|Route outline (key)|
The B5101 runs northwest from the Welsh border town of Wrexham.
It starts in Rhosddu, to the north of Wrexham town centre, on the B5425. It runs north, parallel to that road for a short distance whilst descending to go under the railway line at a low, narrow bridge. After climbing again, the road turns sharply left to head southwest and reach a roundabout, where it crosses the A541. This is the original southern end of the B5101. The road turns right at the next roundabout and goes under the A483 Wrexham bypass.
On the far side of the bypass the B5101 meets the B5433, which follows a similar course for the next few miles. Our road continues west through New Broughton into Southsea. There is a bridge under an unclassified road before the B5101 meets the B5430 then goes under the unclassified road again. Immediately afterwards is a link road joining this unclassified road (thus making this a very simple GSJ). It is signposted Wrexham and is certainly an easier way of getting there than the route already taken by the B5101.
A short distance further on is another overbridge, wide enough to be classed as a tunnel, where the road goes under a dismantled railway line. The road then climbs past reclaimed industrial land to reach the outskirts of Brymbo. It passes to the east of the village centre, meeting the B5433 again in the process. The original route of the B5101 was further west through the village centre, along a route largely destroyed by the steelworks, now also gone. Old and new routes join at the northern end of the High Street before the B5101 climbs to the north. It bends to the right, where it once crossed a railway line, before continuing on to meet the B5102.
Originally the B5101 ended here but since 1935 it has crossed the B5102 at a staggered crossroads to descend into the valley of the River Cegidog. The river itself is crossed in the village of Ffrith, after which the road follows the river upstream, also following Offa's Dyke and the dismantled railway line met to the north of Brymbo. After going through Llanfynydd the road climbs steeply out of the valley but still follows the dyke. We end a short distance further on at a T-junction on the A5104 on the edge of Treuddyn.
