P.J. McArdle Roadway Viaduct No.1

The City of Pittsburgh, PA, will accept sealed bids Sept. 16 for surface preparation and coatings application on the P.J. McArdle Roadway Viaduct No.1.

The 548-foot-long viaduct includes a 215-foot-long riveted-steel, Parker through truss main span. The viaduct crosses over Norfolk Southern Railroad and carries Lower P.J. McArdle Roadway. Built in 1933 and previously rehabilitated in 1960, Viaduct No. 1 offers panoramic views of downtown Pittsburgh.

The project includes coating new and existing structural steel surfaces, including stringers, floor beams, diaphragms and cross bracing. The steel will be abrasive blast-cleaned to a Near White finish (SSPC-SP 10) and recoated with a three-coat organic zinc-epoxy-urethane system selected from NEPCOAT List B.

The contract requires containment of the existing lead-bearing coatings (SSPC-Guide 6) and hazardous waste disposal (SSPC-Guide 7).

The project also includes fabricating and erecting 483,600 pounds of new structural steel, in addition to applying a penetrating sealant protective coating to a total of 3,456 square yards of reinforced concrete superstructure and substructure surfaces.
