i ran a 12 mile traverse a ways back through a bunch of control because this very scenario panned out. two different contractors on separate phases of a highway build. turns out one of the contractors was coming off control that was set, artificially “northed” by a foot, then scrapped and replaced. ‘cept either nobody ever told them or they just ignored it.
about 3 months of re-design on a few flyovers, a couple of weeks of guys up on scissor lifts with jackhammers tearing down piers, and i’m sure somebody’s insurance premiums went up a bit. maybe an unemployed PE or RPLS or two…

We had a similar problem years ago.
Four lane road going through two adjacent housing tracts.
Half was being built then. After a few years the other half would be built as traffic required.
Miscommunication between developers and engineers.
In one tract it was decided to build the North half, the other built the South half.
We saw something was wrong when we put in curb stakes about the same time.
A temporary switch-over was put in that was used for a few years until the full four lanes were built.
Ha-Ha. No harm.
There was a 1200′ bridge in our portion that was also to have another parallel bridge next to it.
Luckily it was totally within the tract we were working on. No horizontal problems.
The bridge builder insisted on transferring all the vertical control out on the bridge themselves.
Managed to miss center match up by about 0.3 ft. Lots of grinding cured it.
For the life of me I don’t know how they let it get that far.
Maybe it was the classic we write 1.10 ft they read it as 1’10”?
