TH [0 is atready congested-and it is likely that this major highway wilt become <br /> even more congested in the future. By 2007, the intersection of TH 10 m'~d <br /> Armstrong should be redesigned to handle the additional traffic with a si,x:-lane <br /> highway and dual left turn fanes eastbound and triple left turn-lanes southbound. <br /> It is proposed that a new !nterchange wiil be built, at TH 10 with the realignment <br /> of Armstrong Boulevard. In 20 [ 7, the traffic can be handled with a single-point <br /> interchange desi'gm. By 2030, there is likely to be a new river crossing that will <br /> connect to this interchange. Projections 'tbr fl:tis crossing indicate that 45% o~' the <br /> traffic now using TH 10 to the east of Armstrong w/l[ now use the river crossing <br /> to head sottth and east; With these projections, a single-point inte~:change will not <br /> operate effic3ently at this location, specifically due to the redistribution of trips as <br /> a consequence of the rivet' crossing. To assure LOS D or better operations, a <br />· system-to-system type interchange that allows l'br fi'ce movements no~ to west <br />and east to south would be vet? imp0t'tant. Tl'te other left turn movements would <br />'also greatly benefit as free mov4ments. <br /> <br />-464- <br /> <br /> page 24 oJ'24 <br />Prepared by: <br />Bolton & ;¥fenJ¢ ]nc <br /> <br /> <br />
