10th Street Sinkhole Update


The City of Pittsburgh Department of Mobility and Infrastructure – working with partner agencies and utilities – has determined that 10th Street between Penn and Liberty avenues Downtown will remain closed an estimated eight weeks after a sinkhole occurred there early Monday morning. 

Penn Avenue reopened early today following the removal of a Port Authority bus from the sinkhole. Liberty Avenue is also open. Traffic continues to be impacted around the area however, and a small portion of the Penn Avenue bike lane is closed, forcing bicyclists to use the traffic lane. 

Today a contractor is removing concrete and debris from the hole, and will then utilities will work on securing the fiber infrastructure at the site. Once that work is completed the Pittsburgh Water & Sewer Authority will assess any damage to water, sewer and storm lines at the site and make any repairs needed. 

There are a host of utilities impacted by the sinkhole, which complicates the restoration effort. In addition to PWSA there is also below-ground infrastructure at the site by Duquesne Light, Verizon, Peoples Gas, and PAC Thermal (PACT).  

The street cannot be restored until all utility repairs are complete. Once those repairs are done, the sinkhole will be filled up to the subgrade level and a new concrete street will be poured. Sidewalks and curbs in the affected area will also be restored. All of those repairs will take an estimated eight weeks to complete. 

Businesses in the area may experience intermittent outages of water or utility service as repairs are made. Entry to the Westin Pittsburgh Hotel is being accommodated from Liberty Avenue at 10th Street. 

Further updates will be issued as necessary.
