Travel directions

Copper River Highway

The Copper River Highway begins on the south coast of Alaska in the port town of Cordova. The road heads east along the coast. The route is extremely spectacular, glaciers reach almost to the road and the road crosses the meltwater rivers. The road is relatively flat and has a number of bridges. The road gradually curves north and ends at the Million Dollar Bridge. The road is only asphalted at Cordova.

Edgerton Highway

The Edgerton Highway begins 100 miles north in Chitina as the crow flies, connecting that village to the Alaskan road network. The road runs northwest along the Chitina River to State Route 4 south of Copper Center. The road is asphalted.

Not much is known about the history of Route 10. In 1910, the Million Dollar Bridge opened. This was originally a railway bridge, but was converted into a road bridge in 1958. During the great earthquake of 1964, the Copper River Highway under construction was damaged.


The idea is sometimes played with to connect the two parts of Route 10, so that Cordova can also be reached by road.

Traffic intensities

Every day 4,200 vehicles drive in Cordova, outside of that less than 100 vehicles drive on the Copper Highway. Between 150 and 500 vehicles travel on the Edgerton Highway.

State Route 3, administratively numbered as Interstate A4 and known as the George Parks Highway, is a state route and partial freeway in the U.S. state of Alaska. The road forms a north-south link from Gateway to Fairbanks. The road leads through Denali National Park. State Route 3 is 520 kilometers long.

Travel directions

At Gateway, the road begins on the Glenn Highway, State Route 1 that runs as a freeway to Anchorage. The highway is 7 kilometers long and ends on the outskirts of Wasilla. This area is quite densely populated. The road heads west for a bit, then follows the Susitna River to the north. The first 20 kilometers still leads through somewhat cultivated area, but further north the road leads mainly through uninhabited wilderness. The wide valley of the Susitna River narrows to the north and the Alaska Range looms, with the 6,168-foot Denali being the highest point in both Alaska and all of North America. However, the mountain is often shrouded in cloud. State Route 3 remains at least 55 kilometers away from this mountain. The glaciers of the mountain range reach closer to the road.

Further north at Cantwell, State Route 8 joins. The road then crosses the Alaska Range through a narrow valley. The mountains immediately surrounding the road are approximately 2,000 meters high. Further north, one comes to a flatter area in the interior of Alaska. At Nenana, one crosses the Tanana River, whereupon the road bends east and follows the river for some distance to the town of Fairbanks. The road then ends in Fairbanks as a 2×2 divided highway. State Route 3 connects with State Route 2 at a grade separated level.


The George Parks Highway connecting Anchorage and Fairbanks is one of Alaska’s most important highways, but it was developed late. The historic north-south route went eastward via the SR-2, SR-4 and SR-1 over Delta Junction, which was already passable by motorized traffic in the 1920s. State Route 3 was not completed until 1971 as a direct route from Anchorage to Fairbanks. It was also of great importance for tourism, as it is the only thoroughfare to Denali National Park.

Although State Route 3 begins in Gateway, the milestones begin in Anchorage, traveling first on the Glenn Highway (SR-1) to Gateway where SR-3 begins.


There has been talk for years about a possible ” Kink Arm Bridge ” over the Cook Inlet north of Anchorage. This would shorten the distance from Anchorage to Fairbanks by approximately 40 kilometers.

Traffic intensities

29,000 vehicles drive daily on the highway at Gateway, which increases slightly to 31,000 vehicles in eastern Wasilla and 30,000 vehicles through Wasilla. This gradually drops to 4,200 vehicles south of Willow and 2,900 vehicles north of it. The quietest part between Wasilla and Fairbanks has about 1,000 vehicles per day. This gradually increases to 4,000 vehicles west of Fairbanks and up to 16,000 vehicles in Fairbanks.
