I took advantage of the very light Thanksgiving morning traffic into and around Boston to do some more 'research' into the new route signage that has been showing up around the city which MassDOT says is the work of an 'unknown organization.' My 1 1/2 hour trip took me up MA 3 to I-93 North to the Mass Ave exit, all at or above (slightly, of course) the legal speed limit. Here's signage for traffic heading from Mass Ave toward I-93 North and the Mass Pike: I was most interested in the 3 sign stack for North I-93/US 1/MA 3 because this will be similar, according to the plans, to the route marker signage, with the exception of the arrow, that is to appear along the SE Expressway at the conclusion of the current sign replacement project (assuming it is ever complete). I took a left toward Mass Ave and some interesting route signs appeared: Here are more mysterious MA 2A signs. Based on the signage it would appear the I-93 on-ramp and Melnea Cass Blvd intersection...
Because every road has a story.
