@jheartney @goatsarah Key word "generally". The roundabout is better a lot of the time, and many traffic light crossings would benefit from being turned into roundabouts, but it's not a strictly better solution in every single case.
It depends on the traffic volumes and the space available to build a roundabout that fits the traffic volumes. This could be one of the cases where the roundabout was rationally a mistake.
Or it could be an irrational fear or annoyance with roundabouts, or the mentioned corruption.
