PITTSBURGH — PITTSBURGH (AP) - A Pittsburgh bridge is closed over the weekend to repair damage caused by a construction fire last year.
Traffic on the Liberty Bridge closed in both directions at 3 p.m. Saturday and will remain closed until 11 a.m. Sunday.
The northbound side of the Liberty Tunnel is also closed. All traffic will be detoured.

Crews will also repair an expansion joint that crosses the full width of the bridge.

- Contractor: First phase of Liberty Bridge repairs almost complete (Sept. 15, 2016)
State transportation officials and the federal Occupational Safety and Health Administration have said hot residue from a blowtorch ignited plastic piping and a construction tarp on Sept. 2.
A 30-foot chord designed to hold 2.4 million pounds of pressure buckled during the blaze. Its failure could've caused the bridge to collapse.
