What is a corridor? What is an alignment?
A corridor is a broad geographical study area for future transportation projects that follows a general route such as a rail right of way, local road or highway with defined end points. An alignment is a route traveled by a transit line. Within each corridor there may be several alignment options. Some of the corridors in the Triangle region overlap because different lengths or segments are considered along the same path. Some of the alignments may overlap because of the technical feasibility of travel along or over certain rights of way or roads.
