Another weekend in May, another regatta on the Schuylkill.

Today and Saturday it is the Stotesbury Cup, billed as the biggest high school regatta in the world.

Of course that means Kelly Drive will be closed between Strawberry Mansion Drive and Fountain Green Drive through 8 p.m. Saturday.

Traffic will be detoured via a marked route to Reservoir Drive.

Meanwhile, streets around Rittenhouse Square will be closed from 3 a.m. until 8 p.m. Saturday for the Rittenhouse Row Spring Festival.

The festival itself is scheduled to run from noon until 5 p.m.

Motorists are advised to avoid the area.
