About the Project
Loudoun County Parkway/Old Ox Road (Route 606) connects two major roads, Route 50 and Route 28 (Sully Road) and is a desirable route for motorists from points west to access Ashburn, Sterling and Herndon. The road is currently congested in both directions during peak hours. This project will address the need to increase capacity on this section of road due to growth in the surrounding area and the resulting increase in traffic congestion.
The project will:
- Reconstruct and widen the existing two-lane rural road to four lanes between Evergreen Mills Road (Route 621) and the Dulles Greenway (Route 267) (a distance of about 5 miles)
- Include provisions for bicyclists and pedestrians.
VDOT awarded the design-build contract to the Shirley/Dewberry team on May 14, 2014 for approximately $77 million. The NTP (Notice to Proceed) was issued on June 19th, 2014. Survey and final design are the first items to occur following the NTP, with construction scheduled to begin in early 2015. Final completion is scheduled for September 2017.
Planning for the widening of the Route 606 corridor between Route 50 and the Dulles Greenway has been ongoing since the early 1990s. The first segment was implemented in 2002-03 with the reconstruction and widening between Route 50 and Evergreen Mills Road.
The project will implement the ‘Interim Condition’ as described in Loudoun County’s Countywide Transportation Plan. This plan calls for Route 606 to be a controlled-access, median-divided urban collector. The ultimate condition as described in the Countywide Transportation Plan calls for a limited-access, median-divided urban arterial. The proposed design implements the interim condition while enabling a future conversion to its ultimate condition.
The Metropolitan Washington Airport Authority (MWAA), Loudoun County and Virginia Department of Transportation (VDOT) are jointly funding the project, which is being developed by VDOT.
