FIGG Bridge Engineering has strong Pennsylvania ties, with an office in Exton in Chester County and a track record of major projects across the state.

The Florida-based company's work includes the Pennsylvania Turnpike bridge spanning the Susquehanna River just south of Harrisburg. Another major project is the turnpike bridge spanning the Allegheny River near Pittsburgh.

Also, FIGG and two other companies carried out a 2014 SEPTA contract to replace the Crum Creek Viaduct on the Media-Elwyn Regional Rail Line near Philadelphia,

The bridge that collapsed Thursday killing six and injuring ten more was a pedestrian bridge on the campus of Florida International University near Miami. It was assembled next to the road in a unique "accelerated bridge construction" method and hoisted into place on Saturday. The 174-foot span cost $14.2 million and crossed a seven-lane highway. It wasn't scheduled to open to foot traffic until next year.

FIGG Bridge Engineering issued a statement following the collapse, saying, "In our 40-year history, nothing like this has ever happened before."

Robert Bea, a professor of engineering and construction management at the University of California, Berkeley, told the Associated Press it's too early to know exactly what happened, but the decision to use what the bridge builders called an "innovative installation" was risky, especially because the bridge spanned a heavily traveled thoroughfare.

"Innovations take a design firm into an area where they don't have applicable experience, and then we have another unexpected failure on our hands," Bea said after reviewing the bridge's design and photos of the collapse.

A Pennsylvania Turnpike Commission spokesman couldn't immediately be reached early Friday to say whether the Florida collapse raises any concerns about FIGG designed bridges in Pennsylvania, or whether there have been any problems with the bridges.

FIGG Bridge Engineering apparently does work in many states.

A FIGG designed bridge on the Minnesota-Wisconcin border

in late 2017. The 2,592-structure cost $81.5 million.

In Pennsylvania, the turnpike bridge over the Allegheny was finished in 2010,

It cost $193.6 million and took three years to build. It was built slightly downstream from a bridge it replaced.

According to pghbridges.com, the 2,350-foot bridge consists of six spans, with the road surface 120 feet above the river. An Illinois firm did the construction, with a third firm managing construction for the turnpike commission.

The turnpike bridge south of Harrisburg opened in 2007 and cost $150 million. It actually consists of two separate three-lane bridges with eight feet between them. It replaced a bridge that opened in 1950. As was the case with the Florida bridge that collapsed, a separate firm handled the construction.
