It took a year to build the Empire State Building, and 5 years to build the Hoover Dam yet current estimates for the Francis Scott Key bridge rebuild are near 10 years. Why is this? Have we regressed?
In: Engineering
The Key bridge as an overall project took 29 years to build (4-lane approaches completed in 1999). This doesn’t include design and procurement time, 2-5 years or so.
