Location D: Summit Central Area Area Limits SR 906: Summit Central to Yellowstone Road Jurisdiction WSDOT Land Use Context Summit Central, downhill skiing Speed Limit SR 906: 35 mph AADT Not available Proposed Countermeasures A series of countermeasures were selected for the Summit Central area to address both collision-related and non-collision-related concerns, as illustrated in Figure 29. Items in bold are FHWA Proven Safety Countermeasures. Cost Estimates Approximate planning-level costs for each countermeasure are outlined below: Table 6. Location D - Cost Estimates of Proposed Countermeasures Countermeasure Application Crash reduction factor * Cost level† Shared Use Path Corridor Not available $$$ Roadway Reconfiguration Corridor Not available $$$$$ Speed Limit Reduction Corridor Not available $ Advance warning signs and/or pavement markings for crosswalk Corridor 42%$$ Pedestrian Hybrid Beacon Crossing 55%$$ Crosswalk Lighting Crossing 40%$$ Crosswalk Lighting Crossing 40%$$ 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 seven reported collisions in and adjacent to this priority area, including two KSI collisions. Of these seven collisions, six collisions involved a vehicle going straight ahead. Two collisions involved a parked vehicle. All were vehicle-only collisions. Non-Collision Concerns Additional concerns were identified in this area through public comments, stakeholder feedback, and observation by the County and consultants. Concerns include: Pedestrians crossing to Summit Central because parking area is separated from Summit Central by SR 906, resulting in frequent crossings of the highway to access the ski area. Existing crosswalk beacon is not effective because it lacks a pedestrian push button on the west side of the highway and lacks advanced warning for drivers. Congestion along SR 906 due to conflicts between vehicles parked along roadway and vehicles in travel lane, pedestrians in roadway to access ski area, and a continuous flow of pedestrian crossing causing traffic backups. High speeds along SR 906 during summer when congestion is reduced and roadways are clear. 29% 6 Involved a vehicle going straight ahead. Collisions 2 Involved a parked vehicle.
