[Editor’s note: Check out the snowy road conditions in Colorado with this mashup that includes current road open/close as well as surface status (icy, blowing snow, etc). One of the best I’ve seen. Traffic cameras are overlayed with auto clustering of nearby markers. Includes a searchable list and good legend below the map. Hard to scroll wheal up and down on the page due to the map and list view. And resizing makes it hard to get the legend on the same viewable window area as the map. Thanks Curt!]
