More Newell Rd blockage to come

Share

More disruption to traffic at the State Highway 1 – Newell Rd intersection is expected as reconstruction of the crumbling culvert under SH1 winds up.

More than $769,000 worth of repairs of the colourfully named Dreadnought Culvert began just over a week ago and is expected to finish, depending on weather, in about a week’s time.

A large amount of heavy machinery, including a crane, has been needed for the reconstruction, requiring Newell Rd to be closed off at the intersection with SH1 as it was moved in.

More partial blockage or full closure of the intersection is likely over three days when the machinery is removed, probably mid to late next week.

The culvert, about 50 metres north of the SH 1 – Newell Rd intersection, carries the Mangaonua Stream and much of its reconstruction has been largely out of sight below road level.

NZTA said the work, being done by contractors Brian Perry Civil, was preventative maintenance on a structure that had been in place for many years and had been found to be degraded.

The three quarters of a million dollar repair job would return the structure to “original purpose requirements,” NZTA said.

The work would “assist in ensuring that this section of State Highway 1 is not impeded unexpectedly in the future,” the agency said.
