Closure of Zion Road, from Vantage Drive to Old Missouri Road, has now been extended through September 1, 2021, to allow the contractor to install new sanitary sewer service crossings, new water main and water service crossings, and new storm drain infrastructure in the existing roadway and undercut for new roadway alignment adjacent to the existing roadway. The road will be closed 24 hours a day during this extended period. Traffic will continue to be detoured around the construction area.
