 The leatherworks in Pentrefelin and Tuttle Street, the many coal mines in the area, the brickworks in Abenbury, Brymbo Steelworks and the breweries all closed in the latter half of the 20th century.Wrexham suffered from the same problems as much of industrialised Britain and saw little investment in the 1970s.In the 1980s and 1990s, the Welsh Development Agency (WDA) funded a major dual carriageway (the A483) bypassing Wrexham town centre and connecting it with nearby Chester and with England's trunk road network.
