The old bridge will be removed.
Mr Atalay said the contractors were now focused on completing work on the approaches to the new structure.
“The approaches are on track to be finished up to Te Wera in May and tied in to the south end.
“Soft ground conditions encountered at the south end of the project have required some design adjustment and the need for some further work on one of the approaches,” he said.
“However, this will not impact on the opening of the bridge to full traffic in May.”
The new bridge was designed by Hamilton-based company Bloxam, Burnett and Olliver, and the project was funded by the Crown as part of the previous Government’s Accelerated Regional Roading Programme.
