National hopes motorists get the message

National Party leader Don Brash is certain his new roading billboard near Auckland's spaghetti junction will not distract passing motorists: they will be driving so slowly past it in traffic snarls they will have ample time to read it, he says.

The billboard, which went up on Friday, is a small part of the party's effort to make roading one of its key election points of difference with Labour.

Over the coming weeks he will spell out more details of how different a roading network would be under National.

This month he announced that National would devote all the petrol tax to roading, an extra $600 million a year.

Yesterday he said that that would not happen immediately after the election but gradually because it would take time to for the road construction industry to cope.
