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.
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 traffic
flow 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.
