Braddock Road and Pleasant Valley Road
|Roundabout in western Fairfax County|
Project at a Glance
Construction work started in June 2015. Traffic control signs and perimeter controls have been installed. Installation of drainage structures are ongoing as well as utility relocation work. Four variable message boards are onsite and activated as necessary. Placement of base asphalt has started at the intersection with final surface paving to be completed by May 2016.
About the Project
This design/build project will construct a roundabout at the intersection of Braddock Road (Route 620) and Pleasant Valley Road (Route 609) in Fairfax County.
As of 2012, about 7500 vehicles per day travelled this section of Braddock Road and about 8500 travelled along Pleasant Valley Road.
The roundabout will provide additional capacity for forecasted traffic volumes and improve safety by eliminating the potential for turn/angle crashes at the intersection. It will also enhance pedestrian access for residents in the area.
The new roundabout includes crosswalks and curb ramps for pedestrians, landscaping and lighting. The sidewalk will be tied into the existing trail along the east side of Pleasant Valley Road south of the intersection.
The intersection is currently a four-way stop, with a single lane in each direction.
During weekday peak hours, the intersection experiences substantial congestion, operating at full capacity with extensive backups on Braddock Road eastbound in the mornings and westbound in the evenings. The congestion results in severe delays, causing the intersection to operate at a service level of “F” (failing) during peak periods.
Designs for improvements here must take into account parkland, commercial property, an Agricultural-Forestal District, wetlands, rare habitats, and significant overhead utility poles. Taking these constraints into consideration, VDOT, in cooperation with Fairfax County, prepared preliminary plans.
There will be no lane closures during rush hours. Drivers can expect occasional lane closures with flagging on weekdays 9:30 a.m. to 3 p.m. (Fridays removed by 2 p.m.) and nighttime lane on closures weekdays and during weekends, as needed.
