Breezewood, PA is pretty infamous: I-70 has a stoplight with US-30, where you turn right, go through a second stoplight, turn right again, and then get back on I-70. It and the I-78 approach to the Holland Tunnel are the only two places where the interstate has a traffic light, although the road is 35mph immediately in front of it in PA (I don't know what the speed limit of the NJ road is).
Freeways ending in stoplights are actually fairly common, although they usually have lots of advance warning saying "FREEWAY ENDS." 50mph and 55mph roads having stoplights on them aren't particularly uncommon, particularly in rural areas.
