|Route outline (key)|
The B4548 runs along the right bank of the River Teifi downstream from Cardigan. The road was originally unclassified but came into being in the mid-1930s.
The road's current southern end is at traffic lights at the end of the A487 Cardigan bypass. We follow the old route towards the town centre through an area of light industry and housing before a TOTSO right by the bowling club marks our road's original starting point. We now head north through the suburbs and presently reach open country.
We now bear left and descend towards the Teifi and run along the estuary as far as the bar, where we become separated from the river by a caravan park (the road itself remains straight, however). The road now narrows as it runs above the river mouth and passes a golf course on the landward side. The road quickly reaches Gwbert, with excellent views over the coast to the left, before ending at a sharp right-hand bend, with the continuation through the village unclassified.
