Project 8.4
Winter Road Condition Map Aggregation

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.
