A road in Knox County washed out by last week’s heavy rains is open again. Appleton selectman Donald Burke say crews finished repairs on the Appleton Ridge Road yesterday and cleared it for travel again. Heavy downpours early Thursday morning damaged more than two dozen roads in Knox County, especially in the towns of Appleton, Union and Washington. At least half-a-dozen of the roads had to be closed for part of the day while town and state crews made emergency repairs. The damage was so extensive on the Appleton Ridge Road, though, that it couldn’t be finished until yesterday.
