|Route outline (key)|
The B6392 is a road in Midlothian running through Eskbank and continuing on as a bypass of Lasswade and Bonnyrigg.
Starting from the Gilmerton Road Roundabout junction with the A7 and A772, west of Dalkeith, the route runs south-east for just over a kilometre along Gilmerton and Melville Roads, crossing the River North Esk, to reach a six-way roundabout in the centre of the Eskbank area of the town, where it meets the A768, A6094, and B703.
Next heading south along Dalhousie Road, the B6392 meets the A7 again at Hardengreen Roundabout. Here the re-opened Borders Railway crosses over the junction by means of a 72-metre long precast concrete bridge constructed in 2013–14. We continue south-westward around the eastern and southern fringes of Bonnyrigg, on new-build named prosaically, but accurately enough, the Bonnyrigg Distributor, before the route comes to an end at a second meeting with the A6094 about a kilometre north-east of Rosewell.
The section through Eskbank follows the original line of the A7 and gained its number when the bypass was completed in the early 1990s. The remainder of the road, the Bonnyrigg bypass, was built in the late 2000s.
