Traffic has been banned from travelling along Edinburgh's Princes Street.
Cars and lorries have been banned from travelling along Princes Street
The city council first imposed a ban on eastbound vehicles back in 1996 and has now extended that idea to halt the westbound flow as of Sunday.
However, the restriction will only last from 0700 to 2000 BST each day with cars and lorries allowed back onto the road outside those hours.
The council believes the move will improve the city centre and be safer for workers, residents and shoppers.
Councillors also say it will significantly improve local bus services to the capital's famous shopping strip, which runs below and alongside Edinburgh Castle.
The plans form the second stage of the authority's Central Edinburgh Traffic Management (CETM) scheme, the first phase of which saw the initial eastbound ban.
The other implications of the scheme include pedestrians and cyclists being given priority on George Street with a series of roads in the New Town area blocked off to through traffic.
The council claims a third of Edinburgh's vehicles are merely passing through and not contributing to the economy and therefore need to be re-routed.
