Motorists travelling south on State Highway 2 should prepare for delays at night, as rock scaling work will be carried out at Devils Elbow.
The Transport Rebuild East Coast (TREC) crews will be present at Devils Elbow and later at Waikoau Hill from next week until the end of June.
A NZTA/Waka Kotahi spokesman urged road users to plan for delays while the work takes place overnight.
“Crews will begin their work at Devil’s Elbow from this Sunday, working six days a week between 8pm and 5am.”
The rock scaling work will begin at Devils Elbow on Sunday and will continue for three weeks, with completion expected by the end of May.
