A fire hydrant broke on a brick-lined Georgetown sidewalk Wednesday, flooding the street and forcing authorities to close two blocks to repair the damage.

The water line burst at the base of an 8-inch fire hydrant on the 3300 block of Prospect Street at about 11 a.m. The water pressure knocked loose dozens of sidewalk bricks, which tumbled down the street in the flood. A 10-foot-wide hole opened around the half-cocked green hydrant.
