Two-Lanes to Single Lane Roundabout

• Traffic on Highway 212 and Morningside Avenue will merge from two lanes into a single lane when approaching the roundabout. Some examples of this type of approach exist in other places throughout the state, including:
  • Diffley Road and Daniel Drive in Eagan
  • Diffley Road and Braddock Trail in Eagan
  • East 7th Street and South Grove Street in Blue Earth
• MnDOT is designing a single lane roundabout vs. a multilane roundabout because:
  • A single lane roundabout appropriately accommodates the amount of traffic at this intersection now and into the future
  • It is designed with a mountable curb to accommodate large vehicles and trucks
  • Single lane roundabouts are more freight friendly and have less crashes compared to multilane roundabouts
• Single lane roundabouts are more pedestrian friendly as they reduce the crossing distance that pedestrians have to make
