Waikato and Bay of Plenty state highway works for April and May 2023


As colder nights become the norm, we are preparing to roll out the winter road maintenance programme. Given the weather-related delays we experienced at the start of 2023, some of our summer projects continue, along with final road resurfacing works across the Waikato & Bay of Plenty region.

Of note this week was the opening of the Bayfair Flyover on State Highway 2 in Tauranga. While work continues on this project, the ability to use the flyover is a milestone to be celebrated.  

Recovery work following Cyclone Gabrielle continues to progress, and teams are making head way in Coromandel and West Waikato, says Cara Lauder, Waikato System Manager at Waka Kotahi NZ Transport Agency. 

“We are close to completing the slip repairs on the SH23 road to Raglan, and progress on the SH31 road to Kāwhia site has been good. We’ve also been able to start work on key slip sites around SH25 on the Coromandel, while we await the confirmation of the preferred option for SH25A. 

“Work on the Coromandel will continue over the winter. We understand the impact the SH25A Kopu to Hikuai closure is having on the community, as well as the various other sites we’re working on along SH25. We’re committed to reinstating full access as soon as we possibly can. The key for us is to provide the best solution at each location that allows us to build a long-term solution quickly. 

Road users will also start to see crews proactively monitoring and maintaining roads as the temperatures drop. 

“We continuously track the weather and have plans in place for when the temperatures drop and it looks like it may start to snow, or ice may form,” says Ms Lauder. “Where we know it gets cold we use Calcium Magnesium Acetate (CMA) to prevent ice from forming on the roads, and we have processes for managing the Central Plateau when snow is on the way. 

“Our priority is always the safety of road users and our crews. This may mean that roads are closed, or travel times are slower than usual, however the most important thing is to arrive at your destination safely.

Plan ahead and take extra care while everyone gets used to the new layout. With the Bayfair flyover open and traffic volumes on Maunganui Road reduced, road reconstruction is getting underway on all ground level roads leading into, and away from, the Bayfair roundabout. To enable this work, the following temporary traffic layouts have been implemented and will be in place for approximately four months: 1) A single lane is available on Maunganui Road northbound from opposite Exeter Street, through the Bayfair roundabout to opposite Concord Avenue, 2) A single lane is available on Maunganui Road southbound from Concord Avenue to Bayfair roundabout and 3) A single lane is available around the Bayfair roundabout. Find out more about the new road layout at www.nzta.govt.nz/bayfairflyover(external link).  

    At the Bayfair roundabout, partial overnight closures will be in place either between Matapihi Road and Girven Road or between Girven and Matapihi Road. The closure will be in place from Sunday 30 April to Wednesday 3 May 2023 (from approximately 7pm to 6am, nights only) to enable upcoming road reconstruction work to be completed safely near live traffic lanes. During these hours there will be signposted detours in place via the Golf Road roundabout or the SH2/SH29A Te Maunga interchange and SH29A roundabout. In the event of bad weather or unforeseen circumstances, the closures may be moved to the next suitable night/s. More information(external link)
