 inches and 11 feet 7 inches below the summer level of the river.[2] The piers are 18 feet high from the summer level of the river to the base of the arches, and 29 feet 6 inches long and 10 feet deep, with a straight profile.[2] The masonry used is ashlar, and the stone is a reddish sandstone quarried nearby.[7]
The bridge carries the B6404 public road across the River Tweed near St Boswells. At the western end of the bridge is a toll-house, built on the embankment leading to the bridge.[8] Nearby is the Mertoun House Bridge, a suspension footbridge dating from the mid-eighteenth century.[9]
The Tweed is an important fishing river, and the Mertoun Bridge is the middle of the Mertoun Upper beat.[10]
