On Monday, the first five of 14 reinforced concrete bridge beams will be placed across State Highway 2 at Haywards interchange, Upper Hutt.
NZ Transport Agency highway manager Neil Walker says State Highway 2 will be reduced to one lane each way, just north of State Highway 58, from around 6.30pm.
The placement of the beams will require a series of rolling approximately 15-minute road closures on the highway from 10pm through the early hours of Tuesday morning.
The construction team will be placing the 32m, 70 tonne beams from 10pm to form the first of two traffic bridges across the highway. The second bridge will be formed in late August or early September.
“We’ve timed the lifts to minimise disruption to traffic. An alternative route will be available and well signed. The alternative route is not suitable for large vehicles, which will need to wait for the short time that the road is closed,” says Walker. He adds that only high winds could prevent the bridge beam lifts going ahead.
Most of the beams will be used to construct the bridge at the intersection, while four will be used for the pedestrian overbridge linking Annabell Grove to Manor Park railway station.
The interchange is expected to be complete in June 2017.
