NZ Transport Agency crews will be starting on Monday, running through to March 14.
The bridge is close to the Ophir Bridge Rd junction.
Close to 600 metres of highway needs to be replaced, from the eastern end of the Thomsons Creek Bridge to about 40m south of the Wilton St/State Highway 85 intersection.
This work to fully reconstruct the road surface to give good traction and improve safety is weather dependent. Dates could vary if it is wet or cold, NZTA Central Otago maintenance contract manager Peter Standring said.
Drivers will face delays of up to 10 minutes as one lane of the road will be tackled at a time and traffic managed with stop/go, with speeds down to 30kmh.
Crews will be on site from 7am-6pm each day on weekdays.
Outside of these hours, the road will be unattended with speeds reduced to 30kmh and open both directions.
