Will be interesting to see the comparison shots. Funny over here they seem to put round-abouts in to improve traffic flow vs. the intersections. I suppose will depend on how the flow works, maybe if mostly one-sided a main highway straight through, with interchanges on the opposing sides. Looks difficult with 5 points going there.
Yes
Over here the round about causes a lof of traffic
With the fly overs and interchanges the traffic is reduced drastically
Will surely update you when it is completed
