Motorists will have to be extra careful riding around Door County as the Peninsula Pacers host its annual Peninsula Century Spring Classic on June 17th. Hundreds of cyclists will take part in four different routes ranging between 25 miles and 100 miles. The routes take place primarily in the northern part of the county, with only the 100-mile route going as far south as Institute. The routes are open to normal vehicular traffic with one exception. The Door County Highway Department warns that County Highway F from State Highway 57 to Guy Street in Baileys Harbor will be closed for the event between 5 a.m. and 6 p.m. You will be able to access County F from Park Street.
