Fern Hollow Bridge

The Fern Hollow Bridge collapsed in the early hours of January 2022.  Thankfully the collapse only resulted in a few injuries and no fatalities.  However, this route carried more than 20,000 vehicles per day and an emergency replacement was needed.  PennDOT chose precast concrete for the new bridge – a three-span structure using twenty-one (21) prestressed concrete 33/95.5 PA Bulb Tee Beams, weighing more than 100 tons and roughly 152 ft in length.  The aggressive schedule enabled the bridge to be open for traffic less than a year after the initial collapse.
