The B5090 is a short link road in east Cheshire, connecting Bollington to the rest of the classified road network.
It starts on the A538 (former A523) on the northern edge of Tytherington, itself in the north of the Macclesfield urban area. The road heads northeastwards and soon reaches a roundabout on the current route of the A523. The B5090 was rerouted here when the A523 was built but its original route is still clearly visible, especially from the air, just to the east of the roundabout.
Our road now heads north through Bollington Cross, where it meets the B5091, before continuing vaguely eastwards into Bollington itself. It goes under the former railway line from Macclesfield to Marple, now the Middlewood Way footpath, and then the Macclesfield Canal, immediately after which it bends slightly left at a set of traffic lights.
The road continues along Palmerston Street, through the centre of town, before ending on a mini-roundabout. No other roads here are classified. The road ahead climbs to Pott Shrigley and ultimately returns to the A523 in Adlington.
