Mount Victoria Tunnel (Wellington)

The Mount Victoria Tunnel in the capital city of Wellington; New Zealand.

The tunnel is 623 metres (slightly more than a third of a mile) long and 5 metres (16.4 ft) in height, connecting Hataitai to the centre of Wellington and the suburb of Mount Victoria.

The tunnel was built in 15 months by the Hansford and Mills Construction Company. The project cost around £132,000 and greatly reduced travel time between the Eastern Suburbs and the central business district of Wellington. Construction employed a standard tunnel-excavation technique in which two teams of diggers begin on either side of the obstacle to be tunnelled through, eventually meeting in the centre.

The initial breakthrough, when the two separate teams of diggers met, occurred at 2.30pm on 31 May 1930, and the first people to pass through the breakthrough were tunnellers Philip Gilbert and Alfred Graham. The tunnel was opened officially by the mayor of Wellington, Thomas Charles Hislop, on 12 October 1931.

Although the tunnel has been eclipsed in terms of features and amenities by more recent tunnels around the country, such as the Terrace Motorway Tunnel.

The Mount Victoria Tunnel was the first road tunnel in New Zealand to be mechanically ventilated. Around 45,000 vehicles pass through it each day. The tunnel also accommodates pedestrians and cyclists, who use an elevated ramp on the north side of the roadway. In the late 1970s, a number of crime incidents resulted in an alarm system being installed based on buttons spaced along the length of the pedestrian ramp - the system was removed several years later, as it proved ineffective. Recent additions include new lighting, CCTV cameras, brighter cleanable side panels and pollution control. These have significantly improved safety in the tunnel.

There has been a long standing designation for a second parallel tunnel to the north, in order to relieve peak period congestion resulting from lane merges at both ends of the tunnel. A pilot tunnel was bored through in 1974 to investigate the technical feasibility and still exists, although the eastern end has been bricked up and the western end lies on private property. Plans to build the second tunnel paralleled the original plan to complete the Wellington Urban Motorway to the tunnel to provide a motorway bypass of the whole of central Wellington. The second tunnel component was shelved indefinitely in 1981 when budget cuts meant that a scaled-down motorway extension was proposed that would terminate at the existing tunnel.

Since that date there have been no serious proposals to duplicate the existing tunnel, although cost estimates for such work were at $40 million in the mid 1980s. Traffic lights have been installed at the end of the city approach to the tunnel to ease congestion and improve safety at the Basin Reserve roundabout. There are no plans in the next ten years to duplicate the tunnel, but plans to investigate work to upgrade the city approaches around the Basin Reserve, including a possible flyover to Buckle Street, to reduce congestion at the city end of the tunnel and around the Basin Reserve. A study is currently underway (the Ngauranga to Airport Study) investigating long-term transport options for the route. The study indicates that a new tunnel would cost around (NZ)$170 million.

The tunnel currently is a traffic bottleneck in the morning peak from around 7.30 to 9.00am on the Hataitai side with traffic sometimes backing up over 1 km and in the afternoon peak between 5 and 6pm on the city side with queuing back around 0.5 km. Buses to the eastern suburbs bypass this congestion by using the much older single-lane Hataitai bus tunnel.

Trivia
During World War II, the government planned to use the tunnel as an air raid shelter if Wellington was attacked. However, the plan was scrapped as the tunnel was thought to be too vulnerable to assault from either side by hostile troops.

A well-known local story revolves around a murder that occurred during the construction of the Mount Victoria Tunnel. A young woman named Phylis Simons was murdered by her lover, who buried her alive in the fill from the tunnel. It is suspected that the girl was pregnant to her lover and the story was later covered in the Wellington newspapers. Upon learning of the murder, police ordered workers to excavate the tunnel's fill in order to find the victim's body.

The tunnel is well known in Wellington as being the location of "the beeping game", in which motorists sound their horns as they go through the tunnel, often in response to the tooting of other drivers. This is particularly popular after 5pm on Friday nights.

Local legend traces the tradition of beeping in the tunnel to the period soon after it was completed, when most of the traffic through the tunnel was pedestrian. The few cars that passed through the tunnel would beep at the young people walking through. The young pedestrians carried on this tradition after the second world war, when cars became more common.
