Throughout the mid-1880s, the Northern Pacific Railway, the parent of Northern Pacific Coal Company, pushed from the east to reach Puget Sound across the Cascade Mountains. The Northern Pacific began building across Stampede Pass just west of Roslyn, approaching from Wallula in the east and Tacoma in the west. A 77-mile (124-km) gap remained in 1886. In January of that year, Nelson Bennett was given a contract to construct a 9,850 foot (3,002 m) tunnel under Stampede Pass, completing it in 1888. Roslyn, which lies on the route to Stampede Pass, provided the coal for the railway construction work as well as the continuing railroad operations.
