From the A40 in St Clears, the A477 is a trunk road with primary status as far as Nash on the south-east side of Milford Haven. Responsibility for its management and maintenance lies with the South Wales Trunk Road Agency, on behalf of the Welsh Assembly Government. The road is downgraded from being a trunk road at the Waterloo roundabout in Pembroke Dock, and responsibility for maintaining the road from this point is held by Pembrokeshire County Council.


The 22-mile section of the road from its start at St Clears as far as Nash—which is a convenient distribution point for places on the south side of Milford Haven—was promoted to a trunk road following an announcement by the (then) Secretary of State for Wales, Cledwyn Hughes, on 14 November 1966.

The Kilgetty-Begelly bypass was completed in 1984 at a cost of £14.2 million. The Sageston-Redberth bypass was completed in 2002 at a cost of £6.4 million. A new bypass improvement scheme for the section of the A477 between St Clears and Red Roses was approved by the Welsh Government on 27 January 2012. Construction work on the new bypass began in mid 2012. Constructed with a straighter alignment and bypassing the villages of Red Roses and Llanddowror, the new section was scheduled to open during May 2014 but opened to general traffic at around 12:25 pm on 16 April 2014 having previously been declared open earlier in the day by Edwina Hart, Welsh Assembly Member for Transport.

  • St Clears
  • over the River Taf
  • Llanddowror
  • Red Roses
  • Llanteg
  • Kilgetty
  • Redberth

  • The A477 is 27.8 miles (44.7 km) in length.
