Two fire trucks, three water tankers from Whanganui and five rural crews were responding.
NZ Transport Agency Waka Kotahi advised road users to avoid the section of SH3.
Late Friday morning, NZTA said SH3, between Pukerimu Rd and Rangitatau East Rd, was closed because of a roadside hedge fire.
“Emergency services are on site, as windy conditions have blown the fire across the road. Fire crews are currently battling the blaze on both sides of the state highway.”
The road closure began at 11.30am. It reopened about 1.30pm under stop/go management.
“Road users are advised to avoid the area, delay their journey or use an alternative route.”
Dalton said the cause of the fire was not yet clear.
“Scrub fires are always difficult when they’re on hills because of access ... they’re always labour intensive.”
The scrub fire burning on both sides of the highway would cause visibility issues for drivers, he said.
