Accompanied by pilot vehicles more than 14 reinforced concrete bridge beams will be making the overnight journey by truck from Auckland to Wellington over the coming weeks.
The first beams have arrived at the State Highway 2/State Highway 58 Haywards interchange project site.
NZTA highway manager Neil Walker, says the Agency’s operations centres will be in regular contact with the truck driver, to ensure minimal disruption to other road users during the beam delivery.
“We’ll be monitoring progress down the country, through contact with the driver and by using the cameras on the highway,” says Walker.
“Transporting enormous and long loads such as these bridge beams requires careful planning and co-ordination,” he says.
The 14 beams are each 32 metres long and weigh 70 tonnes.
Ten beams will be used to construct the elevated roundabout at the intersection, while four will form the basis of a pedestrian overbridge linking Annabell Grove to Manor Park railway station.
Current planning is to begin lifting the beams into place on the night of Monday 15 August, although this will depend on the weather.
More information about the beam lifts will be provided closer to the time, including details of traffic management and possible delays to journeys in the area.
The beams for the pedestrian bridge will be transported down the country and installed in October.
