The single biggest roading project Porirua City Council has been involved with is expected to be officially locked in tomorrow.
The Wellington Regional Transport Committee will meet to include Transmission Gully in its programme of work for 2012-15, along with two roads linking the $1.3 billion highway to Porirua.
The new roads, through Waitangirua and Whitby, are expected to handle about 3400 vehicles a day.
The Waitangirua link road will connect Warspite Ave to an interchange at James Cook Drive, while the Whitby link road will connect Endeavour Drive to an interchange just south of Paremata Haywards Rd.
Porirua Mayor Nick Leggett said the fast-tracking of both projects was welcome progress. "We want this in the pipe before there's any future political instability around willingness or funding.
"I was up at Summerset retirement village in Aotea the other day and they asked me, ‘Will Transmission Gully ever be built?' and it was great to be able to say, ‘Yes, in all of our lifetimes'."
Construction of the link roads had to be brought forward to keep pace with the highway, which was originally pencilled in to be built beyond the 2014-15 financial year.
But the Government's decision to have a private sector consortium pay for and build Transmission Gully means the first sod will now be turned next year.
To speed up construction of the link roads, the council brought forward $2.2 million of spending in its Annual Plan this year. It has budgeted a total of $35m for the project.
The link roads were the largest single project Porirua City Council had been involved with and it would be making them a priority.
"Transmission Gully could bypass Porirua without them . . . we're taking this very seriously. This will be one of our major projects for the next three years."
A Transport Agency spokesman said tolling was still being investigated for Transmission Gully.
Will reduce travel times between Wellington and Whitby by 3 minutes and between Paraparaumu and Waitangirua by 7 to 15 minutes (depending on direction and time of day). By 2026, the number of vehicles on the Whitby and Waitangirua link roads is expected to be 3300 and 3400 cars a day respectively.
Without the link roads, James Cook Drive is predicted to see a 25 per cent increase in traffic by 2026, Discovery Drive will experience an 11 per cent increase and SH58 heading west will see 42 per cent more traffic. Daily traffic on the existing SH1 would increase by 5 per cent
