|Route outline (key)|
The B4546 is a short B-road along the left bank of the River Teifi. It was originally unclassified but gained its number in the mid-1930s.
The road starts at the Poppit Sands car park, where the other roads are unclassified, and heads inland along the river through St Dogmaels to the southern end of Cardigan town bridge. Here it turns right and follows the old route out of town of the A487 for around 500 m before terminating at a roundabout junction with the A478 and the present A487 at the southern end of the Cardigan bypass.
