The Dornoch Firth Bridge
The Dornoch Bridge was opened in August 1991 by HM Queen Elizabeth The Queen Mother.
The contract to design and build the Dornoch Firth Bridge was awarded to Christiani-Morrison Joint Venture and the total cost was estimated to be in the region of £11.25 million.
The design proposed by the contractor involved the use of the “cast-push” technique of deck construction which allowed the bridge deck to be built in factory conditions behind the south abutment (Edderton) and launched across the firth.

The deck is supported on 20 piers each consisting of a reinforced concrete portal founded on two No. 2.1m diameter piles cast in place on a founding stratum up to 25m below seabed level. [Above information courtesy of Christiani-Morrison]

Only a few bridges have been built in Britain using this technique and Dornoch will be by far the biggest and, at 890m, one of the longest in Europe. It will reduce the journey time from Caithness and Sutherland along the A9 by approximately 30 minutes and 35 kilometres (22 miles). [Above information courtesy of Christiani-Morrison]
