The crowded roads in St Asaph have been a hot political issue for many years. In recent years, increasing volumes of traffic on the A525, St Asaph High Street, which links A55 with the Clwyd Valley, Denbigh and Ruthin, have led to severe congestion in the city. This congestion is having a detrimental effect on the city, and residents have repeatedly called for a bypass to take this north–south road and its traffic away from the city, but the National Assembly for Wales rejected these calls in 2004, presenting a further setback for residents campaigning on the issue.
