There’s one in my area. On Wednesday, a semi overturned while going through it. I’m not a fan of roundabouts, but the one in my area is on the city’s bypass so it’s way better than driving through the construction zone in town.
They took out the traffic signals in the construction zone and replaced them with four-way stops just so the drivers who have the right-of-way can create an awkward situation by just sitting there and staring at the other drivers waiting for them to move. Now I just avoid that construction zone.
