Project Objective

To develop a long range master plan for each of the study corridors including early action improvements, safety enhancements, access control policy, corridor preservation objectives and physical upgrades to existing infrastructure. The project will serve as a foundation for future environmental analysis, design and construction efforts.

Linking the corridor study process to support the National Environmental Policy Act (NEPA) process

The Corridor Study will serve as the foundation for future project specific environmental analyses’ embracing the philosophy of "Linking planning and NEPA".

The Corridor Study will be organized in the following manner thereby supporting future environmental planning:

  • Corridor level goals and objectives
  • General travel corridor definition
  • Preliminary screening of alternatives and elimination of unreasonable alternatives
  • Basic description of environmental setting
  • Preliminary identification of environmental impacts and mitigation

Phasing of Alternatives/Plan Forward

Stakeholder outreach is an integral component of linking planning and NEPA. The study process will involve interested state, local, tribal and federal agencies and include Public Review with an opportunity for comment. It will include documentation of relevant decisions and review by the FHWA.
