A roundabout is a circular intersection designed to maximize safety, minimize delay and decrease fuel consumption. There are no traffic lights or stop signs at a roundabout.
New Roundabout - Cumberland Street and Water Street
A new roundabout is being constructed at the intersection of Cumberland Street and Water Street as part of a major infrastructure upgrade. Cumberland Street is fully closed from McVicar Street to Howe Street. The closure will extend south to Villa Street and eventually to Tupper Street as work progresses, and is expected to remain in place until the fall. Stay tuned for updates and roundabout education opportunities.

The ins and outs of roundabouts
See below for information on how roundabouts work!
For even more information, we recommend the resources made available by the Ontario's Ministry of Transportation (MTO), including a downloadable roundabout PDF.
Roundabouts are safe and easy to use. Here is a quick guide:
- Reduce speed and approach the roundabout
- As you prepare to enter, make sure to yield to vehicles already in roundabout
- Wait for space and then enter roundabout safely
- Continue through your exit while checking for cyclists and pedestrians
Benefits of roundabouts
Vehicle safety |
|
All vehicles travel in the same direction, never crossing paths. This reduces the severity of vehicle collisions. Slower speeds also give drivers more time to react and make decisions. |
Pedestrian safety |
|
A pedestrian crossover will be installed and the crossing will be shorter, reducing potential vehicle conflicts. |
Pollution reduction |
|
Since there is a significant reduction in vehicle idling, less gas is being burned and exhausted into the atmosphere. This fits well with the Thunder Bay Net-Zero Strategy. |
Reduced fuel consumption |
|
In addition to emissions reduction, fuel consumption is reduced. |
Speed reduction |
|
Roundabouts have the effect of calming traffic and speed in neighbourhoods. |
Improved traffic flow |
|
Roundabouts provide an increase in traffic capacity. |
Lower life-cycle costs |
|
Operation and maintenance costs are lower compared to traffic signals. |
