What is the Motorway Archive? Work on developing the UK Motorway system, which transformed British travel, started in the mid-1950s. The Motorway Archive celebrates the engineering achievement involved in the conception, planning, design and construction of this transport network by thousands of dedicated professionals. The Archive itself is a collection of as many of the documents and artefacts, which were associated with the development, as it has been possible to find. From this wealth of material has come the story of each motorway developed in Britain over the last 50 years. This is the story of the development of parts of the important Trunk Road, A1.

A1 Improvement schemes. Catterick North and South Junctions

Although coming in the new era of consultancy further "in-house" design was undertaken by North Yorkshire County Council for schemes to provide grade separation and eliminate the roundabouts at each end of the original Catterick By-pass, together with alterations to the side roads. A comparatively new and innovative design of the bridge at Catterick South was introduced, using pre-stressed beams with post-tensioned crossheads.
