Winter weather operations are of special importance for northern tier states and there are some unique opportunities when viewed at the multistate corridor or megaregion scale. For instance, the North/West Passage since 2012 has hosted a winter season operations preparedness webinar and evaluated coordination among the states during major winter events. To support this type of multistate preparation and coordination, the North/West Passage in collaboration with Great Lake Regional Transportation Operations Coalition (GLRTOC) and University of Wisconsin-Madison has aggregated the upper Midwest states’ winter road conditions on a single map. This project extended the multistate winter road condition aggregate map to the remaining four states (Washington, Idaho, Wyoming and Montana) for complete North/West Passage coverage and is available by viewing this example link.
