M4 Junction 16 improvement works

Latest news and updates on the project

The multi-million pound upgrade of Junction 16 is now fully operational. All of the traffic management has been removed and the right hand turn towards Wroughton is now open. The traffic lights will be monitored over the next few weeks as the new intelligent MOVA system, which reacts to traffic, has been installed and some additional landscaping will be carried out. Please be aware that there may be some instances over the next few weeks of lanes being coned off for a short period to resolve any problems that may occur.

As part of a completely unrelated scheme to the work at Junction 16, Highways England will be working on the Eastbound entry slip at Junction 16, from Monday, 21 May until early July. This is part of a wider programme to improve the eastbound corridor of the M4. The work will be carried out overnight between 8.00pm and 6.00am and during this time they expect to have three full closures of the eastbound entry slip road.

Junction 16 improvement works

Swindon Borough Council have recently undertaken major works to remodel Junction 16 of the M4. The scheme was part of our plan to improve roads across the network and further enhance the growth and economy of Swindon and Wiltshire.

The scheme was funded by the Swindon and Wiltshire Local Enterprise Partnership (LEP) and the Wichelstowe Joint Venture. It was delivered by Swindon Borough Council in partnership with Highways England and Wiltshire Council.

The works ensured the major highway interchange can cope with forecast future traffic levels and cater for future development in the surrounding areas.

Hochtief (UK) Construction Ltd carried out the work, which is now complete.
