Highways England, Swindon Borough Council, Swindon and Wiltshire Local Enterprise Partnership and developers Persimmon and Redrow have joined forces to deliver extra lanes at M4 Junction 15 and improve local road access from the motorway.
The £17.5 million, 12-month project is due to start next month and will improve journey times and reliability for motorists by tackling congestion at both the busy M4 junction and on the A419, particularly at peak times.
The upgrade follows the start of two major Swindon Borough Council schemes – the Wichelstowe underpass project further south near M4 junction 16, and improvement work at the White Hart junction, a vital link between the A419 and A420.
The M4 junction 15 programme of work will involve:
- Widening of the A419 southbound approach to M4 J15 Commonhead Roundabout from 2 to 3 lanes, with a dedicated left lane for London-bound traffic;
- Widening of the A419 northbound exit from M4 J15 to 3 lanes up to the Highways England compound entrance, and back to 2 lanes north of the compound exit;
- Widening of the A346 to the south of M4 Junction 15 from 1 to 2 lanes; and from 2 to 3 lanes on the immediate approach to the roundabout;
- Widening of the M4 J15 eastbound exit slip road from 2 to 3 lanes;
- Lengthening of the 3-lane M4 J15 westbound exit slip road;
- Widening of the M4 J15 southern circulatory carriageway from 2 to 4 lanes;
- Upgrading existing footpaths and installing a new signalised pedestrian crossing over the M4 Junction 15 westbound entry slip road.
Highways England’s Growth and Housing Fund has helped to support economic growth, facilitate employment opportunities and enable housing development across the country, and £5 million is being invested in the junction upgrade, which is being jointly funded by Swindon Borough Council (£4.8m), SWLEP (£3m) and Persimmon and Redrow (£4.35m).
Mark Fox, South West Head of Scheme Delivery for Highways England, said: “Our roads are vital for the country and its economic success – they connect businesses and communities and support employment and new homes. All of our improvements will ultimately ensure our roads continue to improve journeys and unlock the potential for new jobs and homes.”
Swindon Borough Council’s £4.8m investment will complement more than £72.5m in road improvements at the nearby New Eastern Villages development.
Councillor Gary Sumner, Swindon Borough Council’s Cabinet Member for Strategic Infrastructure, Transport and Planning, said: “Anyone who has sat in the tailbacks at Junction 15 of the M4 at peak periods knows just why these improvements are needed.
“I am pleased this vital work is about to start as it will relieve congestion on what is a notoriously busy bottleneck. This is a further of example of the Council investing in the Borough’s road network to benefit both local residents and the wider Swindon economy.”
Paddy Bradley, CEO of the Swindon and Wiltshire Local Enterprise Partnership, said: “The scheme represents our continued commitment to local businesses and residents and the works will help ensure the economic growth of Swindon and the wider region is not hindered by traffic congestion and unreliable journey times.
“The collaboration between partners to bring together the necessary funding will lead to the improvement of major routes around Swindon to keep pace with the future development of the New Eastern Villages.”
Highways England’s Growth and Housing Fund has been used to match-fund infrastructure projects to unlock developments around the country. HE has approved contributions to 28 projects at a total cost of £94.8 million. This investment has in turn attracted up to £129 million in other public contributions and £102 million in private match funding and is anticipated to deliver up to 1.74 million square metres of commercial floor space, 44,000 homes and 45,000 jobs over the lifetime of the developments.
