Kittitas County I Snoqualmie Pass Comprehensive Safety Plan 36 <br />FEBRUARY <br />Analysis of February volumes provided a baseline <br />for winter conditions during peak tourism season. <br />Figure 21 presents February 2025 weekend peak <br />hour approach volumes at intersections. Across <br />both weekdays and weekends, the intersections <br />with the highest peak-hour volumes were the <br />intersection of Exit 521-9O Eastbound Off-Ramp <br />& SR 906 (Location 1), the intersection of SR 906 <br />& Hyak Drive E (Location 8), and the intersection <br />of Exit 541-90 WB Ramp & Lake Mardee Road <br />(Location 9). <br />Ttrbe counters cannotbe used in snowy <br />conditions due to interference from <br />snowplows, so speed and midblock <br />volume datawere not collected in <br />February. However, TMCs were still used <br />during the winter to assess intersection- <br />level conditions during the snowy season <br />and field observations were collected on <br />NewYear's Eve and NewYear's Day. <br />,/ <br />// <br />ffi <br />3 <br />5 <br />@ <br />+,o <br />'o,"q <br />I <br />Avo2 <br />o <br />o <br />--1 <br />o= <br />a. <br />J- <br />-(a <br />& <br />r& <br />.u.o. <br />-&U <br />a <br />o^ .-Qe?6\rn\o <br />@ <br />lanner <br />V"laY <br />I lo <br />o{K <br />$1't(\, Jton Horr" TrJ <br />Figure 27.
