SHARPSBURG, Md. (AP) — The National Park Services says it's closing the landmark Burnside Bridge at the Antietam National Battlefield for major repairs that will continue at least into next spring.

Park managers said Thursday they will close the bridge Friday for the $1.7 million preservation project.

Problems surfaced in January 2014 when some stones from the bridge fell into Antietam Creek. Temporary repairs were made but the park service says its investigation revealed substantial deterioration and structural instability.

The bridge was built in 1836 and is among the best-known structures at Antietam. It served a key role in the 1862 Battle of Antietam when a small number of Confederates defending the critical crossing held off Union forces commanded by Maj. Gen. Ambrose Burnside for several hours.
