>>1101468>why have them intersect with stop lights halting traffic?Cost. At grade intersections are much cheaper. If you want to check out a freeway with a huge variety of interchanges look at highway 400 in Ontario on Google maps. Since most of the highway north of thw city of Barrie just cuts through forest, the interchanges are designed only to the standard that traffic in the rural areas required. Like look at this;
On the left theres a parclo interchange where you exit the highway to traffic lights, but you enter from an arterial road lane.
On the right it's a rural interchange where you exit the highway to a stop sign, and you enter kind of on a right in right out interchange.
It's just done for traffic need and cost
