Bicycles and dragon boats will mean some road closures this weekend.

Today will even see two sections of the Ben Franklin Parkway closed in preparation for Sunday's TD Bank Philadelphia International Cycling Championship.

The eastbound center lanes from Eakins Oval to 20th Street were scheduled to be blocked off from this morning till the conclusion of the race, about 4 p.m. Sunday.

The westbound center lanes from 20th Street to Eakins Oval were to close at 6:30 p.m. today, also until late Sunday afternoon.

Saturday, both directions of Kelly Drive will be closed between Fountain Green and Strawberry Mansion Drives for the International Dragon Boat Festival. The Schuylkill Expressway (I-76) is one alternative. More event info: www.philadragonboatfestival.com.

Also closed Saturday and Sunday will be the other road along the Schuylkill. All summer long, to promote recreational activities, Martin Luther King Drive closes at 6.a.m. on weekends from Eakins Oval to Falls Bridge. At noon, a stretch reopens from the Eakins Oval (the Art Museum) to the Sweetbriar Cutoff (west of the zoo), but the rest remains closed till 5 p.m.
