Safety concerns have prompted the county to close a sidewalk along a bridge over Four Mile Run connecting Arlington and Alexandria.

The western sidewalk of the bridge connecting S. Arlington Ridge Road with Mount Vernon Avenue is now closed indefinitely, the county announced last week.

Officials say a recent inspection revealed “beam deterioration” on one of the supports under the bridge’s western sidewalk. The structure was built back in 1956.

The county now plans to use “signage and barricades” to direct people to the other side of the bridge. A Metrobus stop serving the 10A, 10E, 23A and 23B routes and the entry to the Four Mile Run Park and the Four Mile Run Trail sit just before the north end of the bridge on the east side at S. Glebe Road.

Another Metrobus stop sits at the northwest corner of Arlington Ridge and Glebe Road, serving the 10A and 10E routes.

County engineers plan to “monitor conditions and look at eventual replacement options,” but have no timetable for the sidewalk to reopen.

The county closed sidewalks along another nearby bridge at W. Glebe Road over Four Mile Run due to similar concerns back in November.
