US 412 between Dyersburg and Jackson, TN: Is there another highway like it?

[Tom958]

Yes, I mentioned in the OP that the highway in question was like a rural version of a Jersey freeway. The big difference is the presence or lack of restrictions on left turns, though I think that with Jersey freeways, that's mainly due to a chronic lack of median width to accommodate left turn pockets.

Regarding Jersey freeways, those corridors are often are carrying heavy volumes of traffic, often moving at 50-70 mph (regardless of speed limit), and having left turns would simply be dangerous. The right turns are already bad enough. They're effectively substandard freeways.

Yes, that was a dumb thing for me to say. For safety reasons, it's unlikely that at-grade left turns would be added to most Jersey freeways even if it was feasible to do so.
