THE M1 Motorway between Waterfall and Bulli Tops will be closed nightly for a week to allow for essential maintenance work.
The Roads and Maritime Service have advised of changed traffic conditions from Sunday June 16. An RMS spokesperson said the work will include trimming vegetation, clearing drains and litter collection, as well as repairs to the road surface, guardrail and signs, to improve safety for motorists.
The M1 Princes Motorway will be closed at the intersections of the Old Princes Highway at Waterfall and Bulli Tops while this work is carried out.
To improve safety and allow the work to be carried out as efficiently and effectively as possible, the closure will be in place between 8pm and 4am for five nights from Sunday 16 to Thursday June 20, weather permitting.
Motorists can detour via the Old Princes Highway.
Information about this and future road closures, including detour maps, is available at rms.work/srrc. Motorists are advised to plan their journey allow an additional 10 minutes travel time, drive to the conditions, and follow the directions of signs and traffic control.
