4 years to build in the first place

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.
