Colwyn Road, Llandudno

The B5115 is a largely urban B-road on the Creuddyn Peninsula in North Wales.

It starts at J20 of the A55, where it also meets the A547. From here it heads north into Llandrillo-yn-Rhôs before descending to cross a couple of fields and enter the town of Penrhyn Bay.

There is a short split-level dual-carriageway section up Penrhyn Hill before the road passes to the south of the rocky Little Orme and descends again to run along Llandudno Bay, with the Great Orme clearly visible ahead.

Before getting to Llandudno town centre the B5115 reaches a roundabout. The road ahead is the A546 (which ends here) and the B5115 turns left along Clarence Crescent, a relatively new link road, to reach a roundabout on the A470. There is then a multiplex south along the dual-carriageway to the next roundabout where the A470 bears left. The B5115 regains its number by continuing ahead. It runs parallel to the A470 through Llanrhos before bearing westward into Tywyn. The road descends to the Conwy Estuary, where it ends at a T-junction on the A546, only separated from the water by a railway line.


The B5115 in 1956

The B5115 is listed in the 1922 Road Lists as Link at Llandudno. It started on the A546 on Llandudno Bay and headed south along Queen's Road to end on the A544 Conway Road.

In 1935 this section of the A544 was abolished. The new road into Llandudno from the south, the A496, took a different route and so the B5115 took over the old route of the A544 between Llandudno and Tywyn. The B5115 thus gained its current route through Llanrhos to Tywyn, as well as receiving a spur along Conway Road into the centre of Llandudno.

This situation lasted until comparatively recently and changed when the A546 and A470 were rerouted. Conway Road has become the A470 and so the main road into Llandudno from the south once more. Queen's Road is now unclassified as it has been bypassed by Clarence Crescent. However, the B5115 has gained the original route of the A546 east of Llandudno as far as the A55 on the edge of Colwyn Bay.
