About the Project

Sound walls are being 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 will mitigate noise from Dulles Connector Road traffic and Dulles Metrorail, which has been constructed at-grade in the median and on elevated rail flyovers along the Dulles Connector Road. 

Work is being 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 June 14, 2013. The contractor is Lane Construction Corporation.

Crews are working on the southbound side first, then northbound. The contractor will also construct sound barriers spanning the gap between Old Dominion Drive and the beginning of the existing wall on the I-495 southbound (outer loop) side. Work on this portion is expected to begin in December 2014/January 2015. Currently the contractor is working between Pimmit Run & I-66 on the southbound side of the Dulles Connector Road. Preparations are underway to start work on the northbound side from I-66 towards Chain Bridge Road.

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

Work began on Oct. 28, 2013. Fort Myer Construction Corporation is the contractor. 

The contractor completed the foundation work on both the northbound and southbound sides of all three bridges on Chain Bridge Road, Magarity Road & Pimmit Run. Truss assembly is underway at Pimmit Run and Magarity Road on the northbound side of the Dulles Connector Road.

Both contracts have a fixed completion date of May 29, 2015.

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."

Traffic Impacts

Daytime shoulder closures remain in effect from Magarity Road to Pimmit Run, with minimal disruption to traffic.
