Floyd County, IndianaFloyd County Thoroughfare PlanSection 4–Alternatives EvaluationFigure 4.01-15 Summary of Projects in the US 150 Study Area2. State Route 62/64The first alternative explored for capacity expansion in the SR 62/64 study area was theaddition of lanes to most of the corridor, and the addition of more left-turn lanes at theinterchange with I-64. However, because of the large volume of traffic, this alternativeexperienced poor operations at the interchange with long delays and queues. Because thismore traditional expansion could not adequately accommodate the increased traffic levels,two more alternatives were explored that require significant reconstruction of theinterchange with I-64 and the surrounding roads. The second alternative explored wasconverting the interchange to include a loop ramp in the southwest quadrant that wouldreplace the eastbound I-64 ramps that are in the existing interchange. The final alternativeconverted the I-64 interchange to a Single Point Urban Interchange (SPUI). Each of thealternatives involved the addition of thru lanes on most of SR 62/64 near the interchangeand the signalization of four additional intersections. A summary of the improvementsrecommended for the SR 62/64 SPUI Alternative is shown in Figure 4.01-37. Theimprovements suggested for each of the three alternatives are listed below.Prepared by Strand Associates, Inc. ® 4-19KRH:pll\S:\@SIECO\001--050\046\008\Wrd\Thoroughfare Plan\Draft 07-19-07\S4-Alternative Evaluation 07-19-07.doc\072007

Diamond Interchange Expansion AlternativeThis alternative does not involve the reconstruction of the interstate bridges.Because of this, SR 62/64 is limited to six lanes under the bridge. The proposedchanges to increase the capacity of the diamond interchange are shown inFigure 4.01-16.Figure 4.01-16Diamond Interchange ExpansionPrepared by Strand Associates, Inc. ® 4-20KRH:pll\S:\@SIECO\001--050\046\008\Wrd\Thoroughfare Plan\Draft 07-19-07\S4-Alternative Evaluation 07-19-07.doc\072007
