This is the inset map for Columbia from the 1958 official state highway map. Two numbered routes were shown on this map: US 40 and US 63 (both in red). The future route of Interstate 70 was also shown (with the red dotted line). It opened the next year as one of the first Interstate highway segments to be built in the United States.

This map was also much larger than the inset map of Columbia on the 1957 official map.
