The District 3 I-94 and District 6 I-35 Alternate Route Signing Final Report chronicles the process of developing an alternate route system for interstate corridors. Major delays and roadway closures occur along the Interstate system as various incidents occur on the roadway. These incidents require cooperation between MnDOT, Minnesota State Patrol, and local first responders to respond to the scene and manage Interstate traffic until the corridor can be opened. These alternate routes provide guidance to first responders and MnDOT staff should an incident occur. Alternate route systems were developed for the I-94 corridor through District 3 and the I-35 corridor through District 6. The process used in developing these alternate routes is transferable to other corridors throughout the State. This research project includes the route development process and the development of two final deliverables for use by MnDOT Districts and local stakeholders. The process of developing alternate routes required field review exercises and input from the project's Technical Advisory Panel and other local stakeholders. The project resulted in the development of an Alternate Route Operations Guide and a Signing Plan. The Alternate Route Operations Guide is intended to provide a tool for first responders during an incident by providing suggested routes and temporary traffic control with an outline of the necessary actions for implementation. Suggested static signing locations are provided within the Signing Plans developed with the project.
