Auckland mayoral candidate John Tamihere is proposing to turn the existing Harbour Bridge into a two-level superstructure - with 10 lanes for cars on the lower level and four rail tracks and walkways and cycleways on the upper level.
"A new 10-vehicle-lane harbour crossing, which will carry cars, rail, pedestrians and cyclists can be completed within six years on the existing bridge piers, replacing the existing bridge.There will be minimal disruption to traffic. My team have looked at overseas structures and costs and it is very doable.” Tamihere said.
Tamihere said full or partial superstructure replacements have been carried out on a number of bridges in the United States, including the Milton-Madison bridge, costing US$104 million ($161m), over the Ohio River. It was built in 1929.
"Either he intends to bankrupt the city, burden ratepayers with massive extra rates or he is making it up because he know he is never going to deliver it.Widening the motorway at either end to match the 18 lanes would see massive demolition of buildings and destruction of homes and neighbourhoods. This will cost further billions of dollars that Auckland doesn't have and the government won't pay for," Goff said.
