Unusually high tides could flood motorways

The Transport Agency is warning of the potential for unusually high tides to flood parts of Auckland's motorway system in the coming week.

The agency says tide peaks of up to 3.6 metres are expected from Monday until Friday for the Manukau and Waitemata harbours.

A spokesperson, Tommy Parker, says while the tides will definitely have some impact on low-lying sections of motorway, they won't pose a significant risk to safety.

He says the areas most likely to be affected are sections of the road and cycleway on the Northwestern Motorway between Patiki Rd Interchange and the Rosebank Rd bridges.

Mr Parker says the cycleway will definitely be under water when the tide peaks.
