A 20-inch water main broke Monday, flooding the streets in Dupont Circle and temporarily shutting down 17th and P streets in the area.
Seventeenth Street was closed from Q Street south to P Street, and P Street was closed between 16th and 18th streets. All streets have since reopened.
Witnesses told News4 that they saw water shooting up as high as 20 feet of water into the air when the break first happened.
DDOT treated 17th Street and side streets to prevent possible icy conditions.
The water main was installed in 1877.
