Location E: Silver Fir Area Area Limits SR 906: Tanner Way to Summit Central Jurisdiction WSDOT Land Use Context Access to downhill skiing, snow tubing, mountain bike park, and vacation rentals Speed Limit SR 906: 35 mph AADT Not available Proposed Countermeasures A series of countermeasures were selected for the Silver Fir area to address both collision-related and non-collision-related concerns, as illustrated in Figure 30. Items in bold are FHWA Proven Safety Countermeasures. Cost Estimates Approximate planning-level costs for each countermeasure are outlined below: Table 7. Location E - Cost Estimates of Proposed Countermeasures Countermeasure Application Crash reduction factor * Cost level† Shared Use Path Corridor Not available $$$ Speed limit reduction Corridor Not available $ Access Management Intersection Not available $$ Crosswalk pavement markings Crossing 40%$ Pedestrian lighting Crossing 42%$$ RRFB Crossing 47%$$ Source: SCJ, 2025. It is important to note that due to snow-plow activity within the Snoqualmie Pass area, recessed plastic pavement markings are recommended for channelization. Sufficient budget must be allocated for renewing pavement markings for the proposed solutions to be effective. * CRFs are approximated based on the data provided by the FHWA Proven Safety Countermeasures. † Costs are based on a preliminary engineer’s estimate of magnitude. Collision History Between 2014 and 2023, there were five reported collisions in this priority area. Of these five collisions, three occurred when a vehicle was traveling straight ahead, and two were parking related. One collision resulted in a possible or minor injury, and all were vehicle-only collisions. Four collisions occurred on an icy roadway surface. Two collisions were single-vehicle crashes where drivers collided into a snowbank. Non-Collision Concerns Additional concerns were identified in this area through public comments, stakeholder feedback, and observation by the County and consultants. Concerns include: High speeds: Curvature of roadway limits stopping sight distance at higher speeds. Pedestrian Circulation: Lack of pedestrian access throughout corridor. Pedestrian crossing at Tanner Way: Private parking lot is separated from the Silver Fir Lodge by SR 906, resulting in frequent crossings of the highway for lift access for skiing and mountain biking. Crosswalk striping is not visible. Crossing signs are not up to current standards. 20% Possible or minor injury collision1 5 Reported Collisions Of the 5 collisions: 3 Involved a vehicle going straight ahead.
