All the remaining roadworks and traffic management on the A580 East Lancs Road for the Leigh Guided Busway will be removed after the morning rush hour on Wednesday 2 December, Urban Vision report.
New traffic signals at Old Clough Lane will also be switched on.
From Wednesday 2 December bus lanes running alongside the A580 will also come back into action.
In a statement on their website the authority said: “All lanes will be open and operating to capacity from approximately 2pm (on Wednesday 2nd December).
“Some localised off-peak traffic management may be required over the forthcoming week whilst final works are completed, however it is not anticipated that this will cause any delays.
“The traffic lights and signalised junctions will be closely monitored to ensure that the traffic signals are managing the traffic flows as well as possible.”
The controversial £60m Guided Busway project has caused months of rush-hour delays to drivers.
Transport for Greater Manchester says the scheme, which links Leigh and Manchester city centre, will reduce rush-hour delays, but has been heavily criticised for the ongoing works delays throughout the project.
Works are thought to be nine to ten months behind schedule after “uncharted utilities” underground caused setbacks.
4.5 miles of guided busway between Leigh and Ellenbrook are now expected to be completed by spring 2016.
