way needed, a median with a concrete barrier should be considered. This will provide the "safety aspects of a median, without the added right of way width (and associated costs) required for a depressed grass median." Simple diamond interchanges, for the sake of the study and to estimate the expected cost, was used. No interchange decisions have been made in reality. This would require of additional right of way compared to alternate 3. The number of relocations total approximately 95 residences and 1 business, and would require the closure or relocation of numerous entrances. Alternate 4 meets all project goals but at a much higher cost than alternate 3. The public perception of this alternate was not as favorable as it was to alternate 3 due to higher costs, the large number of relocations, and limited access. "The potential impacts to the area, including relocations, cultural-historic, archaeological and environmental sites, are much higher than Alternate 3." Cost: $33,860,000 (design), $19,410,000 (right of way acquisition), $2,140,000 (utilities), $423,252.000 (construction): $478,662,000 (TOTAL) Two median types were considered: a concrete barrier wall and a depressed grass median. Mountable medians in rural areas are not recommended. With each median type option, there would be travel lanes and shoulders. The depressed grass median would be 40 to , separating the two opposing traffic flows effectively. Due to the high speed of travel, access control with a minimum of is recommended for the limited access alternate. Also under consideration is using the existing alignment of the AA Highway as the eastward continuation of Interstate 74 from Cincinnati to Grayson, where it would connect with Interstate 64. This would necessitate adoption of Alternate Four described above. References External links KentuckyRoads.com KY 9 0009 0009
