I-279 and the I-279/I-579 HOV lanes are maintained by the Pennsylvania Department of Transportation (PennDOT). The section of I-279 near Jacks Run Bridge No. 3 is used by an average of 73,367 vehicles daily.
Swank Construction Company of New Kensington is the primary construction contractor for the $2.8 million project, which began on April 27, 2026. The Federal Highway Administration (FHWA) is funding the entire project, and PennDOT is overseeing the federal funds.
Public Works closed Jacks Run Bridge No. 3 on July 3, 2025, after inspectors identified corrosion in the bridge’s only pier. The bridge carried an average of 4,631 vehicles daily. Construction of a new bridge will take place as a separate project that is expected to begin next year.
