It took nine years from the bond issue (1968) to completion (1977).
The estimate of 10 years to reopening is reasonable and consistent with what it took to build it originally when you take into consideration the four years of project prep-work that happened between the bond issuance and the start of construction.
Frankly, I think ten years is pessimistic. If the existing approaches can be salvaged it will take a good year or two off the construction time. They don't have to do any new geological studies to rebuild the cassions.
Is there a reason that prep-work needs to be done again? Genuinely don't know: presumably the formerly built bridge had engineer-approved plans where all the math and physics were worked out and validated.
I mean, aside from clearing the wrecked bridge so that you can build it in the same spot.
I'm no bridge engineer but if the collision caused enough stress across the entire structure to the point of causing fractures in underwater foundation blocks then I'd imagine they might have to dismantle them as well.
