Skye Bridge - Design and Construction

Design and Construction

With the construction of road and rail connections to Kyle of Lochalsh toward the end of the 19th century, various parties proposed the construction of a bridge to the island. Although the engineering task was well within the capability of the age (the crossing is shorter and shallower than that bridged by the Forth Bridge), the island's remote location and its small population meant the cost of a bridge could not be justified.

Increased prosperity in the islands, and a healthy summertime tourist traffic, led to ever increasing volumes of traffic queueing for the ferries, and brought renewed calls for the construction of a road bridge. In 1989 Conservative junior minister James Douglas-Hamilton announced a bidding round, requested tenders to construct a toll bridge. A variety of locations and designs were proposed, and the contract was awarded to Miller-Dywidag, a consortium composed of Scottish construction company Miller Construction, German engineering company Dywidag International, and financial partner the Bank of America. The Miller-Dywidag proposal (designed in collaboration with civil engineering firm Arup) was for a single-span concrete arch, supported by two piers resting on caissons in the loch and using Eilean Bàn as a stepping-stone. The PFI plan was accepted, and received support from local MP Charles Kennedy and the local council in the full knowledge that it would be on a high-toll basis for a limited period. Although the bridge itself was built with PFI, the approach roads were the responsibility of the Scottish Office, which paid £15 million for the roads and associated improvements, and to cover the costs associated with decommissioning the ferry. Construction began in 1992 and the bridge was opened by Secretary of State for Scotland Michael Forsyth on 16 October 1995. At this time the ferry service across the sound ceased, leaving the bridge and the Mallaig — Armadale ferry as the only year-round connections to the mainland.
