U.S. Route 101 Business is a business loopofU.S. Route 101 that runs along Wildwood AvenueinRio DellinHumboldt County, California. Its southernmost section between US 101 near Scotia to the north end of the Eel River Bridge is legally defined as an unsigned state highway, State Route 283 (SR 283). The route was defined in 1970 as a transfer from a realigned US 101 after a freeway bypass was built.
State Route 283 spurs out of US 101 near Scotia, south of Rio Dell, while carrying US 101 Business from that intersection to the Eel River Bridge. After crossing the bridge, SR 283 ends and US 101 Business continues north through the center of Rio Dell to US 101 in the northern part of the city.
SR 283 includes the length of the Eel River Bridge, keeping its maintenance to Caltrans. The bridge itself was built in 1941, when U.S. Route 101 ran through what was then known as Eagle Prairie. In 1977, the bridge was renamed the Albert Stanwood Murphy Memorial Bridge, in honor of the Pacific Lumber Company president who assisted the Save the Redwoods League. In 1990, the bridge was given a second name, the Eagle Prairie Bridge, in honor of the 50th anniversary of the bridge's construction and the 25th anniversary of Rio Dell's incorporation.[3]
SR 283 is not part of the National Highway System,[4] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[5]
Except where prefixed with a letter, postmiles were measured on the road as it was when the route was established, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see California postmile § Official postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Humboldt County.
