Another reason we need Transmission Gully

Ben Heather at Stuff reports:

A big quake could leave Wellington reliant on barges and helicopters for survival, new disaster predictions show.

Massive landslides would cut off Porirua, the Hutt Valley and Wellington from the rest of New Zealand and from one another, with inbound roads taking up to four months to clear.

All three areas would rely on barges and helicopters to ferry in food, clean water and vital medical supplies.

The would be no power, water or gas for at least three weeks, and for more than two months in some Wellington suburbs.

Wellington city would be cut off for the longest, with no power for at least two months and no gas for three.

It would take at least 55 days to open State Highway 2 between the Hutt Valley and Wellington, and three weeks to connect the capital and Porirua. …

Regional Emergency Management Group co-ordinator Bruce Pepperell said road access would be the biggest priority. “Parts of the region will be completely cut off from others.”

The stretch of State Highway 1 sandwiched between the coast and cliffs along Centennial Highway would probably be the most difficult to clear.

Another reason why is a very good idea. That if is the Greens don’t manage to kill it off, as they are seeking to do.
