The B719 is a short link road in northern Dumfriesshire.
It starts on the A701 (former B713) a couple of miles north of Moffat. To begin with the two roads run northwards parallel to each other, with the B719 climbing away before bearing off to the left. It then heads west through a wood before zigzagging to turn northerly.
The road then descends a more-or-less straight road, known as the Greenhillstairs. The A74(M) soon becomes visible to the left, albeit some distance below, but as the B719 continues it gets closer to the level of the motorway.
Soon the road reaches a TOTSO. The original route of the B719 was straight ahead to end on the A74. When the road was upgraded to motorway status this was done online and so the original northern end of the B719 was declassified as there was no need for a motorway junction here, although the road does actually connect to the motorway as "works access" (the corresponding access to/from the northbound carriageway is slightly further north off the B7076). Now, however, the B719 TOTSOs left to go over the motorway and a stream before ending on the B7076 local access road.
