CAMBRIDGE, Md. (AP) _ A barge that broke loose from its mooring in high winds struck the Choptank River drawbridge, a major route to Maryland's beach resorts, prompting officials to close the bridge temporarily.

One lane of the two-lane span was reopened at 10 p.m. Monday, nearly four hours after The Emerson C. Harrington bridge was closed, No injuries were reported in the mishap.

Ed Owens, a state highway administration maintenance engineer from Dorchester County, said the bridge was closed as a precaution while tug boat crews worked to move the barge. Another barge also broke loose from its mooring, but did not strike the bridge.

There was no apparent damage to the bridge deck, but Owens said it was impossible to check the superstructure and pilings immediately for damage because of wind gusts of more than 40 mph.

The barges are owned by the McLean Contracting Co., one of two construction companies working on a new bridge that will replace the two-lane Harrington Bridge.

Contruction on the new bridge is expected to be completed by the summer of 1987.
