The Roadways in Zone 1 are Declared Frozen as of 12/6/14 at 12:01 AM
Prior to this year the earliest we've ever declared the roads frozen is December 5th with the average beginning date of December 22nd.
Being this early brings up an issue that we've not had to deal with before. The issue is that if we get a warming period where the roads begin to thaw between now and when the roadways are typically frozen then we'll have to suspend the frozen road period.
Hopefully winter is here to stay and we don't have a disruption but I wanted to bring it to everyone's attention that this is a real possibility given this unusual early winter. So please stay alerted to future emails and also monitor our website regularly.
We'll be updating the web pages and phone recording throughout the day.
Be aware that the boundaries between the zones recently changed. The new boundaries are as follows:
- Zone 1: Extends from the Minnesota border, Lake Superior, and the Michigan border south to and including US Highway 8.
- Zone 2: Extends from the southern limit of Zone 1 to and including a line defined by US Highway 10, east on State Highway 73, east on State Highway 54, north on State Highway 22/110, east on State Highway 22 east to Lake Michigan east of Oconto (including Highways 10, 22, 54, 73, and 110).
- Zone 3: Extends from the southern limit of Zone 2 to and including a line defined by US Highway 151, east on US Highway 10 to Lake Michigan (including Highways 10 and 151).
- Zone 4: Extends from the southern limit of Zone 3 to and including a line defined by I-39/90 starting at the Illinois border, east on I-43, north on State Highway 164, east on State Highway 167 east to Lake Michigan (including Highways 39/90, 43, 164, and 167).
- Zone 5: Extends from the southern limit of Zone 4 to the Illinois border and Lake Michigan.
