Archaeological Works on the A1 Leeming to Barton Improvement Scheme

NAA are pleased to announce that we have been selected by the Carillion Morgan Sindall Joint Venure as archaeological contractor on the A1 Leeming to Barton Improvement Scheme. This phase covers the 24km section from Leeming Bar to Barton, following the route of Great North Road which is closely aligned to the Dere Street Roman road. The new road alignment follows the course of these earlier roads for parts of its length and continues on the existing route through the Roman town of Cataractonium to the south of the River Swale and an associated suburb to the north. The new A1(M) will, however, avoid the core of the Roman settlement at Bainesse.

The area has a long history and a number of excavations are planned along the length of the scheme. NAA will be investigating sites that have been identified through desktop studies, fieldwalking, geophysical survey and trial trenching. The earliest archaeological evidence to be encountered is located in the vicinity of Leeming Bar where early Mesolithic occupation has been identified. Further investigations are planned around Little Holtby, where substantial quantities of flints were recovered in the mid-1990s.

As part of this scheme, the existing Agricola Bridge over the River Swale, the cutting to the south and the embankment to the north will be widened to accommodate the enlarged carriageway and bridge-widening. Fort Bridge which carries the existing A6136 Catterick Road over the cutting will also be replaced. Immediately south of the river Swale, the excavations will investigate the northern Roman town defences and their relationship to Dere Street. On the north bank of the Swale, and to the east of the existing A1, the excavations will provide an unprecedented opportunity to examine the development of the Roman suburb.

Between 2009 and 2010, NAA worked with the Carillion Morgan Sindall Joint Venture on the A1(M) Dishforth to Leeming Improvements (click here ). We undertook a series of major excavations over the 21km long scheme, which uncovered a range of material dating back as far as the Neolithic period. We are proud to be selected to continue our work with the Carillion Morgan Sindall Joint Venture and the Highways Agency.
