The NZ Transport Agency says stop/go traffic management will be in place on roads in the southwest Waikato from next week as contractors roll out a 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.
Transport Agency contractors will be working at around 230 different sites in the Waitomo, Otorohanga and Waipa districts over the next four weeks.
The stop/go traffic control will be in place to allow crews to work as quickly and safely as possible while keeping delays to road users to a minimum. Work at each site takes around an hour to complete.
Water cutting will be gradually rolled out around the rest of the Waikato region in the coming months.
Other construction and maintenance work continues at sites around the region and motorists are advised to drive with care and allow for delays when travelling.
Sites where delays are possible are detailed below to allow motorists to plan ahead when travelling.
The Transport Agency apologises for any inconvenience and thanks motorists for their patience.
