lntersection lmprovement <br />Landscape or hardscape <br />buffer <br />Intersection of I-90 EB Off- <br />ramp SYellowstone Road <br />As a long-term solution, restrict left-turn <br />movements from the EB l-90 off-ramp to reduce <br />the length of backups on the off-ramp extending <br />to mainline l-90. Removing cars waiting to take <br />a left-turn could allow drivers to turn right in <br />less time from the EB off ramp and use the <br />roundabout at SR 906 & Yellowstone Road to <br />travel east on Yellowstone Road. <br />lntersestion lmprovement <br />,li::lti: <br />Intersection of SR 906 I Yellowstone Road <br />Construct a roundabout as a long-term solution to <br />illuminate confusion at the existing tee-intersection and <br />provide a continuous flow of traffic to reduce congestion. <br />lntersection lmprovement <br />lntersection lmprovement <br />Intersection of SR 906 ft <br />Yellowstone Road <br />lmplement a dedicated left-turn lane on SR 906 <br />5B toward the l-90 EB and WB on-ramps to <br />address congestion at peak times. <br />lmplement a dedicated right-turn lane on SR <br />906 NB toward the l-90 EB and WB on-ramps <br />to address congestion at peak times. <br />lnstall lighting to make the intersection <br />more visible at night. For a popular winter <br />destination, ice on the roadway can limit <br />stopping sight distances and make approaching <br />the intersection dangerous. Lighting provides <br />advanced warning of a congested area as well <br />as makes the intersection safer for drivers and <br />pedestrians. <br />Reconfigure the roadway to reduce the <br />intersection width and decrease sign distance <br />from roadway. <br />Reduce the shoulder outside of the minimum <br />pavement area to discourage parking and <br />provide additional snow storage. Apply low- <br />cost countermeasures at stop-controlled <br />intersections. Treatments could include: <br />. Stop bars at existing stop sign locations. <br />. Advanced warning signs <br />("Stop Ahead'i W3-1). <br />. Oversized stop signs. <br />. $noqualmie Pass Comprehensive Safety Plan I Kittitas County <br />90 <br />c Figure 28.
