Rt 127 will be closed at 6:30am and won't open back up until approx 9:00am

Rt 703 on the North Side of the Lake will be closed to West Bound Traffic and will only have traffic flowing East in the East Bound Lane.  Residents and spectators are encouraged to utilize Rt 29 in lieu of 703.  

IMPORTANT NOTE: - Even though traffic is being managed by law enforcement and emergency personnel, participants should be aware of potential traffic conflicts at all times.  All lanes that the race is being run in will be closed for runners, but caution should always be taken.
