US 77 is a north-south United States highway. It is unsigned in and around Dallas, Texas. Its historic segment through South Dakota was decommissioned with the advent of Interstate 29 but otherwise the route has been spared the decommissioning that has shortened other US highways. The route has major freeway sections in Oklahoma City including the Broadway Extension (aka Interstate 235) connecting suburban Edmond to downtown Oklahoma City and Shields Boulevard in South Oklahoma City.
