Motorists are advised to drive with extra care and attention this weekend as heavy rain has led to an increase in slips and flooding in the region.
The New Zealand Transport Agency has issued a warning around State Highway 30 near Rotorua, State Highway 2 Matata Straights, Waimana Gorge, and Waioeka Gorge and State Highway 35 north of Opotiki.
Motorists should expect short delays on State Highway 5 at Tumunui as the road is down to one lane and speed restrictions are in place.
Engineers are closely monitoring two cracks which have appeared in the highway with geotechnical investigations being carried out to determine the cause of the damage.
Contractors will also be making safety improvements to the State Highway network around Rotorua and Opotiki over the next fortnight.
The changes include installing safety rails, new road marking, and tree trimming to improve visibility. Speed restrictions and other traffic management will be in place at times on State Highway 36 at Hamurana, State Highway 30 Lower Atiamuri, State Highway 5 Mihi, State Highway 2 Opotiki, and State Highway 35 Opape.
Speed restrictions and stop/go traffic management will also be in place on highways around the Eastern Bay of Plenty this month as contractors continue an annual water cutting programme.
Water cutting with a high pressure water jet removes areas of excess bitumen that have appeared during the hot weather over summer. It helps to improve grip and prolong the life of the road. Work is continuing on State Highway 2 from Waiotahe through to the Waioeka Gorge.
People should expect minor delays and are urged to drive carefully through the work sites.
