The Commonwealth is beginning the process of considering a replacement to the Maurice Tobin Bridge, opened in 1950 and a key cog in Greater Boston’s transportation network.

The Ghostbuster:
I assume the new bridge will be a double-decked bridge like the existing Northeast Expressway is from Interstate 93 to 5th St.

I think it would have to be, given space limitations.

In a perfect world, the new Tobin Bridge would be built on a new alignment, leaving I-93 near Sullivan Square and meeting up with the existing alignment in Chelsea near Rt 16. You'd eliminate two curves and would have improved ramps to/from I-93 that occur "ON THE RIGHT". And it looks like a mostly industrial area. (And that perfect world would have this become I-95 since you'd be able to build the rest of the Northeast Exp'y out to 128).
Anyway...
I wonder if in the 'list of possible alternatives', when it comes out (still a ways to go for that), if such an alignment would be thrown out there for consideration, or what other options they'll come up with. Seems like building a double decker bridge of that length in this day and age isn't the most ideal (especially if you're on the other coast).

What about a tunnel from MA 1A from the north end of the Callahan/Sumner Tunnels to just before Alington St?
