Jacks Run Bridge No. 3 in Ross

PITTSBURGH – The Department of Public Works today announced the schedule for next week’s overnight closures of a portion of I-279 in Pittsburgh, Ross, and Ohio Township. The closures are necessary to demolish Jacks Run Bridge No. 3, which carries Jacks Run Road over I-279 between Bellevue Road/Bellpark Drive and Kane Lane in Ross.

I-279 southbound (inbound) will be fully closed between the Camp Horne Road exit ramp (Exit 8) and the I-279 South entrance ramp from McKnight Road during the following times next week:

  • From 9 pm Monday, June 22 through 5 am Tuesday, June 23
  • From 9 pm Tuesday, June 23 through 5 am Wednesday, June 24
  • From 9 pm Wednesday, June 24 through 5 am Thursday, June 25
  • From 9 pm Thursday, June 25 through 5 am Friday, June 26
  • From 9 pm Friday, June 26 through 9 am Saturday, June 27

Also, the left lane of I-279 northbound (outbound) will be closed from 7 pm to 6 am nightly from Monday night to Saturday morning.

This schedule is weather-dependent. Demolition work cannot take place during heavy rainfall or when lightning is in the area.

When I-279 southbound (inbound) is fully closed:

  • I-279 southbound traffic will be detoured back to I-279 using Camp Horne Road, Lowries Run Road, Rochester Road, Babcock Boulevard and McKnight Road.

  • I-279 southbound traffic to Union Avenue in Ross will be detoured using Camp Horne Road, Lowries Run Road, Rochester Road, Perry Highway, Highland Avenue, and Gass Road.

  • I-279 southbound traffic to Cemetery Lane in Ross will be detoured using Camp Horne Road, Lowries Run Road, Rochester Road, and Perry Highway.

Periodic closures of I‑279 and the I-279/I-579 HOV lanes are expected through August. A detailed schedule of closures for the following week will be released every Friday until the work is complete.

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.
