U.S. Route 50 has reopened after a two-foot sinkhole shut down eastbound traffic in Annapolis Wednesday, the Maryland State Highway Administration said.

The sinkhole, which closed traffic during Wednesday's evening rush hour, was located across the right lane and second lane at MD Route 665. A team of SHA engineers, a geologist and shop technicians investigated the hole and found that a drainage pipe under the highway had deteriorated and collapsed, causing what officials called a "pavement void."

The hole, which was several feet deep, was filled overnight with stone and patched with concrete on the road surface, SHA said. More permanent repairs are in the works.

A driver discovered the sinkhole around 5 p.m., and all three eastbound lanes were closed, causing significant traffic backups during rush hour. Officials said at around 3 a.m. that the highway had reopened.
