Demolition of Pittsburgh-area bridge by explosion postponed

(WKBN) — The Pennsylvania Department of Transportation’s plans to demolish a bridge via explosion have been postponed until Thursday.

The demolition of the Interstate 376 (Commercial Street) Bridge in Edgewood Borough and the City of Pittsburgh is expected to occur sometime Thursday, weather permitting, according to PennDOT.

The bridge is between the Squirrel Hill Tunnel and the Edgewood/Swissvale (Exit 77) interchange.

The explosive process will occur after crews and emergency personnel have cleared the blast radius on the ground and in the air and have declared the zone safe for explosion, according to PennDOT.

The public can view the explosive demolition via a live feed camera on the 511PA website.

The bridge is being replaced as part of one of the largest lateral slide projects in Pennsylvania. According to PennDOT, the project will slide the new bridge onto the existing alignment of I-376 (Parkway East).

The $95 million project began in June of 2024 with the reconstruction of the westbound I-376 off-ramp to Forest Hills/Wilkinsburg (Exit 78B). The overall project is anticipated to conclude in the summer of 2027.
