If you've worked the R or overnight N, you may have noticed a noticeable indentation on the right-hand side tunnel wall after departing Whitehall heading into Montague tube. Could that have been for a projected Manhattan-Staten Island tube? The angle seems to indicate it would pass between the Whitehall and Governor's Island ferry terminals, so it's inconclusive.

Not really a bellmouth, but there's a very noticeable setback in the Queensbound wall at the extreme southern end of City Hall. It may indicate that the BMT Broadway Line was intended to continue due south on Broadway rather than curving west under Saint Pauls Church and south to follow Trinity Place. But by 1908 the East Side IRT already occupied Broadway below Park Row/Vesey Street, a mere two blocks south. This was several years before the BMT was built along Broadway.

There was also some speculation that the IND Hudson Terminal stub was intended to tie in what is now the aforementioned Trinity/Montague line. They line up perfectly immediately to the west of what is now Ground Zero, with only a few feet separating the northernmost uptown entrance of the now-closed Cortlandt Street station and the southernmost entrance to the Chambers/WTC/Park Place complex.
