Storm repair work update

2 Jun 2020

Things are going well on repairing major  damage left in the wake of a huge rain storm that struck the Milford Road in early February. 

The worst hit area is between the Hollyford Valley turn-off through to Milford Sound Piopiotahi, with damage at several sites along 25km of remote country with no phone, power or facilities. The large sites needing complex repairs are mostly contained in the Hollyford Valley.

Downer NZ were the logical choice to carry out the storm repairs with their extensive knowledge of the Milford Road, skilled staff and easy access to the right construction plant for a challenging job.

Good progress is being made on the design work and consenting needed before work can start on larger scale repairs to damaged retaining walls and bridges. The overall project has an estimated cost of $9 million and will continue for at least the next 12 months.

Please note: While the road is now open 24/7, it’s still subject to weather and other closures or restrictions needed from time-to-time to ensure the safety of all road users.

Why Milford Road is so important

The Milford Road provides the only road access to one of New Zealand's favourite tourist attractions – Milford Sound Piopiotahi. No other highway in New Zealand climbs as fast to the same altitude as this one which at its highest point is 940 metres above sea level.

History of Milford Road

Those who built the Milford Road and the Homer Tunnel in the 1930s were, for the most part, victims of the Great Depression and directed to this work by the government of the day. For these men of the road, and their wives who followed them into this wilderness, life was incredibly harsh, but the road and tunnel had to go through.

The weather could be merciless, the terrain ferocious, steep and rugged and beset by floods and deadly avalanches. Some workers died; bridge structures, road works and tunnel portals demolished, by the irrepressible forces of nature that marauded this area. In 1952 the road was finally completed. However, it remained closed during winter until the late 1970s, when tourist and fishing interests successfully lobbied for the year-round operation of the road.

After a massive avalanche killed a road maintenance supervisor in 1983, a programme was developed to monitor, assess and control the avalanche risk on the Milford Road. This avalanche control programme enables the road to stay open as much as possible with optimum margins of safety for all road users.

Avalanche hazard

The avalanche hazard is the prediction of the probability of avalanches happening and is expressed as a level of danger. You must consider this before driving into the avalanche area.

The avalanche hazard forecast is compiled from information that includes existing avalanche start zone snow-pack conditions (snow pit studies), current weather data (from automated road and high-level weather stations, that transmit data from the mountain top), the weather forecast and local knowledge of avalanche activity.

When a low avalanche hazard is posted on information signs on the Milford Road, the road is open. If a moderate avalanche hazard is posted there is a risk of avalanches reaching the road and the road could be closed at any time. When a high avalanche hazard is posted the road is closed.
