Coffman and Brand Roads Roundabout

Dublin, OH

MTJ Roundabout Engineering provided capacity analysis and design alternatives for this intersection. Some of the main requirements of the project included interim and ultimate designs, approach speed constraints, ROW constraints, and OSOW considerations.

MTJ prepared two design alternatives, each with differing impacts. Both alternatives were designed to achieve the necessary capacity and LOS for the proposed project.
The alternative that was chosen has an EB auxiliary RT lane that is separated from the through lane with a median island.

Highlights

  • High-speed/transitional application
  • Accommodates large truck movements
  • Compact pedestrian/freight design
