Floyd County, IndianaFloyd County Thoroughfare PlanSection 4–Alternatives Evaluation4. Edwardsville Galena RoadEdwardsville Galena Road operates at LOS C in the future no-build scenario. EdwardsvilleGalena Road is not expected to experience significant congestion issues by the year 2030.There are two main options to improve the operations for this corridor. The first optionwould be to widen the current driving lanes and construct shoulders. The second option isto reduce the number of access points. The reduction of access points is not likely to be asuitable option because all the access points are private driveways and eliminating themmay not be feasible.5. Baylor Wissman RoadBaylor Wissman Road operates at LOS B in the future no-build scenario. Baylor WissmanRoad is not expected to experience major congestion by the year 2030. To improve thesafety of the roadway, widening the travel lanes and adding shoulders could be considered..6. US 150The US 150 corridor will experience poor operations in the future no-build scenarios. Evenwith the planned two-way-left-turn-lane for the two lane portion of US 150 to the west ofBrush College Road, significant congestion and delays can be expected. As the roadwayapproaches its capacity, drivers will seek other routes through Floyd County. The roadwaysmost likely to receive traffic diverted from US 150 are shown in Figure 4.01-1 and theyinclude:• Edwardsville-Galena Road–Old Vincennes Road• Old Vincennes Road• Paoli PikeSome drivers will travel at a different time, use a different mode, or eliminate their tripaltogether. These responses to congestion will reduce motor vehicle travel demand onUS 150 until it equals the roadway’s capacity.As congestion increases, it will become increasingly difficult to access the minor streetsthat branch off of US 150 that do not have signal control. Several minor streets may requiretraffic signals to allow for access to the neighborhoods that they serve. Existing signalizedintersections will also have to be evaluated for the need of additional lanes, added phases,and possible corridor signal coordination.Improvements to the western portion of US 150 are deemed to be a priority. The volumesforecasted for the two-lane portion of US 150 west of Brush College Road are above typicaltwo-lane street capacity thresholds. Even with the addition of a center left turn lane, thevolume of traffic is still not sufficiently served. The most conventional way to fullyaccommodate these volumes would be expansion to a divided four-lane highway. Theintersections with minor roadways that will not receive signal control will be able to use themedian as a refuge. This allows the left-turn movements to be completed in two stages,requiring a gap in only one direction at a time.Prepared by Strand Associates, Inc. ® 4-2KRH:pll\S:\@SIECO\001--050\046\008\Wrd\Thoroughfare Plan\Draft 07-19-07\S4-Alternative Evaluation 07-19-07.doc\072007
