The B4487 in the northeastern suburbs of Cardiff is a road in two parts, separated from each other by a gap of some 1.3 km.
The first section of the road is a short "loop" off the A4161 Newport Road, running along Broadway in Roath (although it is the main road which in fact takes the slightly longer route). It appears that this is the original section of the B4487 and dates from at least 1935[1].
The second, and principal, part of the B4487 connects a signalized roundabout junction with the A4161 at the southwest corner of Rumney (the A4232 flies over this roundabout but does not connect to it) to another major roundabout in St Mellons, where it meets the A48. As its name, Newport Road, suggests, this section is part of the original route of the A48 running out of Cardiff towards Newport and became an extension of the B4487 when that road was rerouted in the 1970s.
