A long-running and ever-changing Duluth hotel will tear down the oldest part of its sprawling complex as owners begin work on a new renovation plan for the Endion neighborhood tourist destination.

The Edgewater Resort and Waterpark, 2400 London Road, started demolition work this month on a vacant, two-story wing that was constructed in 1965 and served as the Edgewater Motel for decades. The Edgewater Resort and its adjacent waterpark will remain open during the project.
