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.
Status: Construction completion is anticipated for late 2023. For updates, click here or go to RM 620 Roundabout page.
