15th St. & Reed Market Rd.

Bend, OR

MTJ Roundabout Engineering’s Mark Johnson, P.E. provided the peer review analysis, horizontal design, and signing and marking recommendations for this project in Bend, Oregon working as technical area expert to Parametrix, Inc. This project included design alternative recommendations for addressing potential operational issues associated with the nearby railroad located 1150’ to the west of the roundabout (not shown).

Recommendations to maintain traffic operations during train events and support emergency response included:

  • Additional entry and circulating lanes
  • Advance warning signs that activate when train is present; “Train Ahead”
  • Restrictive signs that activate when train is present; “Do Not Block Intersection” and
  • Traffic signal at entry legs restricting entry to roundabout during crossing events.
