Work has started on the Kuripapango Bridge, with stock trucks and pregnancies just some of the many issues facing Rangitīkei residents because of its partial closure.
"A lot of produce goes over that road, a lot of fertiliser comes from Napier across into Rangitīkei, a lot of wool, red meat and forestry can come back this way," said Hastings Deputy Mayor Tania Kerr.
"This is a key route not only for our primary produce but also for our tourism. And access - access for our Hawke's Bay people to get across to the central North Island."
The bridge sits on the only road between Hastings and Rangitīkei Districts.
It will spend the next three months closed during business hours as the Kuripapango Bridge undergoes strengthening work.
Until the end of May 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.
