SH20 Lane Closure Sunday


NZTA will close a section of the southbound lanes on SH20 on Sunday night for work associated with improvements to the Walmsley Road interchange at Mangere Bridge.

The length of the Walmsley Road on ramp is being extended by the NZTA as a safety measure to prevent  traffic using it from making quick and potentially dangerous manoeuvres across a busy motorway to reach the lanes for the airport.

Southbound drivers, including those heading to Auckland International Airport, will be diverted off the motorway at Walmsley Road to McKenzie and Kirkbride Roads.

The southbound lanes will be closed between Walmsley Road and Massey Road from 9pm on Sunday until 5am on Monday [21 March].  Northbound lanes of the Southwestern Motorway will remain open.

    This is one NZTA initiative I definitely support.

    I remember years ago being forced by a moronic taxi driver to go to the airport as he cut across 3 lanes and forced me into the airport turn off after he came on at Walmsley Rd. He simply just didn’t look or care! Reducing incidents like that can only be a good thing!
