Business routes of Interstate 80

Interstate 80 Business, called the Capital City Freeway in its entirety, is a Business Loop of Interstate 80 through Sacramento. As it is state-maintained, unlike most business routes in California, it is assigned route numbers - part of U.S. Route 50 on its western half (5.64 miles/9.08 km), and unsigned State Route 51 on its eastern half (8.86 miles/14.26 km). The full road is a freeway, and carried Interstate 80 until 1981, when the signage and designation of Interstate 80 was transferred to the Beltline Freeway, previously signed as Interstate 880. At that time, the American Association of State Highway and Transportation Officials (AASHTO) assigned the Interstate 305 designation to the west half, which met Interstate Highway standards. However, the California Department of Transportation (Caltrans) has never signed this number, put it on any road signs, or used it internally. (Note: The Federal Highway Administration lists unsigned I-305 as 8.44 miles (13.58 km),[1] increased from 5.3 miles (8.5 km) in 1999.[2]
