Rd. 19. The roadway curve, the earth bank, power p ion <br />his sightHowever, tof and roadway signs all <br />contribute to this distance problem. es he closer to the intersect the motorist gets the clearer the visibility becomes ands at a point within about <br />100fetothe p f h intersection, the sight distance opens up so that an approaching <br />spotted vehicle from the <br />west can be s d 425 feet away. At prevailing speeds, this <br />left 1 turn to o south, or <br />allows tree motorist ample time to either proceed with a 9 <br />vehicle i s close enough to present a hazard. our field crews <br />stop i f an approaching <br />have been instructed to adjust the signs in order to provide as great a sight <br />� receive this <br />distance as possible. This task should be completed by the time you r ec <br />letter. It may also be necessaryto relocate the power poles and/or grade down the <br />earth bank if either becomes a problem 4 n the future. <br />The re „ion ale for the traffic control change in the first place was, of course, to <br />convert the intersection <br />tersection into a standard "T", traffic operationwise, where only the <br />south approach to the intersection would be stopped and the right turns permitted <br />i el d sin cbntrol . Eastbound CSAH 19 traffic which previously <br />to operate under y 9 <br />was stopped now flows freely through the intersection yielding onl y' i f making a <br />right turn. A more efficient, free flowing intersection eliminating numerous, <br />9 will provide de the byproducts of conserving energy and decreas i ng <br />unnecessary stops wi yP pollution <br />and noise of l ution i n perhaps greater safety than before (after the initial <br />i n time period). Positive results have been achieved at other locations on <br />- <br />the o P e CSAH <br />county highway system where similar mi 1 a r type improvements have been made; i • • <br />the co y 9 y y <br />19 and Country Club Corner in Shorewood.
