The A4232, which is known either as the Peripheral Distributor Road (PDR) (Welsh: Ffordd Ddosbarthu Ymylol) or the Cardiff Link Road (Welsh: Ffordd Gyswllt Caerdydd), 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 between Newport Road (A4161 road) and the Eastern Avenue (A48 road) in 1978.rem When fully completed, the road will form part of the Cardiff ring-road system. 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 the East Moors Viaduct, which is a single carriageway.
