Route 28 Corridor Improvements PPTA

In 2002, the Shirley Design-Build Team was awarded the first Public-Private Transportation Act (PPTA) project to be implemented in the Northern Virginia area by the Virginia Department of Transportation (VDOT). The Project scope included the widening of Route 28 from six to eight-lanes along 14 miles of this heavily traveled roadway between I-66 and Route 7; ten grade-separated interchanges; and numerous secondary road improvements. Shirley and Lead designer Dewberry were responsible for all design and engineering, permitting, right-of-way acquisition of residential and commercial properties, utility relocations, construction, maintenance of traffic, quality assurance and quality control, and coordination of public involvement for all project work.

The initially funded scope included the design and construction of six of the ten grade-separated interchanges. The Team completed all of these interchanges ahead of schedule. Due in large part to the success of our Team’s work, VDOT issued a change order for the Design-Build construction of the final four of the ten interchanges in November of 2006. In addition to the ten interchanges, the Team was responsible for Design-Build completion of numerous parallel secondary roads including the widening of Centreville Road; a new four-lane section of Loudoun County Parkway; a new four-lane section of Davis Drive, two different new sections of Pacific Boulevard, and a new four-lane section of Atlantic Boulevard including a new bridge over the W&OD Trail.

The Route 28 project received many accolades and awards, including the 2004 Tower of Dulles Award, presented by the Committee for Dulles in recognition of distinguished service to the Washington Dulles International Airport.
