The prime minister has announced that work on Transmission Gully will start next year, just before the elections.
Construction on Wellington’s controversial Transmission Gully road link will begin in the second half of next year – and open to traffic in 2020.
Prime Minister John Key confirmed the move at a keynote speech to Wellington’s Chamber of Commerce this afternoon.
It follows contentious comments he made earlier this year, claiming the city is “dying”.
Key confirmed work on the $2.5 billion “northern corridor” – from Levin to the city’s airport – will begin next year.
The preferred bidder would be announced early next year, probably February, Key said.
He emphasised the Capital’s importance as a transport hub.
“The recent earthquakes have boosted the already-strong case to upgrade routes into and out of the region so it can better cope with such events,” he added.
The upgrade will shave 40 minutes off the morning peak travel time from Levin to the Capital, he said. It will also cut road fatalities from 140 to 100 within five years of opening.
And he claims it will create “thousands of new construction jobs”.
However, the project has encountered opposition from locals.
The route also lies on a fault line.
Others say the money should be spent on upgrading a rail link.
A public-private partnership will maintain and operate the link for up to 25 years.
There are a lot of issues with Transmission Gully that I will try to go into in greater detail in a future post however the main problems are that:
- it performs poorly economically -primarily due to its massive cost at about $1 billion.
- it isn’t all that clear it would perform any better in an earthquake than the existing coastal road
- it will be built as a PPP which will save us the upfront cost but will lock us in to paying huge annual fees over a 25 year period that will see us paying about 3 times what it cost to build. The NZTA have even removed the risk for the winning companies as they will have to pay for the road even if no one uses.
- Due to some steep elevation changes it is unclear that trucks will even bother using the route, especially if it is tolled
The map below shows where the road is going
The image below shows the change in elevation over the route.
While the videos below give an idea of what it will look like. You can see there are going to be some absolutely massive cuts into the sides of hills along with some massive embankments just to build the route.
