The Drygrange Old Bridge is a former road bridge near the Scottish town of Newstead in the Council Area Scottish Borders . The building, which is now only used by pedestrians, was included in the Scottish monument lists in 1971 in the highest monument category A.
history
The bridge was built between 1776 and 1780 based on a design by the Scottish engineer Alexander Stevens senior . The Drygrange Old Bridge led the A68 until the adjacent new road bridge opened . Today the bridge is closed to motorized traffic.
Near the Drygrange Old Bridge, three bridges cross the Tweed with its modern successor bridge and the Leaderfoot Viaduct . Based on the nearby Roman field camp Trimontium , the sequence of the three bridges is jokingly referred to as "Tripontium".
description
The Drygrange Old Bridge crosses the Tweed around 700 m east of Newstead. The masonry viaduct spans the river with four lined segment arches . One of the middle arches has a clear width of 31 m, which is considerable for the construction period . The flanking arches are only around 17 m wide. The icebreakers are made of roughly hewn stone. Upstream they are pointed while downstream they are rounded. This design follows a French model that Robert Mylne had already taken up a few years earlier for the Blackfriars Bridge in London . For Scotland it is to be regarded as innovative for that time. Stevens took up the construction a short time later when building the Teviot Bridge . The arched gussets are decorated with urn motifs. A tooth frieze runs below the parapet . Above, the icebreakers continue along the pillars and end as pedestrian bays in the parapet.
