) in the background. It is a western alternate route of
U.S. Route 101 between
Eureka and
Arcata, routed via the three bridges over
Humboldt Bay and
Tuluwat Island and Woodley Islands, rather than motorists having to circumvent the entire northern section of the bay (known as Arcata Bay) to the road connecting the Arcata area to the Samoa Peninsula. In literature and locally, the portion of the road crossing Humboldt Bay (on three separate bridges) is known collectively as the "Samoa Bridge", the bridge is considered a freeway. Highway 255 provides direct access to industrial operations on the Samoa Peninsula and the communities of
Samoa,
Fairhaven, and
Manila, all of which are located on the Samoa Peninsula, with the entire combined area located within Greater Eureka. SR 255 is part of the
National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the
Federal Highway Administration. ==History==
