It's settled. The 35/30 interchange should have been a giant roundabout.
This is true (and I rarely signal tbh), but in the smaller ones it's not always clear which exit you are taking when you signal, the time between one exit and the next isn't much.
I'm a fan of round a bouts (especially if everyone eventually figures them out), but I know one or two that the small size makes them more challenging.
Actually the city?I never underestimate the timidity and lack of discernment by Iowa drivers.
P.S. I'm from Chicago, so that may be a factor in my perspective.
This contractor should never get an Iowa DOT contract again, what a complete fail on their part.
We seem to keep using roundabouts for aesthetic reasons rather then using them where they are actually effective. I cannot stand roundabouts in the middle of residential neighborhoods where there is very little traffic. Roundabouts that replace stoplights and stop signs at busy intersections are awesome! Ill take a roundabout over a stop light every day of the week.Roundabouts when used appropriately are good. In the US they often aren’t. Certain cities put them in where 95% of the traffic goes one direction. They aren’t a replacement to two way stops and they need to be designed so you don’t basically have to stop to enter them.

From what I heard, it was the surveying subcontractor that was to blame.
I mean, while the delay sucks, we're getting this bridge at a discount now due to the $5k\day penalties on the contract, so it works out either way for the DOT
They aren't going to feel bad about anything. They'll just think you're a ****.Honk at them if they and make them feel bad for not understanding how to drive.

I don't think a roundabout is more effective in doing either of those then a stop sign is (again we're talking low traffic areas here), but I'm no expert on the matter.I think roundabouts in those areas are used to try to get people to slow down to a speed more proper for a residential neighborhood. They are supposed to reduce accidents in those neighborhoods as well.

At least around here they are difficult to navigate at 15 mph. That’s one of the problems with them. If I have to slow down that much I’d rather just have a stop sign.A stop sign isn't placed to control speed though. It's used to give right of way to a specific leg or legs of an intersection. Same with a yield sign. Mini roundabouts in neighborhoods do help control speed, as it's hard to navigate them at 40 mph. Traffic signs can be ignored but make it easier to assign blame in the case of an accident, which is the source of their deterring power (along with tickets, obviously).

They shouldn’t be slowing people down that much. It shouldn’t be cutting speed in half because that is what they do. They put them on 35 mph roads and spam them in places that rarely have traffic that isn’t going straight on the main road.Sounds like they're working, then!
I think in those cases, roundabouts are more cost effective. You don't have to spend electricity on the lights ect. Of course this is what I was taught in my traffic engineering class over a decade ago so I'm not an expert on it either.
