The A1 road around Gateshead and Newcastle upon Tyne after arriving from the south as the A1(M) from its origin in London, currently runs from the A1(M) terminus at Birtley. It then swings to the west of both Gateshead and Newcastle via Coal House, Lobley Hill, Metrocentre, Swalwell, Blaydon Bridge, West Denton, Fawdon and Wideopen to Seaton Burn interchange before continuing north towards Edinburgh. However, the A1 has followed a number of different routes in the Newcastle area, matching road developments aimed at reducing traffic congestion.
