    Southbound I-579 Crossover Removal this Weekend in Pittsburgh

    September 03, 2025

    Pittsburgh, PA – PennDOT is announcing the removal of the southbound I-579 crossover in the City of Pittsburgh, Allegheny County will occur Friday night through Sunday afternoon, September 5-7, weather permitting.

    Beginning at approximately 9:00 PM Friday, the current traffic configuration from southbound I-279 to southbound I-579 that was implemented on June 23rd will be removed. Crews from Swank Construction will work to reestablish the original traffic pattern through 1:00 PM Sunday with the following implementations:

    • Southbound I-279 traffic to southbound I-579 will use the normal right-hand off-ramp to the Veterans Bridge (Exit 2A).
    • The current left-hand exit from southbound I-279 to southbound I-579 utilizing the High Occupancy Vehicle (HOV) lanes will be closed.
    • The ramp from southbound Route 28 to southbound I-579 will reopen to traffic.

    Once the original configuration has been restored, crews will work in the closed HOV lanes in preparation for the upcoming northbound crossover, which is anticipated to begin the weekend of September 13-14. Intermittent lane restrictions may occur on I-279 during non-peak hours while the preparatory work occurs. Additional details will be provided in advance of the northbound crossover implementation.

    Crews will continue to conduct repair work to bridges on I-579. The long-term repair work follows previous inspection activities where the department found significant deterioration on several piers on I-579 and the I-579 HOV lanes. Out of an abundance of caution, traffic was shifted on mainline I-579 and completely removed from the I-579 HOV lanes while analysis was conducted.  The department performed hands-on inspections of 35 piers in this location. The project team has been in constant communication to safely and efficiently develop and implement repairs while minimizing the impacts to motorists. The repair plan makes necessary long-term repairs while maintaining as much traffic flow as possible.
