Construction periodMay 2013 - December 2016

The fast lane to total mobility

Economy: Leighton is widening a highway near Auck­land by 2017. The causeway upgrade is a 4.5 kilome­ter-long project between the Great North Road Inter­change and the Te Atatu Interchange, and is a key component in completing the Western Ring Route road of national significance project. The existing six-lane causeway will be widened to provide additional lanes in both directions.

Ecology: The causeway will be raised to prevent flooding during extreme tidal conditions, and stormwater will be treated to a higher standard before it is discharged into the Waitemata Harbour. The causeway runs be­sides the Motu Manawa – Pollen Island Marine Reserve. Design data has been gathered during the causeway trial to ensure that the Causeway Upgrade will have as little impact on the Marine Reserve as possible.

Community: The causeway will improve traffic flow and travel times, including quicker bus trips and improved pedestrian and cyclist access across the motorway.
