The Virginia Department of Transportation (VDOT) selected a partnership of The Clark Construction Group Inc. and Shirley Contracting Company LLC, to develop, design and build six high-capacity interchanges on Route 28 in Northern Virginia over the next four years.

Improvements to the corridor are vital to the continued economic development of the fast-growing area, which includes Dulles International Airport, AOL Time Warner Headquarters and the Smithsonian’s new Air and Space Museum.

“This agreement will provide a combined commitment of $200 million in improvements to the Route 28 corridor over the next four years,” said VDOT Commissioner Philip Shucet.

It is possible that the project may grow as Route 28 will ultimately be widened from six to eight lanes between Route 7 and Interstate 66 and four interchanges added to convert the road to a limited access highway. The initial six intersection upgrades will be located at the crossroads of Route 606, Route 625 and Sterling Boulevard in Loudoun County. Clark Construction and its heavy/highway construction subsidiary, Shirley Contracting, will perform right of way acquisition, utility relocation and site development, as well as design and construction services.

The project is being built under Virginia’s Public-Private Transportation Act, which allows private entities to propose solutions for designing, building, financing and operating transportation improvements. VDOT will contribute state highway funds and revenue bonds backed by proceeds from the Route 28 Tax District will be utilized to finance the balance of the project. Landowners along Route 28 agreed to pay for improvements to the corridor in 1988, through a special tax district.

Loudoun County, VA, is the second fastest growing county in the nation. More than 100,000 cars a day use the segment of Route 28 just north of the Dulles Toll Road. By 2012, transportation officials estimate that segment will carry 200,000 cars a day.
