The most sig~fi06nt accomplishment of this alignment is the creation of 153rd Avenue as an east/west cro~;tO~Wn arterial. The alignment will require the construction of 0.65 miles of roadway. Initl~llyqth~s roadway will servme a minimum of 5:~0 vehmles per day. Thxs projection is based on an analysis of the traffic using the east/west streets immediately north of the proposed roadway. The ifa~t~ that convenient crosstown access would be available will generate additional trips. Without !th~ benefit of a relatively costly origin/destination engineering study, however, it is not possible ti! qfi~intify this amount of additional traffic. The alignment will reduce the travel between the t~i° ~ints it connects by 0.4 miles and will eliminate four tums currently being made by traffic wish ing I~o traverse these two points. Within a 20 year design period, traffic counts on this segment iol!r~dway are anticipated to triple. The construofi, ,n Of this roadway will reduce traffic on 156th Avenue from 468 vehicles per day to approximately 74 yehicles per day. Likewise, the traffic on 158th Avenue can be expected to decrease by aP ~r0Ximately 150 vehicles per day. The total proj~ti¢ost is anticipated to be $600,000 with about $400,000 being anticipated in construction ~ost~i Major construction costs associated with this alignment include grading, paving, curb arid ~tter, wetland construction and impact mitigation. Alternative 1: i, Connect 155th Avenue with 154th Lane. This altemafiv~ W~ proposed by a resident at the September 24 meeting. The proposed alignment is illustrated ~ tl~4~ attachment entitled Alternate 2 and entails the construction of 0.5 miles of roadway. Tl~i~alig~nment would provide direct connection of the eastern segment of 153rd Avenue with Arrnstron~g Btbulevard. Truck traffic wishing to continue westward would need to turn left onto southbo~d?,~krmstrong Boulevard for 1100 feet, turn right and then continue on 153rd Avenue west~ ~ard. i Acceleration and deceleration charts will verify that even passenger vehicles making this r~anet~ver will not reach the posted speed of Armstrong Boulevard. In fact, a passenger veh~zlei~ill only reach top speed of approximately 35 miles per hour which means that these vehicles Will ibc traveling this 1100 foot distance at speeds between 20 to 40 miles per hour slower that At: ~s~ng Boulevard traffic. Truck traffic making this maneuver will accelerate and decelerate eveI sl0~Wer and present even more of a safety hazard. To avoid this hazard, it is likely that passenger ve&~' ,!icles wishing to continue westward beyond Armstrong Boulevard will very likely continu ~Ohg 154th Lane. This would also eliminate one turn over the aforementioned MSA route wi iclxltt'ucks must follow. Essentially, 154th Lane and Okapi Street would function as a portion of ti:. ~stown arterial. This is objectionable from the standpoint that 39 single family residential iot{ aild one neighborhood park front on this street which was never anticipated to function as an ~trt~al street. As a sub-alteniatiV~, it may be possible to offset 155th Avenue from 154th Lane a distance of 150 feet by allowi~ fS~th Avenue to follow the section line. Although such an offset intersection may serve to deter [he(tlse of 154th Lane as a continuation of the arterial street by passenger vehicles, those vehicle~ which will continue making the cross street maneuver will do so at a greatly increased hazard, [ Such intersection offsets are considered poor from a traffic engineering standpoint and[:are Strongly discouraged. As with Altema,~ te ][,it is expected that this link would initially service a minimum of 550 vehicles per day and that ait~tional traffic could likely be expected due to the convenience of this link being available for t/~vol~ If this link were constructed, it would service the northwestern section of the City better th~ Ai~ernate 1 as it would eliminate two tums for travelers having destinations in the eastern portio~g' of [the City. In addition, Whispering Pines and adjacent subdivisions would have more direct acd, esg !o the crosstown arterial.
