Vandiver Drive Extension

Project Information:

Located in northeast Columbia, the Vandiver Drive Extension consisted of the analysis and design of two multi-lane roundabouts that eliminated the need for a major creek crossing. VISSIM analysis was performed for numerous scenarios to ensure this innovative project would function as intended. The project also included accommodations for bicycle and pedestrian traffic as well as extensive phased construction and traffic control plans. The St. Louis section of the American Society of Civil Engineers selected the Vandiver Drive Extension as its 2010 Project of the Year.
