Crews Begin Sliding New Bridge Into Place On I-376

PITTSBURGH — Days after the old Commercial Street Bridge was imploded, the new bridge is being slid into place.  The Penn DOT crews started the lateral slide of the new I-376 Commercial Street Bridge around 10 a.m. Sunday.  In all, PennDOT says the fully constructed bridge will move 102 feet into its new place. It’s being moved with a skidding system that slowly aligns it with the Parkway East.  Each of the 42 skid shoes can operate independently, with integrated hydraulic jacks used to lift the load from its temporary supports and set it down on the permanent bearings.  PennDOT didn’t say when the slide could be completed
