The NZ Transport Agency wishes to advise motorist that SH16 from the Port up Grafton Gully will be closed tonight, Wednesday 18 August, for emergency works.
All lanes of SH16 heading to the Southern, Northwestern and Northern motorways will be closed from 6.30pm tonight until 5am to remove an overhead gantry (under Grafton Bridge) which was damaged when it was hit by a truck carrying a container this afternoon.
Detours will be in place during this time, motorists are asked to follow the signposted routes.
The NZTA says the motorway will be closed immediately if high winds and rain pick up again, or there is further movement of the gantry.
"We are endeavouring to keep this important link open during the evening rush hour, but will not hesitate to close it if we think there is a risk to the safety of drivers," says the NZTA's State Highways Manager for Auckland, Tommy Parker. "We urge all drivers to use Grafton Gully with care."
