When route planning, remember that Edinburgh is a roadblock, despite the A720 ring road, at most times of day - unless that's where you're going, it's best to cut across from the A1 to the M6 using the A66 and then up the M74.Hi DD from home to Edinburgh roughly 250 miles . we can only do three weeks at a time no longer so a Route that would be worth seeing and then i will come back again 👍
When going to Edinburgh itself from the east, we use the A696/A68 from Newcastle rather than the A1.
