WASHINGTON COUNTY -- A 12-foot sinkhole closed one lane of traffic Friday in the westbound lanes of Interstate 70 and caused big backups.
The sinkhole opened before 11 a.m. in the median adjacent to the road's shoulder east of the U.S. 40 interchange, Maryland State Police said.
Police closed the left lane of westbound I-70 for more than four hours while State Highway Administration (SHA) workers filled the sinkhole, causing traffic to back up as many as nine miles.
The road was reopened about 3 p.m., according to an SHA press release.
Robert Fisher, district engineer for the SHA, said Friday afternoon that road crews would repair the sinkhole by filling it with flowable backfill.
