Demolition experts have been working round-the-clock to remove a bridge over the M4 in Berkshire.

Signed diversions have been in place since the motorway was closed at 8pm on Friday. It's due to re-open by 6am on Monday.

Parts of the M4 will be closed for up to 28 weekends this year- that's closures for more weekends than its open. It's as work on the biggest smart motorway in the country begins its most disruptive stage of work.
