Leith Street has now been closed for around three weeks with a raft of diversions and traffic measures put in place.
The route is off limits to facilitate a crane lift as part of the massive St James' Quarter redevelopment which is currently ongoing.
No traffic will be able to pass between Princes Street and Calton Road until the closure is lifted on Friday 24 May.
Edinburgh Travel News also report that Calton Road will be closed at Leith Street but pedestrian access will be maintained. In addition, the Greenside car park will only be accessible from the north end of the street.
Lothian Buses say that services operating on Leith Street, including the nightbus, will be diverted using a number of routes.
