A sinkhole on I-270 in Gaithersburg has closed the two right lanes on the southbound side of the freeway, according to authorities.
A sinkhole formed in the far right lane of I-270 south prior to the I-370 interchange, state police said in a press release Wednesday night. The sinkhole formed due to a broken 6-foot drainage pipe, according to police.
State Highway Administration [SHA] officials have been notified and are trying to get contractors to perform repairs, according to police.
The SHA posted on Twitter at 8:40 p.m. Wednesday that emergency road work had closed the two right lanes prior to the interchange and that drivers should expect major delays. Drivers are encouraged to use MD 355 as an alternate route.
Charlie Gischlar, an SHA spokesman, told Bethesda Beat that crews would be assessing the repair needs throughout the day on Thursday to make sure no other areas underneath the roads are compromised. He did not have an estimate as to when the lanes would reopen.
“We realize this is one of the busiest roads in the state of Maryland,” he said.
