This summer a four-mile stretch of the Dulles Connector Road became the first phase of a larger project in northern Virginia to include ground-mounted sound walls containing SoftSound, a sound absorptive technology. Approximately 277,000 square feet of precast concrete sound wall will be placed on the west side of the roadway between Chain Bridge Road/Route 123 and Interstate 66. The sound walls will mitigate noise from Dulles Connector Road traffic and the new Dulles Metrorail Silver Line extension, which has been constructed at-grade in the median and on elevated rail flyovers along the roadway.
