In the wake of the Basin Bridge decision an alliance has been established between Wellington City Council, the Transport Agency and Greater Wellington Regional Council to develop an integrated multi-modal solution for Wellington’s transport needs. The focus is the area from Ngauranga Gorge to the Airport, encompassing the Wellington Urban Motorway and connections to Wellington Hospital and eastern and southern suburbs.

Called Let’s Get Wellington Moving (external link)(external link) this alliance has a programme to develop and consult on recommended scenario/s by early 2017.

While this is being progressed, all previously planned improvements on key parts of the network have been placed on hold, including the Mt Victoria Tunnel Duplication project.

Background

  • Key features of this project

    The duplication will strengthen the strategic link between the Airport and the urban motorway, providing greater route reliability and enhancing Wellington’s transport hierarchy, thus facilitating the reallocation of road space in the CBD for public transport and pedestrians.

    Other facts

    The length of the tunnel is approximately 0.5km, increasing to 2km when the entry approach and exit connections are included.

    Current work

    To help us understand what approach to take to make improvements at the Terrace Tunnel, we need to know what the underlying ground conditions are like so we need to do some geotechnical investigations. Work is planned to take place from mid-July in several spots on the southern side of the existing tunnel and will take roughly three months to complete. Work is specifically planned in the area of The Terrace, Salamanca Road, Willis Street, Karo Drive, Dixon Street, Macdonald Crescent and Ghuznee Street so you may see equipment, support vehicles and contractors on or around these areas until later this year.

    Work is as an early stage, but we expect we might want to duplicate the existing tunnel. This would address congestion at this bottleneck approach to the CBD and would result in better peak hour travel on both the highway and local roads.

    We expect to have more details on how we can best improve travel in, through and to Wellington with a duplicate Terrace Tunnel later this year and will be keen to get community and public feedback.
