McCormick Taylor assisted SEDA-COG in updating the region’s Long-Range Transportation Plan. The Long-Range Transportation Plan identifies transportation needs, goals, projects, and policies for at least a 20-year period, and is fully updated about every five years. It also addresses new federal and state transportation legislation.


The plan establishes the vision and objectives that guide public decisions affecting transportation facilities and services in the SEDA-COG region. It serves as the blueprint for transportation and economic investments that address network deficiencies, safety issues, mobility constraints, accessibility limitations, and unsustainable development.
