National Transportation Safety Board updates investigative report into Fern Hollow Bridge collapse

The National Transportation Safety Board released a preliminary investigative update about the Fern Hollow bridge collapse nearly a year ago.

The bridge collapsed on Jan. 28, 2022, falling about 100 feet to Frick Park below.

The update states that engineers have analyzed portions of the bridge’s legs and investigators have interviewed personnel involved in the maintenance and oversight of the bridge. They’ve also examined other bridges in the state with similar construction features.

The docket, made public on the NTSB’s website today, contains 2,137 pages of information covering various aspects of the investigation and includes preliminary reports, documents pertaining to the materials and construction specifications of the bridge, maintenance records and manuals addressing bridge management and inspections. It can be viewed here.

Analysis, findings, recommendations and probable cause determinations related to the collapse will be issued by the NTSB in a final report at a later date.

The full update is available on the NTSB’s website.
