Central Motorway Junction

A multilevel structure (three traffic levels crossing in several locations), it has been described as a "fiendishly complicated, multi-layered puzzle of concrete, steel and asphalt".During the duration of this NZ$208m project, the existing motorways had to be closed several hundred times during overnight, with traffic rerouted over local roads.The NZ Transport Agency was in November 2009 investigating a plan to extend the off-road Northwestern Cycleway through the intersection, to join it to Symonds Street and achieve better cycle linkages from the west into the Auckland CBD.[5] In mid 2010, it became public that a preliminary alignment had been chosen, with the cycle path using the Upper Queen Street bridge to cross the motorway.[6] A disused offramp was repurposed in 2016 as a dedicated walking and cycling shared path, extending the Northwestern cycleway through to Nelson street.
