101. This relinquished segment south of I-880 within San Jose is legally no longer a state highway, but the state's Streets and Highways Code mandates that the City of San Jose is still required to maintain "signs directing motorists to the continuation of Route 82" and "ensure the continuity of traffic flow" on this segment. Signs along US 101, I-280, and SR 87 where these relinquished segments intersect still have SR 82 shields. Though as of 2017, certain signs with SR 82 shields have been removed along US 101 near Blossom Hill Road and Capitol Expressway. SR 82 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 Originally a segment of US 101 (and before that, the historic El Camino Real), the highway became completely inadequate for the needs of traffic with the rapid growth of the San Francisco Bay Area after World War II, including urbanization of the towns along its path. The Bayshore Highway to the east was originally built as "Bypass (BYP) US 101" and was upgraded to a freeway in 1937. With this upgrade, the original US 101 route was transferred to the Bayshore Freeway, and El Camino Real became US 101 BYP, but in response to protests, the switch in designations was reversed two years later, in 1939, and the Bayshore Freeway remained US 101 BYP until 1964. In 1964, US 101 was moved again onto the Bayshore Freeway, and its former alignment on El Camino Real became SR 82. It was defined as two portions: From Route (US) 101 near Ford Road south of San Jose to Route (US) 101 in San Francisco (which today corresponds to the Alemany Maze), and from Route (US) 101 near Alemany Boulevard to Route (SR) 87 (current unconstructed SR 230) in San Francisco. In 1968, the portions from I-280 (at current SR 82) to US 101 and from SR 101 to SR 87 were transferred to I-280. SR 87 was then deleted north of SR 237 in 1980, and is only constructed south of US 101, and SR 82 today is designated as part of El Camino Real. In 2013, SR 82 was relinquished south of I-880 through San Jose. However, the state's Streets and Highways Code states that the City of San Jose is still required to "ensure
