Portion Of Parkway North To Close

ROSS TOWNSHIP, PA — Another Pittsburgh parkway will partially close next week, but the effects will not be as severe as the current partial closure of the Parkway East due to the Commercial Street Bridge replacement project.

The Allegheny County Department of Public Works on Friday announced that a portion of the Parkway North in Pittsburgh, Ross and Ohio Township, will be closed overnight Monday through Friday.

The closures are necessary to demolish Jacks Run Bridge No. 3, which carries Jacks Run Road over the parkway between Bellevue Road/Bellpark Drive and Kane Lane in Ross.

Here's the closure schedule:

Monday night (July 20) to Friday morning (July 24)

• The parkway northbound (outbound) will be fully closed between the McKnight Road/Evergreen Road exit ramp (Exit 4) and the I-279 North on-ramp from Camp Horne Road from 9 p.m. to 5 a.m. nightly.
• The parkwayI-579 HOV northbound (outbound) lanes will be closed from 8 p.m. to 6 a.m. nightly.
• The left lane of the parkway southbound (inbound) under Jacks Run Road will be closed from 7 p.m. to 6 a.m. nightly.

Friday night (July 24) to Saturday morning (July 25)

• The parkway northbound (outbound) will be fully closed between the McKnight Road/Evergreen Road exit ramp (Exit 4) and the parkway on-ramp from Camp Horne Road from one hour after the 6:40 p.m. Pittsburgh Pirates game at PNC Park concludes (or 9 p.m. if the game is postponed) to 9 a.m.
• The parkway/I-579 HOV northbound (outbound) lanes will be closed from one hour after the Pirates game concludes (or 8 p.m. if the game is postponed) to 10 a.m.
• The left lane of I-279 southbound (inbound) under Jacks Run Road will be closed from 7 p.m. to 9 a.m.

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

When I-279 northbound (outbound) is fully closed:

• Outbound parkway traffic will be detoured using McKnight Road, Babcock Boulevard, Rochester Road, Lowries Run Road and Camp Horne Road.
• Union Avenue traffic to the parkway northbound will be detoured using Gass Road, Highland Avenue, Perry Highway, Rochester Road, Lowries Run Road, and Camp Horne Road.
• Cemetery Lane traffic to the parkway northbound will be detoured using Perry Highway, Rochester Road, Lowries Run Road, and Camp Horne Road.

Periodic closures of the parkway/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.

The parkway/I-579 HOV lanes are maintained by (PennDOT). The section of I-279 near Jacks Run Bridge No. 3 is used by an average of 73,367 vehicles daily.

The $2.8 million project is being funded by Federal Highway Administration money.

Public Works closed Jacks Run Bridge No. 3 in July 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.
