PITTSBURGH (KDKA) — The Tenth Street Bypass will have alternating single-lane closures starting next week.

The Department of Public Works announced Friday that there will be alternating single-lane closures on the bridge from Monday through Friday at 6 p.m. to 6 a.m.

The demolition of the Rachel Carson Bridge upstream sidewalk is the reason for the closures.

The work is part of the $24 million Rachel Carson Bridge project, the department said.
