Not impossible, but they did have to deal with gas leaks and a WW2 grenade, and this is a rail bridge on an actively used line.
Still, there's an undeniable sense of "why is this more expensive to replace than it was to build in the first place?" with a lot of infrastructure in the modern world.
Some firms prebuild bridges and slide them in. 20-30% more expensive apparently but a lot faster. Lets say $2M by quading it. Gas line is a nothinger, they would need to shut it down and reconnect it anyways. Grenade removal, they do it in war zones and it is not that expensive in my opinion.
wow "a quarter of a billion dollars" for that.
My guess is that with modular precast forms, it would be something $500k max!
Somebody pocketed some big amount of cash, I would guess.
