 Completed in 1973, the Sitka Harbor Bridge in Sitka, Alaska, is the first cable-stayed highway bridge in the United States. The cable-stayed welded steel box girder design was selected to make the structure as visually unobstructive as possible from Sitka and Castle Hill, the site of Baranof Castle, from which the Russians governed Alaska prior to 1867, when it became a U.S. territory.
