For anyone who comes to Connecticut, be aware that Rte 15, Merritt Parkway, is a non-commercial vehicle road with low bridges - as far as I know this includes campers not being allowed - but some people argue about that. The Merritt is known for its unique, and low, bridges. Raising those bridges would be a massive undertaking. During repair / reconstruction of it years ago there was a lot of meetings about how to save the bridges. It also used to be very wooded, with trees down the middle between north and south lanes. For "safety" reasons they have cut most of the trees down, and cleared the sides farther back. I know it's for safety, but it is a shame, as it used to be a beautiful road to travel. Now it still is more wooded than a typical highway, but not as nice as it used to be. The biggest problem is how fast people travel on the road. Then during rush hour it is packed with traffic.
As I said, I understand the safety part, but it is too bad that so many cool things seem to have to be destroyed or changed in the name of "safety", when the big gorilla in the room is that people don't pay attention while driving and don't use common sense - and don't read the road signs.
