The Mighty Moraine Multi-Sport Festival is coming to Moraine State Park in Butler County on Sunday, May 20, and with it will come a change to the usual traffic pattern around the park.

From 6 a.m. to 1 p.m. Sunday, traffic on North Shore Drive will flow west-to-east only to ensure the safety of the triathlon participants during the bicycle portion of the event. The one-way pattern will start at West Park Road and end at Mount Union Road. State Department of Conservation and Natural Resources park rangers and traffic control personnel will be on hand to guide motorists while the pattern change is in effect.

Anyone entering the park must enter through the bike rental entrance off West Park Road, and anyone exiting the park must follow the one-way traffic flow toward Mount Union Road.
