The road will carry SH1 traffic while the Buckle Street underpass is constructed.
From this Friday, drivers will once again be able to get on and off Buckle Street from the top of Tory Street but will have to use the Basin roundabout and Rugby Street to get into Tasman Street.
If you are turning from the Basin roundabout on to the new Buckle Street diversion, watch for the new signalised pedestrian crossing at the intersection of Sussex and Buckle streets. The crossing is part of a new pedestrian and cycle route between Tasman and Tory streets.
Access to Massey University and the National War Memorial will be from the city-end of Tasman Street.
NZ Transport Agency Wellington State Highway Manager Rod James says the roading changes will be in place until the new underpass is completed in late 2014.
"Heavy machinery will be on site from mid- February and trenching starts in early March. We thank the public for their patience while they get used to this new road layout as we work towards the development of the Memorial Park underpass."
The Government announced in August that it planned to underground Buckle Street between Tory and Taranaki streets so a new memorial precinct could be developed above it.
