From at least before 1926, Nebraska Highway 5 used to run down N. 20th Street, jogging east on Ohio Street, and then along 16th. By 1931 this was replaced by N. 30th Street, which was designated as US 73. In 1984 US 73 was replaced by US 75, which maintains its position along N. 30th Street today. Between 1978 and 1980 a new freeway was built from I-480 north to Lake St, called I-580. This status was revoked when the State of Nebraska refused to upgrade the roadway to Interstate specifications, and the roadway is currently called the North Omaha Freeway.
