Since Waikato District Council installed 2.6 km of side barrier in April 2023, there have been a total of five collisions into barriers on Piako Road (two) and Gordonton Road (three).
These five collisions mean the barriers have prevented five run off road crashes that could have caused a death or serious harm. This stretch of road has a history of run off road crashes, carrying over 7000 vehicles per day in a 100km/h environment.
