Exit 1 of I-93 S is now designated Exit 1A with the destination remaining the same. The segment of I-93 S to I-95 N is now signed as “Exit 1A: I-95 N / US-1 S / Dedham / Portsmouth NH”.

They are both designated “Exit 1A:” in your post. I’d bet one is “1A” & one is “1B”… Which is which?

The exit leading to I-95 N is exit 1B. Sorry for the confusion.

Fixed. Should give a “Keep Right” or “Keep Left” now too…
