 We Work with Local Stakeholders to Minimize Impacts

The I-66 Project team engaged in extensive design phase coordination with the Manassas National Battlefield Park, the National Park Service and other Park stakeholders to minimize any potential visual impacts of the project to multiple historical locations and vantage points within the national park property.  Through this coordination effort, several significant design changes were implemented, including adjustments to the location of two proposed Express Lane access ramps.  Design coordination efforts concluded with concurrence from the Manassas National Battlefield Park in a finding of no significant impact for the Project’s design plans.

The Project team also developed, in coordination with the Park, an historically sensitive aesthetic plan for adjacent project areas, to include plantings and wall finishing in keeping with the historical nature of this national landmark.   Coordination with the Park continues through construction phase as work to transform the I-66 corridor in the area adjacent to the National Park advances.
