Why Corridor Planning?

Corridor planning can
prioritize which
transportation projects
need to proceed to the
programming and
development stage, and to
explore economical
alternatives to highway
construction. The purpose
of corridor planning is to
comprehensively address
future transportation
needs, and to recommend
a package of
improvements and
management strategies for
the transportation system
within a corridor.


What is Corridor Planning?

Corridor planning is a process that is collaborative with local governments and includes extensive public participation opportunities.

A corridor may be divided into logical, manageable smaller areas for the purpose of corridor planning. The process looks at the existing transportation system within the corridor and how the system could be changed to meet long-term needs. The process includes discussion of existing and projected travel patterns and social, environmental, and economic issues within the corridor. It includes discussion of infrastructure improvements in combination with wise land use and system-management actions.

A corridor plan is a document that defines a comprehensive package of recommendations for managing and improving the transportation system (which includes transportation facilities and services) within and along a specific corridor, based upon a 20-year planning horizon. Recommendations may include any reasonable and effective mix of strategies and improvements for many modes.

What is the purpose of corridor planning?


Corridor Planning accomplishes the following:
  • Promotes the safe and efficient movement of people, goods, and services.

  • Initiates an intergovernmental cooperative planning process to promote community and state based transportation decisions.

  • Provides opportunities for public, local government, and agency participation early on and throughout the process, and promotes active participation in potential corridor solutions, including the development of context sensitive solutions; meets objectives by comprehensively addressing transportation issues, and evaluating a full range of multimodal solutions for increased mobility.

  • Saves money by identifying long-range right-of-way needs by anticipating potential problems resulting from growth before solutions become too expensive.

  • Fills the gap between the statewide modal plans for highways, public transportation, rail, aeronautics, and bicycle/pedestrian, and the project selection process.

  • Furnishes a link between land-use planning and transportation planning.

  • Determines the extent of the social, economic, and environmental issues within the corridor and analyzes potential alternatives at an appropriate and economical level of detail.

  • Facilitates resolution of major issues (i.e., public opinion, cost, environmental constraints) before specific project programming and development begin.

  • Protects transportation investments by exploring alternate means to accommodate transportation needs, with and without capital-intensive improvements.

  • Provides an opportunity to direct future development, and minimize environmental, social, and economic impacts.
