Drivers are reminded that there will be road closures in the beach area Sunday morning during the Fairfield Half Marathon.

The race starts at 8:15 a.m. at Jennings Beach, but shuttles for runners will begin transporting runners to the starting line at 6:30 a.m. from the downtown railroad station. A post-race party starts at the beach at 9:45 a.m.

“Roads will be closed for short durations while runners pass from the start out to the turn around, and back into the beach area,” Deputy Police Chief Chris Lyddy said.

He said delays can last up to 45 minutes, particularly as the largest numbers of runners return to the beach area.

As the volume of runners permits, vehicular traffic will be allowed to cross the route.

Police plan to issue the following advisory Sunday:

1. Residents south of the Old Post Road, between Reef and Beach roads, should expect traffic delays between 8:15 and 8:35 a.m., and again when the runners return between 9:15 and 10:45 a.m.

2. Residents south of Oldfield Road, between Reef and Sasco Hill roads, should expect delays between 8:20 and 8:45 a.m., and again when runners return between 9:15 and 10:30 a.m.

3. Residents on and south of Pequot Avenue and Westway Road, as well as Oxford Road, should expect delays between 8:25 and 9:45 a.m.
