Looking over the moors towards Rhydtalog
The B5104 was a long B-road in North Wales.
It started on the A494 at Clawdd Poncen, to the north of Corwen on the A5. The road then headed northeastwards along the valleys of the Rivers Morwynion and Alyn to Pen-y-stryt, where it crossed the A525.
The road then climbed into the hills, reaching a height of over 1100 feet, before reaching the River Alyn again (which takes a much longer route around the hills via Mold). After going through Penyffordd the road ended on the edge of Broughton on the A549.
The road was upgraded to Class I status in 1935. It kept its number so became the A5104. There have been a few reroutings since then (such as the Penyffordd bypass) but the current A5104 is essentially the same road.
