A large number of bicyclists are expected to be traveling through Sturgeon Bay Sunday as part of the Door County Triathlon headquartered near Egg Harbor. Motorists will see a high concentration of bike-riders between 9 and 11AM on 3rd Avenue downtown and along Memorial Drive as they head to Cove Road, Canal Road and Buffalo Ridge. After traveling into the Institute area, the bicyclists will turn around and retrace their route back into Sturgeon Bay. Between 10AM and 1PM, drivers could encounter bicyclists along Memorial Drive and 18th Avenue as they head in either direction. Sturgeon Bay Police personnel will be joined by community service officers to provide traffic control. Volunteers will also be located along the route to ensure that bikes and automobiles share the road.
