King County Proposes Elevated Road Conversion for Snoqualmie Valley Flood Resilience
What happened
King County is seeking feedback on a proposal to convert one of two roads in Snoqualmie Valley into a trestle or elevated roadway. This measure is intended to provide reliable access to communities along SR 203 during winter flooding. The proposal follows incidents, such as the December 2025 floods, where blocked roads severely delayed emergency medical services access from Carnation to Seattle Children's Hospital.

Improving flood reliability could reduce the economic disruption and associated costs of severe weather events for communities in the Snoqualmie Valley.
