The Ken Bridge is a road bridge about 0.8 kilometres (0.5 mi) north east of New Galloway in Dumfries and Galloway, Scotland, which carries the A712 road over the Water of Ken towards Balmaclellan.

[3] Rennie died on 4 October 1821, before the construction of the bridge was complete.

[5] It curves along its length, and has a total span of 110 metres (360 ft), with the widest central arch spanning approximately 30 metres (100 ft).

[5] Its piers are supported on the riverbed by round-nosed cutwaters, and the spandrels between the arches are decorated with pilasters.

Architectural historian John Gifford, writing in the Dumfries and Galloway volume of the Pevsner Architectural Guides series, described it as a "long elegant curve of granite ashlar",[1] and John R. Hume, the former chief inspector of historic buildings for Historic Scotland, wrote that it was the "most elegant of Rennie's bridges in the South-West... ...five graded segmental arches leap the Ken's floodplain in a long, low streamlined curve.
