Auldgirth Bridge is a bridge over the River Nith just outside Auldgirth in Dumfries and Galloway, Scotland. Designed by David Henderson of Edinburgh in 1781, it was built by William Stewart, and completed in 1782; Thomas Carlyle's father worked on its construction. The bridge is made of red sandstone ashlar, with three segmental arched spans, and carried road traffic and pedestrians; refuges are built into the parapets, supported by pilasters on the piers, allowing pedestrians using the bridge to move out of the path of heavier traffic.Wikipedia
