History
RM 620 was originally designated in 1945 as Farm to Market Road 620 from Round Rock to SH 29, the former designation of US 183 south of Liberty Hill before 1951. In 1946, the road was extended to the Travis County line. Two years later, the road was extended to the former community of Hickmuntown, also called Four Points, at the location of the current intersection with RM 2222. The road was completed in 1952 when it was extended to SH 71, known locally before 1965 as RM 93. The road received its Ranch to Market designation in 1956, and its Urban Road designation in 1995. The SH 45 toll road running along a portion of RM 620 opened in 2006. In 2013, the section from IH-35 to BI 35-L was cancelled and given to the city of Round Rock.
