Route description

The PDR has 3 separate sections; the Capel Llanilltern Interchange (M4 J33) to Queen's Gate roundabout, the Rover Way – Lamby Way roundabout to the Llanedeyrn Interchange (A48) and the Pontprennau Interchange (A48) to the Pentwyn Interchange (M4 J30).

This section from the Capel Llanilltern Interchange on the M4 (junction 33) to the Queen's Gate roundabout is sometimes referred to as the Western Link Road , is 15.77 kilometres (9.8 mi) in length and includes the Capel Llanilltern – Culverhouse Cross Link Road, Ely Link Road, Grangetown Link Road and Butetown Link Road.

It is 4.83 km (3 mi) in length and was opened in 1982 and built by Davies Middleton & Davies Ltd (DMD). It was designed to relieve Ely of through traffic and partly cuts into Leckwith Hill.

 along with local residents objected to the scheme that they said would cut through Butetown and split the community, creating an unnecessary physical barrier between the two areas to the north and south of the link road. By 1988 South Glamorgan County Council had agreed to change the design of the link road, despite having already spent 6 years of design work on the link road meant that a tunnel had to be built instead. The cost of the Butetown Link Road was estimated to cost £35 million, but this had risen to £45M in 1988, before the design change.

The contract to build the Butetown Link Road was eventually won by a local company Davies Middleton & Davies Ltd in a joint venture with an Italian contractor, Cogefar-Impresit UK Ltd. The bid of £60 million undercut all other bids by £10 million, Davies Middleton & Davies Ltd have subsequently gone into administrative receivership.

The viaduct was constructed using precast concrete segments, which is widely used in the construction industry for medium to long span viaducts. Segments were made in a casting yard near the site and then transported for final assembly of the viaduct.

South Glamorgan County Council also commissioned a sculpture by Kevin Atherton for the foot and cycle path on a specially constructed viewing platform. The work was to mark the completion of the Taff Viaduct so that the sculpture should be visible for the benefit of pedestrians, cyclist and motorists alike.

Eastern Bay Link Road

It is envisaged that the 5.25 km (3.3 mi) Eastern Bay Link Road will run from the Queen's Gate Roundabout to the Rover Way – Lamby Way Roundabout on the Southern Way Link Road, although at present only the first phase between Queen's Gate Roundabout (51.468090°N 3.156193°W) and Ocean Way Interchange (51.472328°N 3.144107°W) is officially at the planning stage, although it seems to have now been mothballed.

The link road had previously been known as the East Moors Link Road – Phase 1 and 3, but it also included the East Moors Viaduct, which was originally known as the East Moors Link Road – Phase 2. Later it became known as the Cardiff Bay Link Road, then renamed the Eastern Bay Link Road.

The proposed Eastern Bay Link Road, along with other schemes have been subject to many planning proposals since the last link road (the Butetown Link Road) was finished in 1995, namely a local transport plan (Local Transport Plan 2000–2016) in August 2000, a green paper

However, the current proposal from Cardiff Council of 31 October 2006 is to complete the first phase of the road, approximately 1 km (0.621372736649807 mi) in length, from the Butetown Link Road to Ocean Way Interchange. The new route would be a different route from the earlier proposal and would avoid any encroachment into the nature conservation area, which Friends of the Earth and the RSPB had objected to. Therefore the new route of the link road should ensure that there are no objections.

Southern Way Link Road

The Southern Way Link Road , generally known simply as Southern Way, was built in two parts; the first section of Southern Way to be completed was between Newport Road (A4161 road

) in 1978. The final section of the link road was built between Newport Road and the Rover Way – Lamby Way roundabout and was opened in 1984 at a cost of £9 million and includes the East Moors Viaduct, which is also known as the Southern Way Flyover. In 1987 it was envisaged that the present single-carriage was would be "twinned" as a dual-carriageway, the same as the rest of the PDR. The 2.25 km (1.4 mi) link road now runs from the Rover Way – Lamby Way Roundabout (51.493127°N 3.133759°W) to the Llanedeyrn Interchange (51.507202°N 3.145853°W) on the A48.

) Project Award and also a Concrete Society Commendation, both in 1985 for work on the viaduct. The viaduct was constructed by concrete box girder deck of segmental construction. The East Moors Viaduct was originally known as the East Moors Link Road – Phase 2, but now forms part of the Southern Way Link Road.

Pentwyn Link Road

The Pentwyn Link Road , which is also known as the North Pentwyn Link Road, runs from the Pontprennau Interchange (51.528660°N 3.130240°W) on the A48 and the Pentwyn Interchange (51.541525°N 3.128749°W) on the M4 (junction 30). It is 1.61 km (1 mi) in length and was opened by John Redwood

Cogan Spur (A4055)

The Cogan Spur, which is also known as the Cogan Link , from the Ferry Road Interchange (51.453519°N 3.184876°W) to Barons Court Junction (51.447910°N 3.189787°W) on the A4160 was opened in 1988. It is only 0.8 km (0.497098189319845 mi), but it is an important link to provide access to the PDR from Penarth and the southern part of the Vale of Glamorgan. It also bypasses Penarth Road (A4160) for traffic going in and out of Cardiff city centre.

The most recent development, which began at the end of 2006 and into 2007 was the widening of the road between the Cogan Viaduct and the Ferry Road Interchange to a 3-lane dual-carriageway. A new junction was also built for the Cardiff International Sports Village

, each weighing from 43 to 117 tonnes. The Cogan Viaduct was again designed by South Glamorgan County Council, who won a Concrete Society Commendation in 1989 for the design.

Central Link Road (A4234)

The £8.5 million Central Link between the Queen's Gate Roundabout (51.468399°N 3.157366°W) and the junction on Adam Street (51.479557°N 3.167631°W) on the A4160 was opened on 16 February 1989. When it was first opened it only linked Cardiff city centre with Cardiff Bay. It was not until the Butetown Link was opened on 27 March 1995 that this road started to be used as a link to the motorway network, Penarth and the Vale of Glamorgan. It will not be until the Eastern Bay Link is built, when traffic from the city centre will use it to travel east, that it will be fully used. The length of the A4234 is just 1.45 km (0.90099046814222 mi) and is entirely a two lane dual carriageway with clearway restrictions.

Ely Spur

The Ely Spur was planned to run from a new interchange on the Ely Link Road to Ely Bridge on the A48. It was only 1.2 km (0.745647283979768 mi) in length, but it would have reduced through traffic in the residential area of Ely, namely on Cowbridge Road West

, from Cardiff to Cardiff Airport is also the main road from Barry to Cardiff and is the main commuter route.

One of the 4 proposed schemes involved a new major highway route linking the Ely Link Road (PDR), south of the Culverhouse Cross Interchange, through to the A4226 north of Barry. The estimated cost of this scheme would have been £96m, including the widening of the A4232.
