Project History

Environmental Document released for public involvement on October 2009Presented 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.

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.

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 trafficflow concerns.

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.

Proposed Right of Way

Environmental Impacts Existing land use is agricultural

and residential. Historic farm east of the

intersection and south of CR 400 is eligible for National Register of Historic Places.

No right-of-way will be cquired from acquired from this farm.

(35%) reduction in all accidents More than 90% reduction in fatalities

Other BenefitsOther Benefits Provides efficient traffic flow Reduces noise and air pollution Less fuel consumption Lower operation and

maintenance costs
