§ LORD BRECONasked Her Majesty's Government:
What are their proposals for increasing from two lanes to three lanes that proportion of the M.4 Motorway from the Almondsbury Interchange to the western exit at Newport: how many lanes will be provided on the proposed extension of the M.4 Motorway from Newport to Carmarthen.
§ LORD ABERDAREThere are no plans at present for increasing from two to three lanes the section of the M.4 Motorway from the Almondsbury Interchange to the western exit at Newport. 1579WA But my right honourable friends the Secretaries of State for Wales and the Environment have the question of the limits of its present capacity and the future of traffic in the area very much in mind and will keep it under review. The other information asked for is as follows:
- Tredegar Park, Newport, to St. Mellons (East of Cardiff)—dual three lane.
- St. Mellons to Coryton (North of Cardiff)—dual two lane.
- Coryton to Margam—dual three lane.
- Margam to Balgan (including the existing Port Talbot By-pass)—dual two lane.
- Baglan to Peniel Green (Morriston)—not yet decided.
- Morriston By-pass (Construction almost complete)—dual two lane.
- Pontardulais By-pass (Morriston By-pass to Pont Abraham)—dual two lane.
There are no proposals for a further extension westwards of the M.4 Motorway. Trunk road schemes to bypass Cross Hands and Drefach are in course of preparation, and the feasibility of improving to dual carriageway standard the whole length of the trunk road between Pont Abraham and the commencement of the Carmarthen By-pass is also being examined.
