New Roundabout to be installed at Highway 2A & 68 Street south of Olds

November 20, 2020

The Town of Olds is pleased to announce it has been successful in receiving a $3,000,000.00 Strategic Transportation Infrastructure Program grant from the Alberta Government. This is cost-shared funding 50 per cent provincial/50 per cent municipal. A new roundabout intersection will be installed on Highway 2A to provide secondary access into the Southeast Industrial Park, as well as to allow for smoother traffic flow into town.
The Town has focused on safety and a roundabout in this location will reduce traffic volumes at both 54 Street and 57 Street intersections, and provide direct access to the south east industrial lands allowing for additional future development.
A Traffic Impact Assessment (TIA) was completed in 2017 that analyzed the SE Industrial Park and nearby intersections on 2A. This TIA shows that signalization is not required for other intersections such as 54 & 57 Street in the foreseeable future, however, requires that this roundabout be constructed to allow for future growth in this area of town.
Alberta Transportation requires that municipalities construct roundabouts or traffic circles as priority unless it is not possible for reasons such as land constraints. A feasibility study was completed on 68 Street and it was determined a roundabout is the best option.
What is the difference between a roundabout and a traffic circle?
Roundabouts are generally smaller in diameter (60-65 meters in diameter) and have more curves leading up to the roundabout forcing traffic to operate at lower speeds - about 30 km per hour.
Traffic Circles are much larger in diameter (100 meters or larger) and typically do not have the additional curves leading up to the circle thus allowing for speeds up to 50 km per hour.
Please note: the Town is not constructing traffic circles such as the ones in the town of Sundre, as they are a pilot program study to improve traffic flows and reduce collisions without the need to acquire additional land around the intersection.
Below is an example of a roundabout constructed in the town of Sylvan Lake. Notice the curves prior to entering the roundabout.
