About the Project

Sound walls were constructed on both sides of the Dulles Connector Road/Route 267, between Chain Bridge Road/Route 123 and Interstate 66 (almost four miles) in Fairfax County. 

The sound walls mitigate noise from Dulles Connector Road traffic and Dulles Metrorail, which was constructed at-grade in the median and on elevated rail flyovers along the Dulles Connector Road. 

Work was completed under two contracts:

1. Ground-mounted sound walls on the Connector Road in each direction from Chain Bridge Road to I-66 (UPC 98232)

Work began in the summer of 2013. The contractor is Lane Construction Corporation.

Sound walls construction on both sides of the Dulles Connector Road/Route 267, between Chain Bridge Road/Route 123 and Interstate 66 (almost four miles) in Fairfax County is complete except for a few minor punch list items.

The contractor also constructed sound barriers spanning the gap between Old Dominion Drive and the beginning of the existing wall on the I-495 southbound (Outer Loop) side.

2. Structure-mounted sound walls parallel to the bridges over Chain Bridge Road, Magarity Road and Pimmit Run (UPC 103668)

The contractor completed the sound walls on both the northbound and southbound sides of all three bridges.

Work began in the fall of 2013. Fort Myer Construction Corporation was the contractor.

Background

The project is constructing 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."
