I-66/Route 29/Linton Hall Interchange Improvements

The Virginia Department of Transportation (VDOT) awarded Shirley Contracting Company, LLC the I-66/Route 29/Linton Hall Interchange Improvements project in Gainesville, Virginia. The Design-Bid-Build project was the final phase of the Gainesville/I-66 Improvements project.

The project included a pair of overpasses: one carrying Route 29 over the Norfolk Southern Railroad, and one carrying Linton Hall Road and John Marshall Highway over the railroad and Route 29. To further improve traffic flow, crews also widened Route 29 to 6-lanes and eliminated driveway entrances and two traffic signals between I-66 and Virginia Oaks Drive. The new, grade-separated interchange at Route 29/Linton Hall Road created a limited-access facility on Route 29 between Virginia Oaks Drive and Heathcote Boulevard.

The phased construction also included construction and removal of several traffic detours during construction; over one million cubic yards of earthwork operations including 105,000 cubic yards of excavation and 947,000 cubic yards of embankment; ground improvements; storm water and water utility installation and relocation(s); approximately 59,100 tons of aggregate base; 123,500 tons of asphalt; signal installation/modifications; roadway lighting, TMS and signage; concrete crash walls; 10 MSE retaining walls consisting of approximately 288,000 SF of precast concrete panels and wire mesh facing; four new bridges; and traffic control. Roadway elements included installing roadway lighting, guardrail, pedestrian sidewalks, and traffic.
