State Route 83 is a city street running from the Foothill Freeway (State Route 210) in Upland to the Chino Valley Freeway (State Route 71) near the Prado Dam flood control basin.

This route is part of the California Freeway and Expressway System [http://www.leginfo.ca.gov/cgi-bin/displaycode?section=shc&group=00001-01000&file=250-257 CA Codes (shc:250-257)] ] .

Route description

Route 83 is a major north-south arterial serving the cities and communities of Western San Bernardino County. Known as Euclid Avenue for its entire 14-mile (23 km) length, the route begins at its southern terminus at the Chino Valley Freeway (State Route 71) and traverses the communities of Chino, Ontario, and Upland before reaching its northern terminus at the Foothill Freeway (State Route 210). As there is no direct access between Routes 83 and 210, the northern terminus functions as a legislative terminus only - Euclid Avenue, as a city street in Upland and a county road in unincorporated San Bernardino County, continues north into the unincorporated community of San Antonio Heights and provides direct access to Mount Baldy.

North of the Pomona Freeway (State Route 60), Route 83 follows an expanded right of way with six lanes of traffic and a convert|30|ft|m|sing=on wide landscaped median. Through the communities of Ontario, and Upland, the route traverses several designated historic districts, with craftsman homes and civic buildings dating from the late 19th century lining either side of the street. South of the Pomona Freeway (State Route 60), Route 83 assumes the characteristics of a rural highway, narrowing to two lanes while passing through what was traditionally agricultural land.

An interesting and unusual feature of the street occurs at the intersection with the Foothill Freeway (State Route 210) in Upland. During the planning stages for the construction of the Foothill Freeway through the area, Upland residents (in conjunction with the residents of other communities along the route) successfully petitioned the State and local governments to require Caltrans to construct the new freeway 'below grade', i.e. build the road surface of the freeway below the elevation of the surrounding terrain. Furthermore, due to concerns of existing traffic volume, noise, etc. along major thoroughfares, such as Euclid Avenue, many Upland residents who lived along or near Euclid Avenue did not want a fully functional interchange at the junction between the new freeway and the street as it was anticipated that doing so would increase traffic and noise, thereby undermining the aesthetic qualities of the street and negatively affecting the residents' "quality of life". Thus, at the intersection of SR 83 and SR 210, there are no on/offramps or associated improvements like traffic lights - direct access between the highways is not possible. Instead, on both sides of the Euclid Avenue overpass there are two wide landscaped areas that provide a visual (and to a lesser extent, acoustic) buffer between the street and the freeway passing below . The landscaped area also serves to provide continuity with the landscaped segments of the street to the north and south of the intersection.
