Parking Lot Repairs

Williamson County will be doing repairs and improvements to the parking lots in the Southwest Williamson County Regional Park starting June 7, 2021. Work includes crack filling, fog sealing and striping the parking lots on a rotating basis over two weeks from June 7 to 26. Make-up days due to weather are scheduled for June 28 to July 2, 2021, if necessary.

Southwest Williamson County Regional Park will not close during this time period, however various parking lots at any given time will be closed for up to 72 hours to complete the necessary work.  The contractor will try and minimize impacts; however, visitors may need to park in nearby lots and walk or bike to their event. For a schedule that confirms which parking lots will be closed on which days, click here (schedule).
