I remember the old RI-4 to RI-2 ending well when I was a kid. Going that way meant having to go through the infamous Wickford rotary, which was like the rotaries that used to bedevil the Boston area. By the time I was old enough to drive in 1989-90, Route 4 had been completed.
I-95 in that area is actually designed for most of the traffic southbound to get off at Route 4, which is certainly true in the warm months. The state has actually gotten better with signage and pacing to tell drivers which way they’re going, and to stay right on I-95 to continue south. Besides the nasty lane drop just after the exit on I-95 that needs to be fixed…….well, that’s another post.
The state actually uses North Kingstown as a control city, and used East Greenwich in the past. Narragansett is a control city on RI-4. Newport is a little tougher, as RI-4/US-1 don’t really go near there, and the other towns in South County aren’t really big enough to warrant control city status, certainly not on I-95.
As has already been mentioned, pretty much everyone heading south on I-95 knows that RI-4 is the best way to get to the beach and to Newport, warts and all (you can’t forget it on many summer evenings). Many RIers even call it the road to the beach.
In fairness, I can’t understand why RIDOT uses the signage it does, or uses such tiny fonts for some of their auxiliary signs. I suspect that a not insignificant number of South County residents are secretly happy that their towns aren’t named more prominently on highway signs.
