Abergele Road, Llanddulas
When the A55 Abergele bypass was opened in 1968, the stretch of what had formerly been the main road running east from Llanddulas as far as Abergele town centre was reclassified and became the B5443. Following opening of the A55 Colwyn Bay bypass in 1985, the B5443 was returned to Class I status, becoming a part of a much extended A547.
Starting at the western end of the bypass the B5443 headed east through Llanddulas before heading east along a narrow stretch of flat land between the hills and the Irish Sea (with the A55 and the railway line also squeezing in) before reaching Abergele. The road ended in the town centre on the A548.
