KILLIECRANKIE PASS, SCOTLAND.

An area of great science beauty, the narrow steep-sided valley of the Killiecrankie Pass in Scotland is invested with concrete viaducts and retaining walls of excellent workmanship. Simple but pleasing in appearance, the new A9 trunk road hugs the hillside while the structures are endowed with unity of concept, fineness of purpose, economy, ease of maintenance and durability - prime factors in their design and construction. Despite their grand scale the structures have blended admirably with the surrounding countryside, with the minimum of disruption to a region of historical and scenic importance. This article discusses the design concept of the road, and design and construction of the retaining walls and viaducts.
