Coasties are advised of significant lane closures on the Harbour Bridge this weekend as the New Zealand Transport Agency (NZTA) carries out resurfacing work.

Southbound lanes 1 and 2 (the clip-on lanes) will be closed from 9 pm Saturday 22 February until 12 pm Sunday 23 February, with the Shelly Beach off-ramp also shut during the works.

The scheduled resurfacing aims to enhance the longevity of the Harbour Bridge, but due to the nature of the materials used, the closure will last longer than typical overnight maintenance.

Despite the closures, traffic will still be able to cross the bridge in both directions at all times.

However, NZTA is urging drivers to avoid the area when possible, recommending State Highway 16 as an alternative route to avoid congestion.

State Highway 16, also known as the Western Ring Route, provides a detour between SH1 Constellation Drive and SH1 Manukau, using SH18, SH16, and SH20.

This detour helps maintain traffic flow while work on the bridge is in progress.

To minimise disruption, the resurfacing has been scheduled over the weekend to avoid affecting weekday commuter traffic.

However, the work is weather dependent, meaning that adverse conditions may lead to delays or rescheduling.

Motorists should plan ahead and consider using alternative routes to avoid delays this weekend.

As always, please reduce speed and follow all traffic management instructions to ensure safety for both crews and drivers.
