24 beams were successfully lifted into place across the span of the Hobsonville Road Bridge this month signalling another successful milestone of winter construction on the SH18 Hobsonville Deviation and SH16 Brigham Creek Extension project.
Contractors worked over four nights to lift each 36 metre concrete beam and place it on top of the piers of the bridge with a 300 tonne crane. The beams were manufactured at Stahlton - a local pre-cast yard in Swanson and trucked to the site.
The Northwestern Motorway (SH16) lanes from Royal Road to Hobsonville Road were closed overnight and motorists followed detours on local roads so that the work could take place. Construction of the bridge is taking place in the middle of the signalised roundabout while live traffic travels around it.
The next stage of work to complete the bridge, relocate the services and widen Hobsonville Road will take place over the next four months. The six lane bridge is scheduled to be completed in late November and forms part of the Hobsonville Road Interchange with SH16. The new interchange will replace the existing at grade intersection of Hobsonville Road and SH16, near Westgate.
“We thank drivers for their patience and co-operation while construction continues on this key northern link of the Western Ring Route,” says NZTA Acting Regional Director for Auckland and Northland Tommy Parker.
Work is also progressing on the Trig Road Bridge to complete the bridge deck itself and finish the footpaths. Services are also being installed for telecommunications, water and power. Trig Road will then be realigned and a new road surface laid before the bridge opens in mid October.
At the other end of the new motorway, preparations are also underway to shift motorists onto two new lanes south of the current state highway at Monterey Park. Traffic will move onto this new section of road in October so that earthworks can continue on the Squadron Drive Interchange.
