Easter will be a massive weekend for road works along the NW motorway, with closures at two key points. The St Lukes/Great North Road intersection and the Te Atatu city-bound onramps will be closed from 8pm on Thursday 2 April to 5am on Tuesday 7 April 2015.
But the good news: in both cases, bikes and pedestrian access will be uninterrupted.
