Oldham: Yorkshire Street at St Mary's Way junction
The B6477 is what remains of the original route of the A62 through Oldham before the latter was diverted along Oldham Way. It consists of two disconnected sections in the town centre.
The western end of the road is at the A62/A627 (Manchester Street) roundabout, from where the road follows Manchester Street for one block to end on the town-centre route of the A627. The old A62 ahead has had the Magistrates' Court and the Town Square Shopping Centre built on top of it but it reappears as the pedestrianised High Street; all of this was numbered B6477 at one time.
The B6477 reappears at an apparently arbitrary point by the Town Hall and follows Yorkshire Street, which soon becomes one-way. By the Mumps Metrolink station, traffic is directed right over the tram lines onto Prince Street to end at traffic lights on the A62 Oldham Way; however the B6477 technically continues along a road called Mumps, which turns into a bus-only road in the other direction, which leads to the A62/A669 traffic lights. Prior to the construction of the Metrolink in the 2010s Mumps was two-way and open to all traffic, with the final junction a signalised Mumps Roundabout.
