After Months of Performing Sinkhole Repairs, the City of Pittsburgh and PWSA Announce That 10th Street Will Reopen As Of Thursday, 10/8

After a year of complicated work by several agencies and utilities to address a sinkhole and other damages, 10th Street in Downtown Pittsburgh is finally reopening on Thursday, 10/8.

Pittsburgh Public Safety officials responded to the sinkhole on October 28, 2019, which was so large (60 by 35 by 18 feet deep) that it swallowed the rear of a Port Authority bus. The driver of the bus and its riders were safe, but Public Safety’s next concern was the stability and safety of steam lines, water and sewage lines, and communications infrastructure perched below the street’s unsupported, cantilevered slabs of concrete. With the assistance of Allegheny Crane Rental and DiPasquale Engineering, officials ultimately brought a crane to the scene to carefully remove the bus while not further disrupting the infrastructure below.

The City’s response was overseen by Chief Operations Officer Kinsey Casey and included work by Public Safety, Public Works, and Mobility and Infrastructure. Responding utilities and companies included Duquesne Light, Peoples Gas, Comcast, Verizon, Port Authority, Pittsburgh-Allegheny County Thermal (PACT), and the Pittsburgh Water and Sewer Authority. Officials from the adjacent Westin Pittsburgh hotel were also helpful throughout the work.

At the end of the project, crews completed the following:

  • Added approximately 746 tons of stone backfill to the sinkhole
  • Replaced 2,097 square feet of bricks
  • Poured approximately 395 tons of concrete
  • Logged over 1,100 hours of work to complete the project
