The NZ Transport Agency says that the Constellation Drive northbound off-ramp will be closed tonight for emergency works to repair a guardrail after a crash caused extensive damage.
To minimise disruption to road users, the closure will be timed between 9pm and 5am when traffic flows are lighter.
A signposted detour will be in place and motorists are asked to follow the signposted routes while work the work is being carried out.
This will ensure everyone using and working on this section of the motorway stays safe.
