Four-year $220m up­grade starts on SH16 cause­way

Auckland City Harbour News - - NEWS - By JAMES IRE­LAND

A $220 mil­lion project to lift the cause­way on State High­way 16 is un­der way.

The work is part of the western ring route project link­ing SH16, SH18 and SH20, pro­vid­ing an easy way to by­pass the city cen­tre be­tween Manukau and the North Shore while pass­ing through West Auck­land.

The cause­way project in­volves lift­ing a 4.5 kilo­me­tre sec­tion of SH16 by 1.5 me­tres to pre­vent flood­ing and to give more ac­cess to buses, pedes­tri­ans and cy­clists and adding ex­tra lanes. The work has a 2017 com­ple­tion date.

NZ Trans­port Agency state high­ways man­ager Tommy Parker says it will pro­vide eco­nomic ben­e­fits to North­land, Waikato and Bay of Plenty as the North Is­land pop­u­la­tion grows.

‘‘For the first time there will be di­rect mo­tor­way ac­cess be­tween the CBD and Auck­land In­ter­na­tional Air­port. The western ring route will also con­nect com­muters and freight with the rapidly grow­ing ar­eas in the north­west and the south­west of the city.’’

Be­tween the Great North Rd in­ter­change and the Te Atatu in­ter­change there will be four lanes in each di­rec­tion and bus shoul­der lanes.

Te Atatu MP Phil Twyford says he is de­ter­mined to get the fre­quent bus ser­vice run­ning all the way along SH16 into the city.

‘‘The ap­proach is not to build the busway all in one go, but to build it step by step. Each new ser­vice and piece of in­fra­struc­ture will at­tract in­creas­ing num­bers of pas­sen­gers, grow­ing de­mand, and jus­ti­fy­ing ad­di­tional in­vest­ment. This is pretty much how the North­ern Busway was built.’’

A lane for pedes­tri­ans and cy­clists will be built along the side of the mo­tor­way from Te Atatu Rd up to Hen­der­son Creek and along the Whau River bridge the lane will be 3m wide.

The T2 lane along the west­bound on-ramp at Great North Rd has been closed to traf­fic and will re­main that way for more than two years. The shared path for cy­clists and pedes­tri­ans will be di­verted on to the T2 lane.

The agency says most of the work will be done off-peak and all mo­tor­way lanes and cy­cle lanes will be kept open dur­ing peak hours.

Up­grade starts: Work to raise and widen the cause­way on SH16 be­gan last week.
