RM 620 Overpass at Railroad/Chisholm Trail Project
Location:  RM 620 from IH 35 to Deep Wood Drive
Description: The City of Round Rock, TxDOT, and Williamson County are partnering together on this project on RM 620 to add overpasses at Chisholm Trail and Lake Creek Drive, a roundabout at RM 620 and Chisholm Trail beneath the new overpass, widened lanes, new frontage roads, and will improve bicycle and pedestrian accommodations. The overpasses will separate local traffic from through traffic and allow through traffic to pass over the railroad tracks. 

The project is under construction with bridge work, utility work and roadway improvements being performed at the same time. Construction is anticipated to be complete by late 2023, weather permitting.
