[citation needed] The trestle carried a single track of a former Northern Pacific branch line over a valley that used to be an extension of Lake Washington.

Before the abandonment of the rail line by BNSF, freight trains ran six days a week, including those carrying Boeing's aircraft fuselages to its assembly plant in Renton.

[1] The trestle was originally completed in 1904[2] as part of the Northern Pacific Railway's Lake Washington Belt Line from Black River Junction (south of Seattle) to Woodinville.

[1] In 1973, a road, the Lake Hills Connector, was cut through the trestle, replacing a short section with concrete piers and steel deck girders.

Construction began in 2024 and is scheduled to be completed in 2026; it is estimated to cost $37 million with funding provided by a county levy, state carbon credits, and grants from Amazon and Kaiser Permanente.
