Tysons Corner Neighborhood Traffic Impact Study, Phase II (FCDOT)
McLean CBC Intersections Being Studied
The Tysons Corner Neighborhood Traffic Impact Study analyzed intersections surrounding the Tysons Urban Center to determine the effect of the adopted Tysons Comprehensive Plan on those intersections. The goals of the study are to estimate 2030 volumes at the intersections, determine intersections that are projected to potentially require improvements, and to propose mitigation measures.
Phase I of the study, which was completed in August 2010, analyzed 19 intersections; and, Phase II, which is anticipated to be completed in 2016, includes an additional 10 intersections, for a total of 29 intersections. The study used the latest land use information based on rezoning approvals and applications associated with the Tysons Consolidated Traffic Impact Analyses (CTIA); and, the detailed CTIA travel demand model to assess intersections and identify mitigation measures.
Of the 29 intersections studied, eight intersections are located within the McLean CBC:
- Dolley Madison Blvd/Lewinsville Road/Great Falls Street
- Dolley Madison Blvd/Old Dominion Drive
- Lewinsville Road/Balls Hill Road
- Great Falls Street/Chain Bridge Road
- Dolley Madison Blvd/Chain Bridge Road
- Dolley Madison Blvd/Churchill Road
- Old Dominion Drive/Chain Bridge Road
- Chain Bridge Road/Westmoreland Street
When complete, the Phase II report will be referred to in the Comprehensive Plan, and as developments come on-line near these intersections if dedicated right-of-ways are needed to implement the traffic impact study’s recommendations. The key differences between Phases I and II, involve the land use assumptions and the modeling methodologies.
