WAUNAKEE, Wis. -- Dane County officials on Monday kicked off the beginning of a reconstruction project aimed at reducing congestion on a busy highway along the northern shore of Lake Mendota.

The project will see County Highway M expanded from two lanes to four between Oncken Road near Governor Nelson State Park to Willow Road, with the goal of increasing capacity and safety. The existing four-lane portion of Highway M from Willow Road to State Highway 113, meanwhile, will be resurfaced.
