Road repairs, new construction work and a tree-felling programme in the Devil's Elbow region of State Highway 2 north will mean a string of delays for motorists using the stretch.
NZ Transport Agency spokesman Oliver Postings said the tree felling work was now under way adjacent to the highway around the top of the Devil's Elbow.
When felling was taking place there would be stop-go signalling in place, along with speed restrictions.
Temporary speed restrictions are also in place at four other works sites along the highway between Napier and Wairoa.
Construction of a new passing lane between Bay View and Hawke's Bay Airport is continuing and lane shifts, pushing traffic to one side of the road, are in place.
