Lanes were closed so that the NZ Transport Agency and its partners on the Newmarket Viaduct replacement project could fill the 1.1m-wide gap between the new viaducts with concrete to make one complete structure.

Thirty-two truckloads of concrete and 40 people working in teams of six ‘stitched’ the 690m-long gap. The pour was completed ahead of schedule at 11.45pm and then the concrete was allowed to set.

Now that the stitch has been completed, work will continue to prepare the new northbound half of the viaduct for traffic. Switching traffic from the existing northbound viaduct to its improved and stronger replacement will be made in late  January.
