Hochtief has won the contract for the transformation of Junction 16 of the M4.
The company will start initial works including site surveys, office installation and clearance work in mid-October, with the main construction work starting a month later.
The junction is being redesigned to take into account increasing traffic levels and a new housing development. Swindon Borough Council said around 5,500 vehicles an hour currently use Junction 16 at morning and evening peak times and this is expected to increase by more than 50% in the next few years.
The contract includes the widening of slip roads, roundabout alterations, drainage improvements and new traffic signals.
The money for the scheme comes from Swindon and Wiltshire Local Enterprise Partnership (SWLEP) and the Wichelstowe development, a housing development with Barratt Developments for at least 3,000 new homes. It is being delivered by Swindon Borough Council in partnership with Highways England and Wiltshire Council.
“Now we have appointed Hochtief as the contractor, the work on the much needed improvements to Junction 16 can start in earnest,” said Swindon Borough Council’s cabinet member for sustainability and transport Dale Heenan.
“The council is committed to improving the road infrastructure across the borough to ensure there is increased capacity in place before major housing developments are built. This scheme is part of our five-year strategic highways improvement programme, which will benefit not just people in Swindon, but those living in Wiltshire and visitors to the town.
“Hochtief was awarded the contract following a rigorous tender process and has an excellent track record of delivering major highways projects across the country. The fact Junction 16 is on the doorstep of the company’s headquarters also adds some additional local interest to the project.”
Hochtief managing director Sally Cox added: “We are delighted to be working with Swindon Borough Council, Highways England and Wiltshire Council to deliver these important improvements which will have a positive impact on the local area.”
