The NZ Transport Agency advises motorists that State Highway 16 in Auckland will be closed between Lincoln Road and Westgate from 8pm Saturday to 5am Sunday morning.
Huruhuru Road Bridge across the motorway will also be closed to vehicles.
The closure is to allow a concrete pour to “stitch” or join up the deck on the new Huruhuru Road bridge. The old structure was demolished in January after half of the new bridge was completed. Traffic was moved on to the new bridge while the remaining span was built.
The motorway and bridge will be closed all night to allow time for the concrete to set with no exposure to vibrations from passing traffic. Pedestrians, cyclists and emergency vehicles will be allowed across the bridge.
The Royal Road bridge, just 1.5km up the motorway, will get the same treatment next month.
The two bridges are being upgraded to include shared paths for cyclists and pedestrians, increased height clearance from the motorway and wider lanes for traffic.
The SH16 Lincoln Road to Westgate project will improve the Northwestern motorway to support the expected growth in the western suburbs and increased traffic using the Western Ring Road.
Benefits include more lanes and dedicated bus lanes to manage traffic and provide more reliable travel times. There are more walking and cycling facilities with the northwestern cycleway extended to Westgate. The new bridges at Royal Road and Huruhuru Road improve safety and access to the motorway.
