It was assembled using a different process called Accelerated Bridge Construction (ABC).
State officials say at two bridges exist in Indiana built using the same process, which is a method touted as a safer alternative to conventional bridge building, where now bridges can be assembled off-site and moved into place.
The pedestrian bridge in Florida had just been installed and wasn’t open for use prior to the collapse that killed at least six people.
In 2014, the Milton-Madison Bridge at the Kentucky state line was built right next to the existing bridge and slid into place.
At the time that was longest bridge slide project in North America.
Another much smaller bridge was done the same way along I-70 in Wayne County last year.
State officials say bridge building projects used to have roads shut down for months, but with ABC would only impact traffic for a few days.
“You do that so that way it minimizes the disruption to traffic,” said Jeremy Hunter, Bridge Design Director for INDOT. “It's typically improved safety for our construction workers because there is less exposure to traffic and those are the main benefits.”
INDOT officials say they haven’t had an issue with either bridge, which are inspected every two years.
“When it goes to construction there are specifications that we have. If there are additional specs needed, the engineer of record and the contractor is held to those specifications on how the bridge should be built,” said Hunter. “ We continually look at them and if we see any deterioration issues then we can make repairs.”
