Cyntheanne Road Transportation Planning Study - Indianapolis ...

5.0 Project Summary
In summary, the existing Cyntheanne Road corridor is not adequate to handle an
increase in traffic due to safety, operating capacity, and connectivity issues.
Listed below are the key findings and design recommendations derived from
traffic data review, field inspections, public meeting comments, and comparison
of alternatives.
Safety: The existing roadway design has safety issues due to narrow lanes, lack
of shoulders, and lack of lane striping. To improve safety, new typical roadway
designs have been analyzed in order to include wider lanes, medians to protect
turning vehicles, and new bicycle and pedestrian pathways.
Mobility: Connecting Cyntheanne Road improves mobility by providing a
continuous north-south corridor located on the east side of Fishers. With the
addition of the Del Webb residential development, traffic will dramatically
increase. Additionally, the future commercial and residential traffic this corridor
is planned to develop will cause increased demand along this corridor. The use of
two lanes will be sufficient as an interim design; however, additional right-of-way
should be purchased so that four lanes could be constructed when new
development occurs and volumes increase.
Cost: Construction and right-of-way costs have been derived for the four
alternative routes and include two different typical sections, which involve the
use of two or four lanes of traffic. Safety and mobility were included in the
comparison and evaluated to determine if the cost of the roadway design is
justified.
Environmental: Each of the alternatives has been ranked according to the
alignment’s environmental impact. A ranking of high means that there is a
significant potential for the need to develop a full environmental impact
statement. A ranking of low to medium indicates conformance to the NEPA
regulations will be required, but impacts resulting from the construction of this
alternative can potentially be mitigated. The medium to high ranking assigned to
Alternative 4 results from concern stemming from wetlands and the unknown
soil conditions in this area near Fall Creek.
