J -' - - '. ~ DETAILED EVALUATION OF ALTERNATIVES - , - The alternatives that passed through the initial screening of alternatives were evaluated in more detail. The conclusions reached in the initial screening were: - , - 0 Highway 96 needs two through lanes in each direction, it should have 8 foot shoulders, ~ 0 , 0 left-turn lanes should be provided where left-turns are permitted, - 0 Highway 96 should be an urban section with curb and gutter. - I Median Alternatives - ~ ~- I The only remaining cross-section issue following the initial screening of alternatives is the width of the median area on Highway 96. There are four potential alternatives for the median area. - - 0 Wide Median - The wide median would be 30 feet wide and would be of sufficient , -- width to allow double-left turn lanes where needed, . ~ I 0 Narrow Median - The narrow median would be 18 feet wide and would provide for - single left-turn lanes where left-turns are permitted. ~, _____.c I- 0 Two-way Center Left-Tum Lane - The two-way center.left-turn lane could be 14 feet - wide and would allow for left,turns in both directions. - I 0 No Median - In sections of Highway 96 where there is no access it may be possIble -,- to get rid of the median area. -. , The preferred median alternative can be different for different segments of the corridor. In order to ----- facilitate the evaluation, the corridor was divided into the following segments for evaluation. - , Old Highway 8 to Highway 10 - 0 0 Highway 10 to Lexington A venue - , 0 Lexington Avenue to Hodgson Road -'-= Hodgson Road to Rice Street ..',. 0 0 Rice Street to McMenemy - I 0 McMenemy to Centerville Road - -- A matrix was developed for each segment indicating the key points relative to nine different I evaluation criteria, The matrix for each segment is attached at the end of this memorandum. - -- In locations where there is plenty of right-of-way, where access is nll'f1in issue, and where there is , little or no impact to adjacent land uses or wetlands the wide median would be the ideal alternative - because it provides the highest level of safety, it provides the greatest flexibility for enhancements, - .- - it provides the opportunity to add double left-turn lanes at selected locations without further widening, and it would provide a consistent cross-section throughout the corridor.
