Highways England are planning improvements to the M4 J15, along with the A419/A346 starting around December 2019/January 2020. These will be major works so long delays are to be expected.  This will also consist of the closure of DayHouse Lane whilst the bridge over the A419 is rebuilt and a proposed no right hand turn into Badbury from the A346.

We will publish more information as we receive it.

Letter from Highways England


Highways England operates, maintains and improves England’s motorways and major A roads. I am writing to let you know we will shortly be carrying out works in this area.

The works

As part of our commitment ot improve traffic flow in this area, we plan to improve capacity on the A419 by adding a dedicated left turn lane onto the M4 J15. To enable these works we need to carry out vegetation clearance ahead of bird nesting season. We anticipate these works will take 3 weeks to complete and will take place on the verge, no traffic management will be needed but there may be some noise. Please accept our apologies in advance for any inconvenience this may cause.
