Kessock Bridge

Kessock Bridge, also known as Drochaid Ceasaig, was built between 1976 and 1982. It is a cable-stayed dual carriageway road bridge that carries the A9 over the Beauly Firth, connecting Inverness-shire and Ross and Cromarty.

The bridge was designed and constructed for the Scottish Development Department by Dr. Hellmut Homberg for the super-structure, with Trafalgar House Engineering Services Ltd handling the sub-structure. Ove Arup & Partners and Crouch & Hogg served as joint engineering consultants, while the Cleveland Bridge and Engineering Company and Redpath Dorman Long Ltd were the joint contractors.

Kessock Bridge measures a total length of 1,056 metres, featuring a main navigation span of 240 metres. There are seven smaller spans to the south and five to the north, each ranging from 60 to 80 metres in length. The deck is made of steel and is supported by four steel towers, with groups of eight steel cables arranged in a twin 'harp' shape configuration. The supporting piers are constructed of concrete. To safeguard against seismic and geological movement from the Great Glen Fault, the bridge includes buffers at the north abutment near the fault line, each weighing approximately 2.5 tons.
