With the exception of Hawaii, you can drive from anyplace in the US to Alaska. For the quickest route, use
mapquest directions. The only major route connecting Alaska to the rest of the country is the Alaska Highway. No matter where you start in the US or Canada, you will eventually join the Alaska Highway.
In order to avoid using the sea to get from the Lower 48 States to Alaska, the Alaska Highway was built during World War II. 1948 saw its initial public opening.
The three routes that comprise the highway are Alaska Route 2, Yukon Highway 1, and British Columbia Highway 97.
The road was formerly 1,700 miles (2,700 kilometers) long and quite difficult to drive, but it has since been restored and is now only 1,387 miles (2,232 km) long and completely paved.
