PITTSBURGH — The Fern Hollow Bridge in Frick Park was built over 14 months in 1972 and 1973 for $1.2 million, replacing a 70-year-old bridge that was closed because it was deemed "hazardous" and to have "extreme deterioration," according to stories at the time.
About 50 years later, that new bridge is now in crumbled pieces in the ravine below after collapsing Friday morning, injuring 10 people.
The 1970s bridge was designed by the engineering company Richardson, Gordon & Associates of Pittsburgh, a renowned company that had also designed the Fort Pitt and Fort Duquesne bridges Downtown, among others.
