"Liberty-Mounds"
The signs on US Route 75 pointing in the direction of Liberty east of the highway show the name as “Liberty-Mounds”. The Liberty town name was taken from the nearby Liberty School District. Given the district's proximity to Mounds, Oklahoma on the west side of US-75, a former school superintendent referred to the district as “Liberty-Mounds” to distinguish it from another Liberty school district near Morris in Okmulgee County. So the highway signs reference the school, although both the town and the school district are actually named Liberty.
