Route 7 / Rivercreek Parkway Interchange


Kettler Inc.


Dewberry Engineers Inc.






To improve access to their planned development at the Villages of Leesburg, Kettler proffered
a grade separated interchange at the intersection of Route 7 and Rivercreek
Parkway. In 2004 Kettler awarded Dewberry Engineers Inc. contract to design a
spread diamond interchange, including a bridge carrying Rivercreek Parkway over
Route 7, ramp connections between Rivercreek Parkway and Route 7, and 3,400 linear
feet of four-lane roadway for Rivercreek Parkway and Crosstrail Boulevard. The design
required close coordination with VDOT, the Town of Leesburg, and Loudoun
County who all had approval authority over the plans. This included numerous
reviews by the Town of Leesburg Board of Architectural Review who added numerous
aesthetic elements to the project including ashlar finish and staining of sound barriers
and retaining walls, aesthetic panels to disguise the bridge pier, detailed architectural
bridge railings and light poles, and extensive landscaping plans.

In 2005, Kettler contracted with Shirley Contracting Company, LLC to complete
constructability reviews of the Dewberry plans and coordinate extensive utility relocations
including a 10” waterline, a 24” Town of Leesburg effluent line, 8” sanitary sewer, 30”
Dominion Gas transmission line, 30” Columbia Gas transmission line, 12” and 24”
Washington Gas lines, and overhead electric, telephone, and cable TV lines. In our
utility coordination efforts, it is always our first priority to identify design options to
eliminate the need to relocate utilities. In lieu of relocating the 30” gas transmission
lines, the Design-Build Team provided a solution to include a bridge over the
Dominion Gas and Columbia Gas easements and Shirley coordinated with the gas
companies to eliminate the transmission line relocations resulting in a savings of over $4
million to the utility relocation budget.

Kettler ultimately contracted with Shirley to construct the Route 7/Rivercreek
Interchange, which was completed on budget and in accordance with the approved
project schedule.
