Motorists warned of overnight slip road closure on Monday

The start of February has seen utility investigation and earthworks continue across the site. Traffic management will continue to be implemented on the roundabout as and when required to accommodate these various works during off-peak periods between 9am and 4pm. The M4 eastbound exit slip road will also remain reduced to one lane between approximately 9am and 4pm throughout February, subject to traffic volumes.

Lane closure

Motorists are reminded that on Monday 6th February, the westbound exit slip will be closed overnight. This is to install traffic management to allow works to start in that area. During this closure, traffic will be diverted via Junction 17.
