Talk:Boston Harbor tunnel

What about the Blue Line tunnel?
Is there not yet another tunnel carrying the blue line? Strangely, I can find very few details about it, aside from this:

My sense is that 1) The Blue Line tunnel is the oldest of the four, several years older than the Sumner and 2) It is somewhere between the Sumner Tunnel and the Ted Williams Tunnel.

It must be large enough to carry the Blue Line both ways.

But, I could be confused..... LCarl (talk) 20:30, 29 August 2023 (UTC)

Is this really a disambiguation page?
It seems to me more like a list of all the tunnels under Boston Harbor. I mean, it is clearly trying to be that, but perhaps that does not prevent it from being a disambiguation page. I guess I thought DAB pages were mainly used in cases where the same term is used for different things, like “Lion” can be an animal or a version of macOS. But, Boston Harbor Tunnel is a general category of which these things are members. LCarl (talk) 17:00, 19 September 2023 (UTC)
