The road link from Hawke's Bay to Taihape will be closed to daytime traffic on weekdays for three months to strengthen a bridge.
The Kuripapango Bridge, 57km from Hastings on the Napier-Taihape Rd, is set to close from Monday March 1, Hastings District Council announced on Wednesday.
It is expected to be closed during the day until May 31 as work is undertaken to get it to comply with the Government's 2016 rules that local roads and bridges need to accommodate greater vehicle weights and dimensions than previously.
During the three months of work the bridge will be closed from 9am to 6pm on Mondays and Fridays, and from 7am to 6pm on Tuesdays, Wednesdays and Thursdays.
It will be open to vehicles weighing under 22 tonnes such as cars, utes, trailers or empty trucks during the weekends and at night.
