Dalton Highway Road Conditions (2021 Edition)

Last Updated on July 24, 2021 by Chris and Lindsay

It is important to know the Dalton Highway road conditions if you plan to safely drive any portion of the road. 

The Dalton Highway itself is a brutal 415-mile mixture of road conditions. The road is minimally maintained to accommodate semi-trucks.

Yet every year thousands of tourists attempt to drive the Dalton Highway. Most want to visit the Arctic Ocean at the road’s terminus in Deadhorse, Alaska.

We were such tourists that successfully completed the drive during the summer of 2018. But we had trouble in our planning. Despite all of our research we could find nothing that described the actual Dalton Highway road conditions.

We went into the drive almost entirely blind to the actual dangers of the highway. This nearly cost us on our return trip!

The Milepost offers a great reference so that you know the general sites and fuel locations along the way. Still we drove the entire 830-miles roundtrip without knowing anything about the Dalton Highway road conditions.

Whether you drive a motorcycle, car or truck, RV or even bicycle you should know the road conditions prior to leaving Fairbanks.

Be aware of the Dalton Highway Road Conditions prior to departing on your trip!

The views along desolate stretches of the highway justify the dirt roads and potholes along the way!

We advise that you download and print the ROAD CONDITIONS of the DALTON HIGHWAY PDF for a mile-by-mile record of the Dalton Highway road conditions.

NOTES:

Dirt/Gravel is maintained in periodic portions by adding water and then grading it with a motor grader. Thus the actual conditions of the Dirt/Gravel vary on a DAILY BASIS.

Frost Heaves” are bumpy portions of PAVED roads. We found it easier to drive on dirt/gravel than on paved roads with frost heaves.
