The Western Rd detour at the State Highway 5/SH36 roundabout near Ngongotahā will be removed Monday.
Waka Kotahi NZ Transport Agency said work was planned to take place on Sunday night to reduce impact on traffic and will involve the removal of the detour and partially opening the roundabout by 6am on Monday.
The roundabout will remain a construction zone with traffic management in place while contractors apply final surfacing, complete the slip lanes from Ngongotahā to Rotorua and Rotorua to Hamilton, and finish line marking, concrete footpaths, driveways and landscaping.
These works require the roundabout to remain single lane in each direction for the next three weeks, weather dependent.
There will be a 50km/h temporary speed limit through the roundabout. The two temporary roundabouts at Western Rd and in Ngongotahā may remain in place for a few days until the weather allows for removal of line-markings.
