The A702 is a major road in Scotland, that runs from Edinburgh to St. John's Town of Dalry in Dumfries and Galloway.

[1] As of 2013[update] it is not possible to drive this 0.3-mile (0.48 km) section continuously due to opposing one-way systems.

It continues in a south-westerly direction beside the Pentland Hills to Biggar, before following the Clyde Valley.

From Abington, it continues as a non-primary route, and overlaps the A76 road for 11⁄2 miles until Thornhill.

From Thornhill, the road winds south-west still, through the village of Moniaive, until eventually reaching St. John's Town of Dalry.
