HS2 will be undertaking works on a gas main (as part of the wider project) passing under the A40 between Gypsy Corner (North Acton) and Hanger Lane.
Woks will commence on Monday 21 August and continue until mid-November 2023 and will result in a contraflow of one of the eastbound lanes and an overall reduction of the road to two lanes in each direction.
