Eastside Rail Corridor Trail Master Plan

King County, WA

The King County Eastside Rail Corridor (ERC) Master Plan Project is the first phase in the development of a 17-mile regional trail along former rail line. TDG worked within a larger interdisciplinary team, to evaluate the feasibility of construction regional trail connections at five locations: Renton, I-90, Bellevue, 520, and Woodinville. This included conducting field assessments, analyzing and evaluating connection alternatives, developing planning-level cost estimates, completing a detailed demand analysis, and developing corridor-specific design guidelines. TDG engaged local jurisdictions and the Washington State Department of Transportation on developing and evaluations potential connections.
