Bridge of Keir is a simple stone arch spanning the Keir Burn, which runs round the western side of Braco Village. The bridge carries the B8033, which while generally a narrow two-way road, is squeezed to almost single track to cross the bridge, which combined with the bends on either bank, forces traffic to slow as it crosses. The bridge is clearly an old structure, but unlike the Ardoch Bridge a little to the east, there is very little information on its history, and the structure itself gives nothing away either. The only thing which is out of the ordinary for a bridge potentially built in the late 18th or early 19th century is the shallow arch, where most are of a shape which is nearly semi-circular, the Bridge of Keir is a shallower segmental arch. This perhaps suggests a date later in the 19th Century.
