The Mangatewainui Bridge on State Highway 2 south of Norsewood is down to one lane due to cracking on the bridge deck.
Waka Kotahi NZ Transport Agency said despite the cracking, the bridge remained safe for use by traffic.
Stop/Go traffic management with a temporary speed limit of 30km/h is in place, and a spokesperson said contractors may look to install temporary traffic lights to control the flow of traffic later this week.
Contractors expect to repair and reseal the bridge later this week or early next week.
The spokesperson said once the seal has set, the bridge will reopen to two lanes.
