In western Fairfax County, VA, the Braddock/Pleasant Valley intersection has experienced significant delays for several hours each day. There are numerous constraints to improving the intersection.
Kittelson performed an alternatives analysis of several options and then prepared RFP design plans of a single-lane roundabout to improve safety and capacity of the intersection.
Kittelson performed an extensive alternatives analysis of several traffic control and lane configuration options. A 105-foot ICD roundabout was ultimately selected to minimize the footprint of the project, while solving the operational issues that plague the intersection.
The project was successfully led and constructed through a design-build process by the Virginia Department of Transportation, opening to traffic in spring 2016. Since opening, the 30+ minute delays and mile-long queues have been eliminated, significantly improving travel times and the safety and operational performance of the intersection.
