67 Street/Johnstone Drive Corridor Improvements
Large vehicles using the roundabout
The roundabout can accommodate large vehicles, including trucks with trailers.
A truck apron in the centre of the roundabout serves as an overrun area for large vehicles that require more turning area. The dedicated right turn lanes will also help large vehicles navigate the roundabout. For more information and tips, see Large vehicles and modern roundabouts (pdf)
What is a modern roundabout?
A modern roundabout is a circular intersection where drivers travel in a counterclockwise direction around a central island. Drivers enter the roundabout by yielding to traffic already in the roundabout. No lane changes are needed as drivers choose their lane before entering the roundabout and exit at their street.
There are several safety and operational benefits for roundabouts versus signalized intersections including:
- Up to 80 per cent fewer injury and fatal accidents
- Slower speeds resulting in a lower risk of serious vehicle collisions
- Improved traffic flow and fewer delays
- Accommodates higher traffic volumes
