|Route outline (key)|
The B757 is a largely urban road in Scotland's central belt. For historical reasons it is out-of-zone, being entirely north of the A8.
It starts at a roundabout on the A806 just to the north of J3 of the M80 and heads north past Lenzie golf course to go through Auchinloch. A mini-roundabout is then reached where the B819 comes in from the left. The B757 is the dominant number in a short multiplex north to the next mini-roundabout where the B819 heads off to the east.
The B757 now runs north through Millersneuk to go under the Glasgow to Stirling railway line, then bends round to follow the line a short distance to the front of Lenzie station. The road continues north through town along Kirkintilloch Road before bearing eastwards to reach a roundabout back on the A806, which has bypassed the town.
There is then a short multiplex north along the remainder of the A806, bypassing Kirkintilloch town centre and crossing the Forth and Clyde Canal en route. At the top end is a signalised T-junction where the B757, still multiplexing, turns right onto the A803. It crosses the Luggie Water and turns left at traffic lights to regain its number.
The B757 heads north and soon reaches open country, which is largely flat. Much of the next section is through a wood, until the road becomes urban once more as it enters Milton of Campsie. The road heads north through town along Birdston Road, to end at a T-junction on the A891.
Originally the B757 started on the A721 on the edge of Uddingston. It headed north, passing to the west of Coatbridge before going through Gartcosh and Muirhead to reach the current route of the B757 in Millersneuk. The remainder of the road is as now, except that the B757 originally went through the middle of Kirkintilloch.
The road survived unchanged until the 1960s. The southern half of the road (between the A721 in Uddingston and the A80 in Muirhead) was then upgraded to Class I status, becoming the A752, which it remains.
Eventually the northern section of the B757 was altered as well. The road through Kirkintilloch town centre had been declassified by the 1990s; the A8006 (present A806) had been built to allow traffic to bypass the town. In 1992 the B757 was rerouted from Millersneuk to reach the M80 at the new J3, with the old road to Muirhead becoming an extension of the B819.
The most recent alteration of the B757 took place in 2010 with the construction of the A806 Kirkintilloch Link Road. This bypassed Lenzie to reach the M80, taking over the southernmost section of the B757.
