Karori Tunnel will be safer, more accessible for pedestrians, and subject to fewer leaks after improvement work in early 2019.
The improvement work by Wellington City Council is in response to ongoing feedback regarding the concerns of residents and users of the tunnel, which was built in 1900 and is Wellington’s oldest road tunnel.
The council completed essential earthquake-strengthening work on Karori Tunnel in 2013, as an assessment of the tunnel showed that the portal walls at the tunnel entrances and nearby slopes were likely to suffer significant damage in a major earthquake. The work was part of the Council’s ongoing programme to strengthen important transport routes and earthquake-prone structures.
The improvement work next year will affect vehicle and pedestrian access to the tunnel.
Around 114,000 vehicles pass through the tunnel each week.
Diversions will be in place, and more information will be available nearer the time.
