Delridge Way SW was identified as one of seven routes in Seattle’s RapidRide Expansion network. In 2021 partnership with King County, this project upgraded King County Metro Route 120 to RapidRide H Line between the West Seattle Bridge and south City of Seattle limits and added features to improve transit speed and reliability.
