Several roads and trails are closed in Wisconsin's Chequamegon-Nicolet National Forest as “major” construction gets underway, according to the U.S. Department of Agriculture.

The construction comes after flash flooding from storms in 2016 damaged trails and roads in the national forest. It’s expected to last through spring 2020, according to a USDA spokesperson.

The project includes replacing bridges and culverts, repairing roads and trails and resurfacing roads.

Several portions of forest roads will be closed throughout the construction. Those traveling in the areas between Mellen, Drummond and Clam Lake may experience delays and detours because of construction, according to the USDA.

The July 2016 storm brought 9-13 inches of rain, causing $15 million in damages and closed eight roads in the forest, according to a press release from the USDA.

Updates on the construction are available on the USFS’ website and on its social media.
