Former Business Route

1963 map of Sacramento, California — U.S. 40 Business assigned to West Capitol Avenue – 1963 Gousha map of Sacramento. This route may have been the predecessor of the first Sacramento business loop for Interstate 80.

1976 Map of Sacramento, California — Old 1970s AAA maps of Sacramento displayed Business Loop I-80 along W Capitol Avenue.

A possible earlier business route from Interstate 80 in Sacramento appeared on a 1963 Gousha map of Sacramento as U.S. 40 Business along West Capitol Avenue [see map at right]. The route parallel the West Sacramento Freeway (U.S. 40/99W) to the north from what is now Exit 81 east to the Tower Bridge. This includes a portion that no longer exists east of 5th Street.

According to Jerry Mullady, the route was later designated as Business Spur I-80. If the route was signed, it was not posted when the Business Loop 80 Freeway was commissioned in 1982.
