Juneau, Alaska

Juneau is unique among the 49 U.S. capitals on mainland North America in that there are no roads connecting the city to the rest of the state nor North America. Honolulu, Hawaii is the only other state capital not connected by road to the rest of North America. The absence of a road network is due to the extremely rugged terrain surrounding the city. This in turn makes Juneau a de facto island city in terms of transportation, since all goods coming in and out must go by plane or boat, in spite of the city’s being on the Alaskan mainland. Downtown Juneau sits at sea level, with tides averaging 16 feet (5 m), below steep mountains about 3,500 to 4,000 feet (1,100 to 1,200 m) high. Atop these mountains is the Juneau Icefield, a large ice mass from which about 30 glaciers flow; two of these, the Mendenhall Glacier and the Lemon Creek Glacier, are visible from the local road system. The Mendenhall glacier has been gradually retreating; its front face is declining in width and height.

The Alaska State Capitol in downtown Juneau was built as the Federal and Territorial Building in 1931. Prior to statehood, it housed federal government offices, the federal courthouse and a post office. It also housed the territorial legislature and many other territorial offices, including that of the governor. Today, Juneau remains the home of the state legislature and the offices of the governor and lieutenant governor. Some other executive branch offices have moved elsewhere in the state.
