Work is currently underway to construct ground-mounted sound barrier walls on the southbound Dulles Connector Road from Chain Bridge Road to I-66 (Phase-1). After this phase has been completed, the contractor will move over to the northbound Connector Road, from I-66 to Chain Bridge Road (Phase-2). This work is being performed in three segments in both phases: Chain Bridge Road to Magarity Road, Magarity Road to Pimmit Run, and Pimmit Run to I-66. Clearing and grubbing shall be confined to those areas required for access to and physical placement of the new sound barrier wall, erosion control devices and temporary safety fence. To the extent possible, all other existing vegetation shall remain.

Phase-1 work on the southbound Connector Road from Chain Bridge Road to Magarity Road has been completed, with the exception of a gap that has been left open at the Magarity Road Bridge in order to provide access for another contractor (Fort Myer Construction Corporation) to construct the foundations for the sound wall parallel to the Magarity Road Bridge. Approximately sixty (60) percent of the required sound wall panels have been installed between Magarity Road and Pimmit Run, with additional panels expected to go up in the next few weeks, weather conditions permitting.

About the Project

This project will construct sound walls on both sides of the Dulles Connector Road/Route 267, between Chain Bridge Road and Interstate 66 (3.96 miles) in Fairfax County. The sound walls will be built to mitigate noise from the Dulles Connector Road traffic and Dulles Metrorail, which is being constructed at-grade in the median and on elevated rail flyovers along the Dulles Connector Road. 

This project will construct sound walls as required by Chapter 874 Virginia Acts of Assembly 2010:

"pursuant to the provisions of the Memorandum of Agreement between the Commonwealth of Virginia Department of Transportation and the Metropolitan Washington Airports Authority, in conjunction with the construction of rail mass transit in the right of way of the Dulles Access/Toll Road Connector (DATRC), sound walls shall be constructed along residential properties from the beginning of the DATRC to Interstate Route 66 with funding from the Commonwealth Transportation Fund."

Construction is scheduled to begin in late summer/early fall 2013 and will be within the existing right of way.
