The A4232, which is also known either as the Peripheral Distributor Road (PDR) (Welsh: Ffordd Ddosbarthu Ymylol) or the Cardiff Link Road (Welsh: Ffordd Gyswllt Caerdydd),[2][3][4] is a distributor road in Cardiff, the capital of Wales.
The first section of the PDR to be completed was the Southern Way Link Road in 1978 and the latest section was phase 1 of the Eastern Bay Link Road, known as Ewart Parkinson Road in 2017. When fully completed, the road will form part of the Cardiff ring road system.[5] The PDR runs west, south and east of Cardiff, with the M4 between junction 30 and junction 33 completing the northern section. The PDR is dual carriageway for its entire length except for Rover Way and the East Moors Viaduct, which is a single carriageway. The entire length of the road has clearway restrictions on it.
The PDR has been constructed in separate link roads of between 1.2 km (0.75 mi) and 5.47 km (3.40 mi) around Cardiff and to date 17.4 miles (28.0 km) including spurs have been opened to traffic, with plans for a further 5.53 km (3.44 mi).[6] It has 5 large viaducts (Ely Viaduct, Grangetown Viaduct, Taff Viaduct, Eastern Bay Link Viaduct and the East Moors Viaduct), 1 tunnel (Queen's Gate Tunnel) and 2 spur roads (Cogan Spur and Central Link Road). The road has many grade separated interchanges.
The section of the road between Junction 33 of the M4 and A48 at Culverhouse Cross is designated a trunk road in Wales and it's managed and maintained by the South Wales Trunk Road Agent. The remainder of the road is the responsibility of Cardiff Council.
