Cardiff / Caerdydd is the capital city of Wales, situated on the country's south-east coast.
By the mid 20th century traffic congestion in the city was increasing due to growing car ownership. New roads were planned to cater for the expected growth in traffic. One of the earlier proposals of the period was for an inner bypass to relieve the A48. The line for this was fixed in 1958 but it took over a decade before it opened in around 1970 as Eastern Avenue.
The mid 1960s saw the beginning of the most ambitious schemes.Hook Road due to its shape. The Hook Road was the responsibility of the City of Cardiff. At the same time another part of the network was being developed by central government. The Llantrisant Radial and Eastern Avenue were to be trunk roads which would provide an inner bypass for Cardiff until the M4 to the north of the city was built. Traffic levels at the time suggested the M4 would be needed until much later.
Things were progressing slowly, not least because of environmental concerns and loss of property. The 1968 map shows how many houses would be affected by the new roads. 3386 would be affected in total. These figures appear to exclude commercial property. In adddition the Hook Road was planned to cut a swathe through Cathays Cemetery where it joins the A48 which would require a vast number of graves to be exhumed. This together with vocal community opposition meant the alignment for the some of the roads and junctions were altered in places to reduce the impact on the community but the roads were still a source of friction.
Eastern Avenue was completed along with the three level junction at Gabalfa in around 1970.
In the summer of 1971 the government transferred responsibility for the Llantrisant Radial to the city and county councils. The city was already battling to get the Hook Road built so it came as no surprise when the Llantrisant Radial was scrapped soon afterwards to the joy of those who lived on either of its two planned routes. The government meanwhile brought forward plans to complete the M4 around Cardiff meaning the inner bypass would no longer be needed.
By late 1972 the Hook Road had also bitten the dust. Again, local residents were celebrating the road's demise. By now the grand vision of Buchanan was in tatters and the remainder of the proposed roads were also canned. The only roads that were built was Eastern Avenue and the short spur between Eastern Avenue and the Southern Primary.
While residents who lived on the routes of the scrapped schemes were celebrating the city council went back to the drawing board. The need for road improvements was still there and in the late 1970s a much reduced scheme was planned. This would be a loop around the south of Cardiff running between the spur off Eastern Avenue and the M4 at M4 J33 together with a short spur between the docks and city centre. This was built during the 1980s and 1990s as the A4232 except for the eastern section which remains unfinished. Part of this road closely follows the line of the earlier Buchanan era proposals between M4 J33 and Llandough. The section adjacent to the Ely River in particular matches the alignment of the Western Tangential.
