Upgrading highway safety and maintenance programmes across several Hawke's Bay highways will mean travel delays, and warnings from the NZ Transport Agency to drive with caution where contractor vehicles are operating.
Some crews are also continuing to remove the last patches of debris from slips on parts of State Highway 2 north between Bay View and Kotemaori.
Temporary speed restrictions have been put in place in those areas along with stop-go signalling, and motorists can expect to add about five minutes to their travel times.
There are also likely to be delays around the Nuhaka area of the highway as contractors continue repair work on the Tahaenui Bridge.
A traffic-light control system has been put in place.
