WASHINGTON (AP) — The D.C. Water utility says a sinkhole that has closed a major intersection in downtown Washington will require complex repairs.
Workers are trying to determine what caused underground concrete to fall 15 feet into a sewer line below. An investigator on Tuesday found concrete had collapsed a 54-inch brick sewer line.
D.C. Water says the sewer line dates to 1897 and has utilities and old trolley tracks running above it.
The busy intersection has been closed since Tuesday. Traffic is being diverted from 14th Street northwest between Pennsylvania and New York avenues and F Street northwest between 13th and 15th streets.
Officials say the road collapsed at the intersection Tuesday afternoon leaving a 15-foot hole.
