The A1 through Yorkshire forms part of a strategic link in the national network between Scotland, the Northeast and the South of England. Upgrading is already underway with the A1 Darrington to Dishforth design, build, finance and operate (DBFO) project. This includes the operation and maintenance of 33 miles of the A1 (M)/A1 (T) between Darrington, on the A1 just to the south of the existing A1/M62 interchange, and the existing A1/A168 interchange at Dishforth, east of Ripon, together with the design and construction of two Targeted Programme of Improvement (TPI) schemes which will provide 15 miles of dual, three-lane motorway.
