The removal of a bridge over busy I-95 in Fort Lauderdale was initially estimated to take 30 days. Using Accelerated Bridge Construction (ABC), contractor Mammoet was able to do it in a matter of hours. Their plan involved hoisting the bridge off of its abutments and moving it to another location for demolition. This avoided the risk to nearby traffic. The challenges involved in this method were overcome by a combination of teamwork and communication. Across the country, state DOTs are changing the way they operate thanks to ABC technologies.

Key Takeaways:

  • The contractor Mammoet came up with a bridge removal plan that could be completed in a matter of hours.
  • Accelerated Bridge Construction technologies are altering the way state DOTs operate.
  • The technology has safety advantages because crews can perform demolition without traffic moving below.

“Six trains of eight-line self-propelled modular transporters equipped with 250-ton jacks hoisted the bridge off its abutments in May for relocation south along I-95 to an offramp for demolition.”
