This is the inset map for Jefferson City from the 1957 official state highway map. Three numbered routes were shown on this map: US 50, US 54, and US 63 (in red). Also shown was Alternate US 54, paralleling US 54 (in red as well). US 50 and US 63 were concurrent through much of Jefferson City while US 54 and US 63 were concurrent from Jefferson City to their junction just across the Missouri River. Those concurrencies remain today, even though the routes have shifted over time.
