History of the road number
The original (1923) route of the A48 was the main east-west link in south Wales. The A48 in Cardiff was re-numbered to the A4161 on 19 November 1971 when the Eastern Avenue dual carriageway became the A48. By 2 November 1975, Queen Street was partly pedestrianised and 2 subways were opened under North Road and Boulevard de Nantes to allow the A4161 then to move from Queen Street to Dumfries Place, Stuttgart Strasse, Boulevard De Nantes. The A48 section between Rumney and St Mellons later became the B4487 and Southern Way was built in 1978.
