Blaine Street Stairs, Public outdoor staircase in Capitol Hill, Seattle, United States.

The Blaine Street Stairs are an outdoor staircase of 293 steps in Seattle's Capitol Hill neighborhood, running parallel to the Howe Street Stairs and adjacent to the Streissguth Gardens. The flight links streets at different elevations on the hill.

Built in 1911, these stairs are part of Seattle's network of over 650 public staircases designed to address the city's steep topography. This infrastructure was created to make the hilly terrain more accessible for people walking through the neighborhood.

The stairs run beside Streissguth Gardens, creating a natural passage that connects residential neighborhoods while serving as a popular training spot for locals. People use this route regularly to move through the community and get a workout at the same time.

The staircase has 293 steps, so plan for a sustained climb rather than a short flight. It runs parallel to the Howe Street Stairs, which offers a second route up the same slope if you want to vary the ascent or descent. Sturdy shoes help on the concrete treads.

A section of the stairs passes beneath Interstate 5, creating an unusual underground passage through the I-5 Colonnade beneath the elevated highway. This hidden area under the highway surprises many visitors who discover this quirky architectural feature.
