Work has started on a $25 million safety upgrade of Southland’s Homer Tunnel on SH94, providing a welcome economic boost for the Te Anau and Milford Sound Piopiotahi communities, says Waka Kotahi NZ Transport Agency.

The Government announced the funding for this project in July this year, to improve the safety and resilience of the Homer Tunnel, which opened in 1953.

Waka Kotahi’s Milford Road Alliance has now begun $3 million worth of “shovel ready” smaller safety improvements that came out of recommendations of an investigation into a car fire in the tunnel at the beginning of 2020.

Work completed so far includes an upgraded tunnel power system and lighting.

New speakers have been fitted inside the tunnel to communicate with people caught there in an emergency.

A new protected duct is also being built along the full 1.2km length of the tunnel to protect cabling, fibre and other systems during a fire.

Waka Kotahi System Manager Graeme Hall said over the next year, an extra lane will be built at the eastern tunnel traffic signal (back toward the tunnel control building) for better management of traffic during winter.

A more sophisticated in-tunnel vehicle detection system would also be installed. 

The remaining $22 million safety funding will pay for one of the following: pedestrian refuges (for people to escape a fire), a forced ventilation system (to reduce a fire spread) or a deluge system (to limit and contain a fire). 

“Whatever option is chosen it will be large and complex work needing significant design, consenting and other approvals, and is likely to be delivered over a two to three-year period,” Mr Hall said.
