Blane Bridge is the last bridge across the Blane Water before it meets the Endrick Water a little to the north. The bridge carries the B834 across, and due to the narrowness of the roadway priority signage gives priority to westbound traffic, although with the bend on the eastern bank and the slight hump over the bridge it can be difficult to spot oncoming traffic in either direction!
The Bridge itself is essentially a single span arch bridge, with the main arch deeply recessed between the abutments. However, on either bank there is a low dual purpose accommodation and flood arch, only really suitable for sheep to use, although this may be due to silting up on the bank since the bridge was built. There is a further, very low, flood arch on the western side, this time barely tall enough for a small dog!
Despite the bridges obvious age, it does not appear to be listed, and little of its date or history is currently known.
