Eyre Highway: the 240-kilometre, uncurvy road through the Australian desert

Among the most unique routes in the world is a stretch of road that stands out for its unusual geometry: a straight line of approximately 240 kilometres with no significant deviations. This route is located in Australia and is often mentioned as an obligatory reference when discussing which is the straightest route on the planet.

Where is this long straight road located?

The section is part of the Eyre Highway, a highway linking Western Australia with South Australia. Its route crosses the Nullarbor Plain, one of the driest and least populated areas of the Australian territory. The region’s name comes from Latin and literally translates to “treeless,” a description that accurately reflects the landscape: completely flat terrain, sparse and low vegetation, and a sense of emptiness that stretches to the horizon.

Within this highway is the segment that gave it international fame: around 146 consecutive miles, equivalent to about 240 kilometers, without a single relevant curve. It is precisely this characteristic that has made the place a point of interest for both drivers and land travel enthusiasts.

Origin and function of the Eyre Highway

The construction of this highway responded to a practical need: to connect distant regions and facilitate the transport of goods between isolated areas of the country. As time went on, however, the route acquired additional value as a tourist attraction for those who decide to cross Australia by car or motorcycle.

The geographical context differentiates it from other similar roads in the world. The combination of extreme desert, total isolation and an almost perfectly straight line generates a scenario that many travelers describe as an unforgettable experience, although also demanding.

Other roads in the world with long straight stretches

The question of which is the straightest route on the planet has been the subject of debate for years. A number of countries have remarkably long and straight motorways, although they do not always share the same geographical conditions or continuity.

• Saudi Arabia: it has extensive stretches through desert regions.
• United States: Highway 50 in Nevada, known as “the loneliest road in America,” crosses nearly unpopulated areas for hundreds of kilometers.
• Canada: has several long routes in prairie areas.

Most of these alternatives, however, feature small curves or slight changes of direction that interrupt absolute continuity. For that reason, the Eyre Highway continues to hold a prominent position in this type of comparison.

What is involved in driving on the Nullarbor plain

Traveling this stretch does not resemble a conventional trip. The conditions of the environment impose a particular dynamic that forces drivers to prepare in advance. Some of the main aspects to take into account are:

Loneliness on the road

It is common for several minutes to pass without another vehicle crossing. This solitude can be imposing for those who are used to routes with frequent traffic.

Distances between services

The service stations are very far apart from each other. For this reason, drivers usually fill up with fuel earlier than necessary, carry supplies of water and food, and check the condition of the vehicle before starting the journey. A breakdown in the middle of the desert can become a complicated situation.

Demanding climate

During the summer months, temperatures in the region can easily exceed 40 degrees Celsius. The extreme heat on the asphalt generates mirages that give the appearance of puddles or layers of water on the road, a visual phenomenon that can baffle those who are not used to it.

Eye strain

The absence of curves and the constant repetition of the landscape can cause drowsiness and mental fatigue. The lack of visual references means that the brain receives few stimuli, which increases the risk of microsleeps at the wheel. For this reason, it is recommended to make frequent stops and, if possible, travel accompanied to take turns driving.

A destination that combines engineering and extreme landscape

The popularity of the Eyre Highway on social networks and specialized forums is due, to a large extent, to the mixture between curiosity about the engineering work and the attractiveness of the landscape. Images taken at the site show how the asphalt merges with the horizon, generating a visual sensation that some describe as surreal.

For lovers of road trips, crossing Nullarbor represents an experience unlike any other: a journey where time seems to stand still and where planning, patience and respect for the conditions of the environment become essential to reach the destination safely.
