The treacherous Rimutaka Hill Rd may get a $71 million upgrade over the next six years.
Greater Wellington Regional Council's transport committee prioritised the road sixth out of 17 transport projects it wants the Government to fund, in a draft plan tabled at a meeting on Tuesday.
NZTA has previously spent $16 million smoothing out Muldoon's Corner, the sharpest and tightest corner on the road, which it ranks as one of the country's most dangerous.
The committee, made up of all the region's mayors, has signalled it wants to improve the safety and alignment of the road.
Exactly what will be done to it is yet to be determined but Two Bobs Corner, the guardrail and Jims Corner have been previously identified for improvements.
