Gillian Archer, from RoadSafe Northland, said the proposals were great news from a road safety perspective, and would also boost the region's economy.
"It's part of a 30-year plan, but it's going to be great for Northland and road safety. Bypassing the Brynderwyns will save time and reduce the dangers of having to travel over that winding stretch of road. It will save lives,'' Ms Archer said.
She said it was important to note the route over the Brynderwyns would remain open for those wanting to take the scenic route.
"But basically anything that improves safety, and these plans certainly will provide huge road safety benefits, has got to be great for the region."
John Bain, chairman of the Northland Regional Transport Committee - made up of representatives from Northland's councils and NZTA - said the plans would be a boon for Northland.
"It will make that road much safer and will mean a lot for the likes of the trucking industry.''
Three public information days will be held this month to explain the shortlisted options, answer questions and give people an opportunity to provide their thoughts on the plans: at Kaiwaka Memorial Hall, from 3pm to 7pm today, Mata Hall, from 3pm to 7pm on Thursday and the i-Site at Whangarei Town Basin from 10am to 2pm on Saturday.
