A1(M) Dishforth - Leeming

Scheme outline

Upgrade of the existing two-lane all purpose dual carriageway A1 to three-lane motorway standard, from Dishforth (the northern terminus of the North Yorkshire motorway) to Leeming Bar, approximately half-way to the next motorway section at Barton.

The original intention, to upgrade the whole section from Dishforth to Barton in one scheme, was replaced with two separate schemes to be completed one after the other. The Leeming to Barton scheme was then dropped due to government spending cuts.

This scheme was completed in and we're no longer accepting updates or changes to this page.
