M4 Junction 16 improvement works Set To Start

Road work to transform Junction 16 of the M4 will be starting soon. The works have been contracted to ensure the major highway interchange can cope with future traffic levels and, in particular, the nearby Wichelstowe development which will be using Hay Lane as a key artery route on to the M4.  

The construction costs are expected to be approximately £10 million and will see the following improvements:

  • widened slip roads
  • replacement of traffic lights
  • a dedicated right turn from the Wootom Bassett entrance on J16 to Hay Lane
  • improvements to the entries and exits onto the junction
  • a new footway from the Wootom Bassett entrance to J16 to Hay Lane

The motorway junction redesign is a requirement of the planning permission for the Wichelstowe development and needs to be complete before the 1,100th property on the site is occupied.

The junction will be open to traffic at all times, but there is likely to be some disruption to motorists.

Motorists will have noticed that vegetation clearance has already started on the approach to the junction and the project is anticipated to be complete by Spring 2018.

Labour Group Shadow Lead for Highways, Cllr Jim Robbins, said:
“The Labour Group certainly welcomes these junction improvements as J16 will be getting a lot busier once the Wichelstowe development is fully rolled out.

I hope the work on this junction can be done in a much more timely way than the Bruce Street Bridges junction took.”
