I just finished reading the article about the new traffic circle in Calais. I traveled the circle while working in the area. It must have been designed by the owners of a scooter.
Nearly two-thirds of the tractor-trailers I followed went on the curb. I fully admired the few that did not. Many of the smaller pickups and cars with trailers found the curb also.
There was room to enlarge the circle and properly make it safer and much more trucker-friendly.
I agree also with Ernest James about winter maintenance. It will be a challenge.
I though the new crossing was to make things go more smoothly, quickly and efficiently. I could also complain about other construction in the area probably connected with this mess, but, “enough said.”
