The western segment of RM 620 between SH 71 and RM 2769 is designated a scenic roadway by the City of Austin.[3]
RM 620 was originally designated on July 9, 1945 as Farm to Market Road 620 (FM 620) from Round Rock to SH 29,[1] the former designation of US 183 south of Liberty Hill until May 23, 1951.[4][5] On May 13, 1946, the road was extended to the Travis County line.[1] On August 26, 1948, the road was extended to the former community of Hickmuntown,[1] also called Four Points, at the location of the current intersection with RM 2222.[6] The road was completed on December 17, 1952 when it was extended to SH 71,[1] known locally before August 31, 1965 as RM 93 (but was signed as SH 71 since October 31, 1955).[7] The road received its Ranch to Market designation on October 1, 1956.[1] The SH 45 toll road running along a portion of RM 620 opened in 2006.[8] On February 28, 2013, the section from I-35 to Bus. I-35 was cancelled and given to the city of Round Rock, along with part of BI 35-L itself. On June 27, 2019, RM Spur 620 was designated from RM 620 northeast to RM 2222 along the westernmost portion of PASS 1402 (Arterial 8);[9] however, RM Spur 620 has not been constructed yet.[10]
On June 27, 1995 the internal designation of the route was changed to Urban Road 620 (UR 620); the designation reverted to RM 620 with the elimination of the Urban Road system on November 15, 2018.[11][12]
