State Highway 94 is a New Zealand state highway connecting the large Southland town of Gore with one of New Zealand's most popular destinations, Milford Sound. It also passes the significant townships of Lumsden and Te Anau as well going through the Homer Tunnel (in this area it is also called the 'Milford Road', with the section from Te Anau up to the Sound being 119 kilometres or 74 miles).^[1] The road also goes through Fiordland and crosses the Main Divide of the Southern Alps.

It is regarded as one of the most scenic roads in New Zealand, and with a peak elevation of 940 metres (3,080 ft), the country's third highest highway after the Desert Road (SH 1) and the Lindis Pass (SH 8).^[1] However, the "Milford Road" part is also one of the more dangerous public roads in New Zealand, with injury crash rates around 65% higher than the rest of New Zealand's network, and a fatality crash rate of almost twice average (per vehicle kilometre travelled),^[2] making it the third most dangerous section of New Zealand's State Highway network (as of 2008).^[3]

The road alignment was first surveyed in 1890 by London-born engineer Robert Holmes, who later became the Engineer-in-Chief of the Public Works Department. Holmes initially preferred a route starting at Lake Wakatipu and running northwest, but the decision was instead made to start from Te Anau.^[1]

However, the project then languished in planning for 40 years, possibly because in 1889 road building had been removed from the brief of the Public Works Department, and only reinstated with much more limited authority in 1909.^[1] It took until 1935 to construct a rough road to the entrance of what would become Homer Tunnel.^[1] The tunnel itself was excavated by pick and shovel, mostly by workers directed there by the government during the Great Depression. Life for the workers was harsh, and avalanches claimed some lives in the mid 1930s.^[4] While the breakthrough was achieved in February 1940, the labour shortage caused by World War II caused significant delays, and it was not until 1953 that the tunnel was finally completed.^[1]

Long stretches of Milford Road, including the tunnel, remained gravel-surfaced until the 1980s. Improvements to the Homer Tunnel portals are ongoing and remain on the NZ Transport Agency's plans, with the aim of reducing closures of this important tourist route.^[5] The latest construction project to minimise the impact of avalanches was an extension of the western tunnel entrance portal.^[6]

As of 2020, this is the route SH 94 takes.^[7]

The Milford Road section began in 1926 when a local Station Owner, started making his own road from Te Anau Downs Harbour south to the Te Anau Hotel, starting a project which turned into the most scenic highway in New Zealand including iconic landmarks the Mirror Lakes, the Avenue of Disappearing Mountain, Lake Gunn, the Key Summit, Mount Christina, Mount Talbot, the Homer Tunnel, The Chasm, Mount Tūtoko and Mitre Peak. Before the sealing of the road in the 1980s, it was treated as a day's adventure from the township of Te Anau and Milford Sound the climax of the journey. Modern marketing and faster buses have made Milford Sound a destination from Queenstown involving 8 hours of bus transit, a round trip with few stops. This route is part of the Te Waipounamu Wilderness Area.

The Eglinton Mountains above Lake Gunn were used as a location in the Peter Jackson movie The Fellowship of the Ring where the actors walk along a mountain path with the Key Summit evident in the distance. The mountains here were also used in the Fellowship of the Ring introduction to represent the Misty Mountains. Emily Peak on the Routeburn Track can also be seen in this movie, as well as the Mavora Lakes near Mossburn. Ironically, Peter Jackson picked an area that once contained New Zealand's only place names from J. R. R. Tolkien that was removed from the official maps in the 1980s, as they were deemed inappropriate for this region.^[11]

There are many places of Local History not signposted by Transit New Zealand, such as the Cleddau Horse Bridge, the Hollyford Hydro Powerstation remains, the Old Homer Tunnel construction village site, however, Transit New Zealand has kept the historic White Mile Posts that are a feature of the early days of the Milford Road Construction. The Department of Conservation has kept up the Latitude 45 South Marker but has abandoned the Avenue of the Disappearing Mountain to history as the avenue of trees beside the Road has become overgrown.

Car parks are located at popular stopping points for tourists along Milford Road, such as Mirror Lakes, The Divide (western end of the Routeburn Track), the eastern portal of Homer Tunnel (access to a short loop track), and The Chasm (short walking track to a waterfall).

Outside of the Milford Road, Mandeville is the site of the Croydon Aircraft Company Link, and the local aerodrome is home to several rare vintage aircraft. Mossburn is the closest settlement to the Mount White Wind Farm which at full capacity can power almost all the entire Southland region. The Ōreti, Mataura and Waiau Rivers that dominate the flatter regions of SH 94 between Gore and Te Anau are popular fishing spots for brown trout. Care should be taken while fishing to prevent the spread of Didymosphenia geminata.^[12]

Tourists to Milford Sound arrive mainly via coach over the length of SH 94 from Mossburn, a predominantly high mountain road which is prone to avalanches in winter. The road was only opened in 1953, after the Homer Tunnel was finished, after almost 20 years of intermittent work. The road is one of the more dangerous public roads in New Zealand, with injury crash rates around 65% higher than the rest of New Zealand's network, and a fatality crash rate of almost twice average (per vehicle kilometre travelled),^[2] making it the third most dangerous section of New Zealand's State Highway network (as of 2008).^[3] Stopping is prohibited on long stretches due to rock or snow avalanche dangers, and the road is often closed in winter, with the carrying of snow chains mandatory during snow conditions. Helicopters are used during winter to drop explosives onto snow buildup zones above the road in order to cause controlled avalanches. However, this does not eliminate the danger that road traffic may be hit by an uncontrolled event, especially in the area of the Homer Tunnel portals.^[2]

There are no petrol stations on the length of the road from Te Anau to Milford Sound, meaning that vehicles need to take enough fuel for a return trip. All of this does not discourage up to 50 coaches and hundreds of private cars daily from making the 546 km trip from the nearest city Invercargill, and the 572 km trip from popular tourist destination Queenstown. Almost 60% of tourists travel via coach, which is regarded as being safer than attempting the road on your own.

Avalanches are a winter hazard in the high mountains above the Milford Road and snow and ice affect the road surface in the winter months; transit signs inform motorists of conditions and a Transit New Zealand check point has been built to make sure road users carry chains for safe passage to Milford Sound. Metal gates are positioned across the Milford Road in the Hollyford and Cleddau Valleys when the road is closed at times of peak avalanche probability. The road is closed an average 8 days a year, mainly during the winter months, when the entire length of SH 94 is susceptible to snowfall.^[13] Snow can fall on higher parts of the road any time of the year, and due to the nature of the Fiordland environment, the road can be closed at any time of year from landslips, treefalls and washouts. Care should be taken year-round, especially on the hillier regions between Mossburn and Milford Sound. Flooding can also occur at any time along the road especially around rivers.

Building the Milford Road section of SH 94 has been a classic story of danger, hardship and Kiwi ingenuity in the Depression Years and has been the subject of several books: Harold Anderson's 1975 Men of the Milford Road, a detailed account of the project from his perspective as a Public Works Department Paymaster;^[14] Wilson Campbell's 2000 Novel When stars were brightly shining about a fictional murder in one of the works camps;^[15] John Hall-Jones's, Milford Sound An Illustrated History of the Sound, the Track and the Road, which covers in detail the history of the road with ample historic photographs;^[16] and Amy McDonalds 2005 Below the Mountains, a young girl's diary of living on the Milford Road 1935 to 1936.^[17] And there are mountain climbing books that cover this area in detail, such as Jack Ede's 1988 "Mountain Men of Milford"^[18] and Anita Crozier's 1950 Beyond the Southern Lakes.^[19]
