The 2019 International Accelerated Bridge Construction Conference being held this morning at Florida International University. Hundreds of engineers, consultants and government officials gathering at FlU to discuss automation and a new ultra-high performance concrete that's so dense virtually nothing can penetrate it, including water. FIU Dr. Atorod Azizimamini says this will significantly increase the life of bridges while reducing the cost to build them. They will not be discussing last year's deadly bridge collapse the NTSB blames on design error.
