Haywards Hill has reopened after urgent repairs and safety improvements following a serious crash last week.
The State Highway 58 road was closed between the Hayward's Hill intersection and the Pauatahanui roundabout from 10am today, and reopened at 3pm as scheduled.
Last week it was the scene of a three-vehicle crash that resulted in the death of Upper Hutt man Richard van der Linden, 28.
NZ Transport Agency said the safety repairs were planned long before last week's fatal crash.
Spokesman Anthony Frith the work involved some resealing of the road, and some new signage and road markings.
"It's reopened and we just ask people to keep a few minutes up their sleeves because of the speed restrictions."
There will be a 30kmh speed limit on the highway on Thursday and Friday while the new surface on the road sets. This would cause delays of about 10 minutes.
After last week's fatal crash, NZTA pledged to look into safety concerns over the black spot stretch of the highway between Mt Cecil Rd and State Highway 2.
Between 2009 and last year two deaths and 14 serious injury crashes happened there.
''[We] will be carrying out an immediate and full investigation in conjunction with other road safety authorities to understand what caused the crash and what might be done to prevent similar tragedies,'' NZTA Wellington highways manager Rod James said.
It was exploring a lower speed limit and other options on which the public would be consulted later this year.
After a man died on State Highway 58 in October, Wellington district road policing manager Inspector Donna Laban called it ''the worst highway in the Wellington region''.
Mt Cecil resident Jo McCready said safety concerns on the road went back ''decades'' and were highlighted about 18 months ago when a tip was proposed for the road.
