"It's been amazing that - especially at the northern entrance - there hasn't been a major accident this year.
"On one particular day there were approximately 55 heavy vehicle movements plus packhouse workers' cars, shift workers and golf club members, in and out of Tapairu Rd alone," he said.
NZTA has announced it will create both left and right turning bays at the southern entrance to Tapairu Rd.
NZTA's regional transport systems manager Wayne Oldfield said that to enable traffic to continue to enter and exit both ends of Tapairu Rd, there would be gaps left in the flexible median barrier.
"Conversations with the community, along with our safety investigations, highlighted that the majority of people use the southern entrance to Tapairu Rd as visibility is better and the road is flatter.
"We found that a few simple changes to this intersection would make it even safer and encourage people to choose it over the northern one," Oldfield said.
As well as the new turning bays, the passing lane on the southward stretch of the highway between the two entrances to Tapairu Rd, would be removed and replaced with a wide shoulder, he said.
"This will make it safer for motorists who currently have to turn into and out of Tapairu Rd across the passing lanes."
Oldfield said some cost-effective improvements would also be made to the northern entrance of Tapairu Rd, for drivers who chose to continue to use it.
"The 50km/h speed signs in Waipawa township will be moved further south, slowing traffic travelling past the northern entrance to Tapairu Rd.
"This will make it safer and easier to turn on to and off the highway. We also plan to widen the road shoulder around the northern entrance to Tapairu Rd. This will create extra room for traffic to pass vehicles waiting to turn."
Measures welcomed
McCleary said extending the 50km/h limit would "certainly be a major improvement" for the northern entrance to Tapairu.
But he said NZTA should focus on reducing the left-hand bend on SH2 to improve sight-lines and reaction times for northbound traffic.
"With the huge increase of heavy vehicles now using this highway, NZTA could increase visibility for northbound traffic by shaving the batted bend on the left-hand roadside before the Tapairu northern entrance and Ongaonga Rd."
He also said signage should be erected to alert northbound traffic about the concealed northern entrance to Tapairu Rd and the approaching intersection with Ongaonga Rd.
"Personally, I've been in touch with [NZTA] for some temporary signage to warn motorists of turning trucks and vehicles. But it comes to back to who's going to pay for the signs."
A "decent slipway" into the northern entrance of Tapairu Rd would also be far safer for locals and heavy vehicles accessing the road, he said.
"Heavy vehicles exiting Ongaonga Rd to go into Tapairu Rd would be able to manoeuvre out of the southbound traffic way quicker, rather than trying to get up to speed travelling up the hill to the southern entrance," McCleary said.
The $20 million safety upgrade is being undertaken in four stages,starting from the north and heading south, with work between Waipawa and Waipukurau included in the last section of the project, which is scheduled to be completed by July next year.
