Corridor Master Plan Project Vision

The Northern Virginia North-South CoSS will be an integrated, multimodal network of transportation facilities that connect major centers of activity within and through the Commonwealth and promote the movement of people and goods essential to the economic prosperity of the state.

Commonwealth Transportation Board Definition

The corridor is defined as the area generally east and west of:  Route 234 (Dumfries Road) between I-95 and I-66; the CTB approved location of the Tri-County Parkway between I-66 and Route 50; connections to the Dulles Greenway and Route 7 along Northstar Boulevard and Route 659 (Belmont Ridge Road).

Commonwealth Transportation Board Involvement

Open House Meetings Information

On December 18th and 19th 2012, as well as on January 9th, 2013, the study team shared evaluation results of the transportation alternatives and preliminary recommendations. The alternatives will address access to major activity areas, transit service and non-motorized modes of travel, environmental considerations, and transportation funding and investments within the corridor. Learn more about these alternatives by reviewing the meeting boards from both sets of meetings below. The second set of informational boards expands on initial model results, summarizes public comments received as of January 2nd, and provides recommendations for a refined third alternative.
