There is a full closure of the M4 this weekend in both directions between junctions 5 (Langley) and 6 (Slough/Windsor).
The closure will start Friday 27th September at approximately 8pm and this section of the motorway will be closed all weekend for the demolition of Recreation Ground bridge, a pedestrian/cycle bridge that links Datchet to Upton Court Park in Slough. The motorway will reopen on Monday 30th September by 6am.
The demolition work will begin overnight on the Friday and continue all weekend at all hours until it is complete. Motorway traffic will be diverted to the A4 and A355 through Slough for the duration of the closure. Recreation Ground bridge will be replaced in late Summer 2020 and re-open as soon as possible after then.
There is also a wider regional diversion plan that will advise drivers on the M25 heading west to use the M3 or M40 and then re-join the M4 further along – the westbound slip roads linking from the M25 junction 15 to the M4 junctions 4b will be closed over the weekend to help manage traffic. Similarly, drivers heading east on the M4 towards London will be advised to leave the M4 and redirect to the M3 and M40 to join the M25, or to reach destinations in Berkshire. Clear signs and signals will be in place on the network over the weekend.
There are two further closures between junctions 6 and 8/9 of the M4 in mid and late November to allow for the demolition and construction of bridges – with more to come in 2020 and 2021.
