||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.
Design was completed in fall 2017 by Halff Associates. A groundbreaking ceremony was held on March 11, 2020. The contractor for the project is Bridges and Roads, LLC. Construction is anticipated to be complete by summer 2023, weather permitting.
