The new wire rope barrier will mimic the one installed by Sheepworld.
NZ Transport Agency has started installing another 2.2kms of flexible wire rope barrier along the Dome Valley to prevent head-on crashes.
The flexible wire will run through the road centre line south of Wayby Valley Road, from 70m south of the
Hoteo River Bridge to 100m north of Waitaraire Bridge.
Installation began on Thursday, March 4, and was expected to continue for two weeks.
The Dome Valley improvements are part of a government safety strategy, which aims to reduce deaths and serious injuries on New Zealand roads by 40 per cent over the next 10 years.
When a vehicle hits a wire rope barrier the high-tension wire cables flex, slowing down the vehicle and redirecting it back into the middle of the road to prevent collisions with roadside hazards or oncoming vehicles.
It is claimed that the flexibility in the wire rope means the barrier absorbs energy, reducing the force on drivers and passengers, resulting in less severe injuries than other barrier systems.
