Helmsdale Bridge

(Institute Civil Engineers Historic Engineering Works no. HEW 0258)

An unusual elevation Telford bridge of 1810–11 crossing the Helmsdale in twin segmental arch spans of 70 ft with a rise of 25 ft, its elevation being dictated by the width of the opening to be crossed. Its unresolved duality aspect is quite cleverly relieved by parapets which slope upwards from the abutments to form a flat inverted ‘V’ over the centre pier.

The bridge, which was built by George Burn for £2176, has stepped cutwaters carrying semi-hexagonal pillars which reach to the parapets. These, the string courses and tapered pilasters give the bridge a handsome appearance even though built in random rubble rather than squared masonry.
