    Transportation equity for underserved populations.

Using a road to enhance livability. South 154th is a central segment of a proposed regional trail that will connect Lake Washington to Puget Sound. However, walking, cycling, and public transportation were not easy to do in this urban community. The City of SeaTac wanted to support a range of travel choices that would create a broad range of higher density land uses that are not dependent on automobiles. And in the process, improve safety and flow on this primary east-west frontage road for the Port of Seattle’s air cargo activities and protect the natural environment.

Reid Middleton’s design widened the existing roadway to accommodate a center left-turn lane, created bike lanes, curb and gutter, sidewalk, storm drainage, detention and water quality, and undergrounding of the overhead utilities.
