Interstate I-395 Northbound near Exit Number Just before the Mass. Avenue exit
This is I-395 northbound, north of the river, heading towards Mass and New York Avenues in the section that goes underneath a lot of the city. The posted limit is 35 (!) on a six-lane divided "interstate" highway, and apparently there is a new photo radar. It may be one of their mobile units, I don’t know; never saw it until a *warning* came in the mail.
