About the Event

This three-day class focuses on preliminary layout geometric design. Participants will draft preliminary layouts and demonstrate project-oriented geometric design concepts and operational and safety performance outcomes. Participants will also increase awareness of the layout submittal process, project documentation and guidance documents, MnDOT policies, and the Geometric Design Support Unit’s review and approval process. Class exercises will include interchange, RCUT, roundabout, downtown recon, and working within constraints.

At the class, participants will use design equations, charts, and resource manuals. Participants will sketch preliminary layouts and geometric design applications for highway preservation projects and for new highway construction projects. The curriculum features the following case examples:

  • TH38 downtown reconstruction in Big Fork
  • TH52 interchange in Hader
  • Hwy. 371 RCUT corridor in Brainerd
  • TH194 roundabout in Saginaw
  • Working within constraints, Anoka Hwy. 10 at Thurston
