Information about planned maintenance work to ensure the safety and resilience of the state highway network in the Bay of Plenty (BOP) region.

Maintaining your roads

More than $12.2 million will be spent on maintenance across approximately 210 lane km of state highway in the Bay of Plenty in the 2020/2021 maintenance season to help ensure the safety and resilience of the state highway network.

Some of the region's significant work sites this season will include State Highway 5 Dansey to Dalbeth Roads (Ngongotahā) and State Highway 2 east of Wharere Road (Pongakawa), as well as various safety works continuing along SH2 between Waihī and Ōmokoroa, and on State Highway 33 between Paengaroa and Rotorua.

The Bay of Plenty was one of the first regions to begin its spring/summer maintenance programme this year, due in part to the large volume of work scheduled.

While we aim to do this work with as little disruption as possible, there will be delays to journeys. We encourage motorists to plan ahead using the journey planner to minimise delays.

Road renewals

Road renewal involves ripping up the road and rebuilding it. These jobs usually take several weeks to complete and often impact journey times.

In addition to our resurfacing and renewal programmes, we also undertake an extensive programme of routine maintenance works including sealing cracks at specific sites and undertaking pavement repairs that need to be completed ahead of resealing in 2021 and 2022. 

Questions and answers

What is the resealing process?

Firstly, a thin layer of bitumen is spread onto the existing road. Then a layer of sealing chip is applied onto the bitumen. The sealing chips are rolled into the bitumen to provide initial bond. The road is then re-opened to traffic. Loose chips are swept up. Further sealing chip compaction occurs with managing the traffic over the site.

Why is maintenance work done during summer?

Warmer spring and summer months are the best time for resurfacing as daylight hours are longer and the warm temperatures and dry air help the new seal stick to the road surface. Warm weather helps ensure the new seal becomes strong and long lasting.

Bitumen is a liquid when it is hot and hard when cold. It can crack in cold weather, and wet road conditions will affect the bond between the bitumen and the road, leading to chip seal failures.

During peak summer it is a balance to programme as much work as we can before school returns while the roads are quieter, while also having the minimal effect on people’s holidays.

Why is there traffic management when nobody is working on site?

Even when there is no one on site working, we may leave temporary speed limits, signs and cones in place to protect road users. We need to consider reduced visibility, temporary surfaces, weather and changes to the road layout that people may not be used to.

When motorists disregard the traffic management, they put their safety, that of other road users and our road workers at risk.

Why isn’t maintenance work done at night?

Where possible, we work at night to minimise disruption to drivers on key routes. However, night work is more high risk for road workers. We are restricted by various factors, such as noise restrictions which are intended to ensure residents adjacent to works are treated considerately too.

When we do complete night works, the site still needs to operate under a reduced temporary speed limit for a period of 24-48 hours after the sealing before it’s swept. This allows vehicles to travel over the seal and help to bed in the chip. Following this, the site is swept, excess chip is removed, and the temporary speed limit remains in place until line marking has been reinstated. This is normally within 48 hours of the site being sealed, weather dependent.
