The CoSS were originally developed under VTrans2025 and validated during the VTrans2035 Update process. One new Corridor was recently added by the CTB (Northern Virginia North-South CoSS).
Corridors identified as CoSS demonstrate all of the following characteristics:
As codified by law (S1398, 2009), the CoSS are designated by the CTB. The CTB also is charged with developing criteria for prioritizing the CoSS and conducting studies of the corridors. Recent legislation mandates that localities discuss local segments of the CoSS in comprehensive plan updates.
The major modal components of the twelve Corridors are briefly described in the table below. A full description of each CoSS and its multimodal elements is included in Chapter 3 of the VTrans2035 Report to the Governor and General Assembly.

The Commonwealth of Virginia has identified a set of Corridors of Statewide Significance (CoSS). The Corridors are broadly drawn and include multimodal facilities, including highways, transit services, port facilities, and airports. House Bill 2019, adopted in 2009, requires that the Commonwealth’s long-range transportation plan (VTRANS) set forth an assessment of needs for all CoSS and that all modes of travel be considered. As part of those assessments, the Office of Intermodal Planning and Investment conducts Corridor Master Planning studies. These studies start by unifying the CTB’s vision for each Corridor, the VTrans goals, and local goals. These master plans aim to provide a set of recommendations for the Corridor or Corridor segment. They seek to document existing plans related to the corridor, project future multimodal travel conditions, identify corridor needs based on technical analysis, and present recommendations for how the corridor or corridor segment should be improved in the future.
The designated Corridors differ with respect to their geography, their physical and operational conditions, and their level of past and recent planning. In some cases, meeting the goals of HB 2019 will call for very comprehensive studies; in others, more focused or limited studies to supplement work already performed will be appropriate and sufficient.
Regardless of the level of new effort required, each corridor is addressed according to comparable standards. At a minimum, the CoSS CMPs are designed to provide a multimodal statewide perspective to guide localities in their land use and transportation plans. The CoSS plans are designed to provide sufficient detail to help ensure that local governments can accurately reflect the proper level of detail in local comprehensive plans.
