Motorists are facing delays on State Highway 3 between Stratford and New Plymouth over the next couple of months.
Waka Kotahi New Zealand Transport Agency says road maintenance is taking place at a number of sites on SH3 between Midhirst and Inglewood. There will be delays in each direction.
Light southbound traffic will be detoured from the intersection of SH3 and SH3A in Inglewood to SH3 at Beaconsfield Rd in Midhirst via Tarata, Kaimata and Salisbury Rds.
Salisbury Rd between Croydon and Tariki Rd South will be one lane, open to southbound traffic only. Southbound freight and haulage will use SH3 via convoy from Durham Rd every two hours, or State Highway 45.
There is a number of different times during the day that SH3 northbound is open for all vehicles from Tariki.
