Part of I-279 Southbound and I-279/I-579 HOV Lanes to Fully Close 4 Nights Next Week

PITTSBURGH – The Department of Public Works today announced the schedule for next week’s overnight closures of a portion of I-279 and the I-279/I-579 High Occupancy Vehicle (HOV) lanes 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 15 through 5 am Tuesday, June 16
  • From 9 pm Wednesday, June 17 through 5 am Thursday, June 18
  • From 9 pm Thursday, June 18 through 5 am Friday, June 19
  • From 9 pm Friday, June 19 through 5 am Saturday, June 20

The I-279/I-579 HOV lanes will close in the northbound (outbound) direction at 9 p.m. on Monday, June 15; Wednesday, June 17; Thursday, June 18; and Friday, June 19 until the directional switch is made at 6 a.m. the following morning.

From 9 pm on Tuesday, June 16 to 5 am on Wednesday, June 17, there will be a single-lane closure on I-279 southbound underneath the bridge.

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.

Closures of I‑279 and the I-279/I-579 HOV lanes are expected to continue 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.
