In Greene County, the Wright State Way pedestrian bridge over Interstate 675 serves a similar purpose, connecting the Beavercreek and Fairborn sides of the highway.
Local officials noted that Wright State Way was constructed differently than the Florida bridge and appears to be in good condition.
The 950-ton pedestrian bridge that collapsed Thursday near Miami was built using an innovative technique called “Accelarated Bridge Construction.”
When the Wright State Way pedestrian bridge was built in 2015, only the trusses were prefabricated and shipped to the site on I-675 near Wright State University, according to Beavercreek City Engineer Jeff Moorman.
All of the other work, including the pilings, abutments, piers, bridge decking and railing, were installed separately on site, “much like many other bridges throughout the state,” Moorman said.
“The bridge design, methods and materials used for the bridge in Beavercreek are standard for the industry and have been used successfully at many other locations,” he said.
The Wright State Way bridge, which cost $3.5 million to build, spans 467 feet and is 12-feet wide. It was designed by LJB Inc, a civil and structural engineering firm. It connects the WSU campus and Fairborn to the city of Beavercreek.
The bridge that collapsed in Florida spans 170 feet, and was being built at a cost of $14.2 million. It was done in collaboration between Miami-based contractor MCM Construction and Figg Bridge Design, based in Tallahassee, which also designed the iconic Sunshine Skyway Bridge across Tampa Bay. The Florida bridge was to connect the FIU campus for pedestrians to the city of Sweetwater.
Moorman said the Wright State Way bridge is inspected annually, the last in October.
“The report showed all components of the bridge to be in excellent condition,” he said.
At least one ABC bridge has been installed in Ohio. Two sections on I-75 were put in place over two weekends in 2015 to cross over U.S. 6 in Wood County. The work on the $7.8 million project was done by Kokosing Construction Company Inc. and Arcadis, according to ODOT.
ODOT reported the method was preferred because of minimal traffic disruptions and is being used in at least eight states, including Pennsylvania, Michigan and Indiana.
ODOT spokesman Matt Bruning said the project on I-75 is considered an “accelerated construction,” it was “vastly different” than the bridge that collapsed in Florida.
“The construction portion was not accelerated. It was the installation that was accelerated,” Bruning said. “We didn’t lift that bridge at all. It was a lateral slide.”
In addition, Bruning said from what he understands of the Florida bridge’s design, it’s “completely different” than anything in Ohio.
“We don’t have anything within the ODOT system that would match it,” he said.
ODOT inspects every bridge in the state’s network on annual basis. Bruning said the federal standard for bridge inspection is every two years.

5 THINGS TO KNOW ABOUT ACCELERATED BRIDGE CONSTRUCTION
The a 950-ton pedestrian bridge that collapsed Thursday at Florida International University in Miami-Dade County used an innovative technique called “Accelerated Bridge Construction.”
How it works
The ABC method is meant to reduce risks and interruptions to commuters, pedestrians and workers. ABC projects are constructed off site and moved to the site to be put together and anchored in place.
Completion date
The 170-foot, $14.2 million bridge was put into place last week, taking less than six hours. The project was expected to be completed in 2019.
Passageway
The bridge was supposed to be a safe way to cross a six-lane highway and provide a plaza-like public space for the school’s campus to the city of Sweetwater to the north.
University’s role
FIU hosts the Center for Accelerated Bridge Construction, a national center for education about and promotion of this construction method. The University City Bridge was designed to survive a Category 5 hurricane.
Design team
Designed as a cable-supported bridge, the project was a collaboration between MCM Construction, a prominent Miami-based contractor, and Figg Bridge Design, based in Tallahassee, the Miami Herald reported. Figg is responsible for the iconic Sunshine Skyway Bridge across Tampa Bay.
