Interstate 70 (I-70), as it winds its way through the Rocky Mountains in Colorado, is both a marvel of modern engineering and a challenging and often dangerous highway. The main factors contributing to the danger are extreme topography, unpredictable weather, and high traffic volumes.

The highway’s elevation and mountainous terrain require steep grades and numerous sharp turns that can be challenging for motorists, particularly those not accustomed to mountain driving.

The Eisenhower Tunnel, one of the highest vehicular tunnels in the world, and the steep downgrade of the road immediately following it, known as the “Silverthorne Hill,” have both been sites of numerous accidents.

Additionally, I-70 in this region is a critical transportation corridor, and the high volume of traffic, including many large commercial trucks, can make for crowded and high-stress driving conditions.

The unpredictable and often severe weather in the Colorado Rockies also makes I-70 dangerous. Rapid changes in weather can lead to treacherous driving conditions, including heavy snow, ice, rain, and fog, all of which can reduce visibility and make the road slippery.

Avalanche risk is a real concern during the winter months, with avalanches occasionally blocking the highway. Despite extensive efforts by transportation officials to manage these risks, including the use of avalanche control and real-time road condition monitoring, I-70 through the Rocky Mountains remains a challenging and potentially dangerous route.

One of the main factors contributing to the danger is the extreme isolation. The Dalton Highway traverses some of the most remote territory in Alaska, with long stretches devoid of any services, including gas stations, hotels, or hospitals. In case of a breakdown or accident, help could be hours away. Additionally, this isolation is compounded by the harsh weather conditions.

In winter, temperatures can plummet well below zero, making any roadside emergency a potentially life-threatening situation. The highway can also become icy and treacherous, leading to extremely hazardous driving conditions.

Another major risk on the Dalton Highway is its rugged terrain. Much of the road is not paved and it features steep grades, sharp turns, and a significant amount of heavy truck traffic associated with the Trans-Alaska Pipeline System, which the highway was built to support. Wildlife crossings are also common and can pose a serious danger, especially when visibility is poor due to weather conditions or the long hours of darkness in the winter.

The few people who travel the Dalton Highway are advised to be well-prepared with survival gear and to have a firm grasp of wilderness survival skills.

Despite its dangers, the Dalton Highway offers some of the most beautiful and unique landscapes you’ll ever see. From the towering Brooks Range mountains to the vast expanses of the North Slope, it’s a place of untouched wilderness beauty. But anyone planning to drive this road should be well-prepared and understand the risks involved.
