Traffic Control at Downtown Plaza Intersection
Traffic control at the Downtown Plaza intersection is just one component of the project to improve safety on Lake Avenue/Blue Earth Avenue. The road will be reduced from four to three lanes, which will:
- Improve conditions for turning traffic
- Slow vehicle speeds along the corridor
- Reduce the number of vehicle lanes that pedestrians must cross
- Allow wider sidewalk/trail on the west/south side of the corridor to improve the bicyclist and pedestrian experience.
The ultimate goal for the Downtown Plaza intersection is to provide a safe intersection for vehicles, pedestrians, and bicyclists. Below is a table that compares the different traffic control options along with their impact on safety, delay, and project cost.

How does a semi-truck or other large vehicle use a roundabout?
Many roundabouts are designed to accommodate large trucks. The videos below show a roundabout with a center island and medians designed to provide extra space for vehicles that need to make wide turns. Watch the videos below to see how a semi-truck makes both a left and right turn in a single-lane roundabout.
