An 8-inch water main ruptured Tuesday at Third and Arch Streets, flooding some nearby basements and closing streets in the area. The break happened around 10 a.m.

Laura Copeland, a Philadelphia Water Department spokesperson, said crews were working to shut off the flow.

Water flooded the basements of at least three nearby businesses, and Copeland said Water Department claims inspectors would visit the sites.

Third between Market Street and Arch was closed, as was Arch between Second Street and Third. It was not immediately known when the streets would reopen.
