Roundabouts in Waterloo Region

Since last year, several roundabouts (often found in Europe) have been constructed in the cities. There is one being built in between Waterloo and Elmira on the 86. The road closed due to the roundabout and the bridge being rebuilt over the Conestoga River. Truck driving companies have been complaining that the roundabout is to small for trucks. Also, horse and buggies will have travel down the road through a pipe undeneath the road. But the pathway they have built seems to be not wide enough for buggies going opposite directions of the same side of the road. I hope that the engineers know what they are doing because this is a major route not an oridinary street in the city
