Release: VDOT

The Virginia Department of Transportation (VDOT) will host a “pardon our dust” meeting on a project to reconstruct the Interstate 66 and Route 15 (James Madison Highway) interchange (Exit 40) in Prince William County. Meet the project team and learn more about construction schedule and traffic impacts.

The public can stop by between 6:30 and 8 p.m. Wednesday at Ronald W. Reagan Middle School, 15801 Tanning House Place, Haymarket. A formal presentation will begin at 7 p.m.

The Lane Construction Corp. and its lead designer, Rinker Design Associates, were awarded the design-build contract for the interchange. The project is expected to be completed in the fall of 2017.

VDOT will begin work this summer to ease congestion, enhance public safety and accommodate forecasted increases in traffic by replacing the existing diamond interchange with Virginia’s third diverging diamond interchange (DDI).

A DDI is designed to handle more than twice the left-turning volumes of a conventional diamond interchange. The DDI also would improve safety by significantly reducing the number of locations where vehicles could collide.

Other improvements will include:

• Two new bridges to carry U.S. 15 over I-66 with two crossover intersections;
• Ramp improvements (including a spur ramp to ease traffic flow from westbound I-66 to northbound U.S. 15 to westbound Heathcote Boulevard);
• Improvements on U.S. 15 from just north of the railroad tracks to just south of Heathcote Boulevard;
• Improvements to the intersections on U.S. 15 at Heathcote Boulevard and Route 55; and
• A 10-foot-wide shared-use path on the west side of U.S. 15 for pedestrians and bicyclists.
