Project History Environmental Document released for public involvement on October 2009 • Presented as a Corridor project consisting of road rehabilitation with bridge rehab/replacements on US 31 from US 50 to CR 50 in Jackson and Bartholomew Counties. • INDOT identified areas to address as independent projects.

  4. Project History continued • The intersection at US 31 and CR 400 was identified an important improvement along the corridor and was identified as one of those independent projects. • Initiated an Additional Information (AI) to determine if any additional impacts as a result of the new project design. • Update and inform the public of the design change.

  5. Project Purpose & Need The Purpose of the project is to provide an intersection with improved safety and improved traffic flow. The Need for the project is due to safety and traffic flow concerns.

  6. What is a Roundabout? • A roundabout is a circular intersection in which traffic enters or exits only through right turns and proceeds in a counter-clockwise direction. • When approaching a roundabout – Slow Down - incoming traffic always yields to the circulating traffic.

  7. Proposed Right of Way

  12. Provides efficient traffic flow Reduces noise and air pollution Less fuel consumption Lower operation and maintenance costs Other Benefits

  13. Proposed • Single lane roundabout • 18’ Circulatory travel lane • 10’ Concrete truck apron • 95’ Green center island • Curb and gutter • 15 mph Speed

  14. Proposed • Approaches • 12’ travel lanes • 17’ entry width • Outside curb and gutter • Concrete splitter islands • Visual queue • Separates entering and exiting vehicles • Aligns driver for correct entry • Deters wrong way movements
