P. J. McArdle Roadway will be closed from Arlington Avenue to S. Ninth Street for approximately one year to allow for the reconstruction of Viaduct No. 1 over the Norfolk Southern Railway tracks.
The $7 million construction project consists of a deck replacement, steel repairs and painting the truss bridge over the railroad tracks, and a total substructure and superstructure replacement of the viaduct between the truss and S. Ninth Street. Cost of the project will be shared by the Federal Highway Administration, 80 percent, Pennsylvania Department of Transportation, 15 percent and the City of Pittsburgh five percent.
Viaduct No. 1 has been open under a three-ton weight limit since December of 2007 when it was reopened after a four-month closure for emergency repairs.
The construction contractor is Beech Construction Inc. The construction contract administration and inspection will be performed by McTish, Kunkel & Associates. The engineering design was completed by ms consultants, inc. at a cost of approximate $1.5 million.
Port Authority riders should be alert to the temporary relocation of bus stops in the affected area.
