State Hwy. 284 & 15th St.

Waconia, MN

MTJ Roundabout Engineering provided capacity analysis, final horizontal geometrics, and signing and pavement markings for this project.

Recommendations included a wider entry width and short flare, which provide the following improvements:

  • Ample capacity for predicted traffic volume and excess capacity if traffic projections are realized sooner
  • ‘Balanced design’ from a capacity perspective

Additionally, wider entries for north- and south-bound have the added benefit of providing extra width for large trucks and the wide or long permitted load that may need to use this facility.


  • Interim/ultimate design
  • Ease of future expansion
  • Large truck/freight accommodations
