SOUTH PORTLAND — It’s all about swimming, cycling and running Sunday during the 4th annual Tri for a Cure, which might make driving in the area difficult.

With nearly 1,000 race participants and thousands more spectators, roads in portions of South Portland, Cape Elizabeth and Scarborough will likely see increased traffic flow and congestion.

Street closures are expected in the area of Southern Maine Community College, as well as delays on Broadway, Ocean Street, Cottage Road and Willard Square. Fort Road, Benjamin Picket and Surfsite will be closed from 7 a.m. to 1 p.m. Northbound traffic on Preble Street will be diverted up Elsmere Avenue during the race, which starts at 10 a.m. Shore Road in Cape Elizabeth will be closed to northbound traffic from 10 a.m. to 1 p.m.
