Plans to build a new twin-road toll tunnel beneath the River Thames in east London have been approved by the Department for Transport. The Silvertown Tunnel will link the Royal Docks north of the river with the Greenwich Peninsula in the south. Transport for London said the route will cut congestion and ease pressure on the Blackwall Tunnel, but opponents believe it will increase air pollution. The tunnel is expected to be operational from 2023. Mayor of London Sadiq Khan said the crossing "is vital for the future prosperity of east London."
