Studies

What's Being Done?

The Tier 1 EIS is studying potential multimodal improvements that can address existing and future transportation needs in the Interstate 66 corridor from U.S. Route 15 in Prince William County to Interstate 495 in Fairfax County. 

The study area encompasses areas both north and south of I-66. 

The EIS is being developed as a Tier 1 document. 

A Tier 1 EIS differs from a traditional EIS in that it focuses on broad issues such as:

• Purpose and need
• Travel modes (bus, carpool, rail transit, car, etc.)
• Technology choices
• The general location of proposed improvements

This Tier 1 Environmental Impact Statement (EIS) is being developed by the Virginia Department of Transportation, the Federal Highway Administration and the Virginia Department of Rail and Public Transportation.

Throughout the study, residents can offer suggestions and voice concerns. 

To gather input for a "purpose and need statement" for this study, public meetings were held in June 2011, and January and February of 2012. March 2013 public hearings focused on the Tier 1 Draft EIS, which entails:

• Extensive traffic forecasting
• Analysis of how  transportation modes work in combination with others 
• Evaluations of possible impacts on the natural and human environments
