Part of M4 to be closed this weekend as £848m smart motorway upgrade work continues
Part of the M4 will be closed all weekend as work on an £848 million upgrade to add extra lanes and new technology continues.
The motorway will shut westbound between junctions 8/9 (Maidenhead) to 10 (Wokingham/Bracknell).
The closure is part of the four year smart motorway upgrade, which will see 32 miles of motorway converted, and is due to be completed in 2022.
As part of the M4 project, 11 bridges will be replaced to make room for a new lane where there is no existing hard shoulder.
Around 130,000 vehicles travel on the M4 each day, the motorway is the main strategic route between London, the West of England and Wales.
Highways England says the smart motorway changes will create more reliable journeys along the route between junctions 3 and 12.
More weekend closures will be in place later this month.
Diversions for drivers this weekend
The motorway will close westbound between junction 8/9 and junction 10 from Friday evening (July 10) until Monday morning (July 13).
The closure is expected to be in place from 9pm on Friday until 6am on Monday.
The diversion route for motorway traffic during this weekend is via the A404M, A4, A3290 and the A329M.
When will the project be completed?
Highways England says it is making “steady progress” between junctions 8 and 9 to junction 12, which started in July 2018.
It expects to finish most of the work on this section before the end of 2020, before opening it as a smart motorway during 2021.
