Contractors will be working night shifts when traffic is lighter to carry out deck joint repairs on the Ngaruroro Bridge at Awatoto on SH2.
New Zealand Transport Agency spokesman Oliver Postings said the work was scheduled to be carried out over the week and temporary speed limits will be in place during the work time.
There will also be stop/go signalling.
Similar restrictions will also be in place on the northern stretch of SH2 at Morere Hill and in the Nuhaka area.
A surface repair programme is being carried out at Morere while drainage maintenance work is under way around Nuhaka.
