Motorists can expect delays next week as works start along State Highway 30 and Te Ngae Rd as part of the Eastern Corridor Stage One project.
Lane and shoulder closures and speed limit reductions will take place at multiple worksites across the eastern parts of the city.
However the New Zealand Transport Agency advised that the most disruptive work will be done at night to reduce the impact on motorists.
State Highway 30 on Sala St will be down to one lane on from Monday through to Friday between 9am and 3pm.
Contractors will be creating a service trench in the road shoulder between Marguerita St and the Puarenga Stream Bridge.
