Massachusetts Roads - I-93/MA 3/US 1 - SB Big Dig
I-93/MA 3/US 1
SB Big Dig
Video tour through the tunnel (4 MB)
This sign, as you can see, is about 3 miles north of Boston, and is the northernmost of the new SB signage.

Entering I-93 SB from the new Leverett Circle ramp, which tunnels underneath the site of the old ramps but must emerge to join the highway. The ramp itself is MA 3 SB. The girders and other tall metal things left here are some of the final remnants of the elevated Central Artery.

Almost done with the tunnel, but I just want to point out two things. For one, note that only one BGS separate Mass from Pike (fourth picture from the end and the next one to follow both have MassPike, which sounds more like a business than a road). Secondly, you can see a merge in the last photo, but that merge, and the offramp immediately before it, are both coned off without any advance signage. Either these ramps only saw temporary use during various phases of construction, or they'll be marked and opened when all is said and done. Anyway, for some reason I-93 SB shrinks to two lanes in this area, which is unfortunate because the old Artery was clogged enough with three SB lanes.

Finishing up the new SB signage; the first pic, just to remind you, sports "MassPike", but it also demonstrates the yellowish transition lighting that helps drivers get adjusted to entering and exiting the tunnel. You can tell because the photo came out well.
