Seattle’s Madison Street Bus Rapid Transit Conceptual Design

Madison Street, connecting some of Seattle’s fastest-growing mixed-use neighborhoods to its Central Business District, was identified through the Nelson\Nygaard-led Seattle Transit Master Plan as a priority corridor for the development of high capacity bus rapid transit.

Nelson\Nygaard led a multidisciplinary effort with Seattle Department of Transportation to develop a 10% design for the Puget Sound region’s first full-featured Bus Rapid Transit line. Challenges included highly constrained right-of-way, a series of irregularly configured, complicated intersections, and complex existing bus and rail service connectivity. The study is both multidisciplinary and multimodal, with urban design and bicycle route design components.

Following extensive community engagement and a technical evaluation of a range of capital and service alternatives, we developed a Locally Preferred Alternative. In early 2016, the Seattle City Council adopted the Locally Preferred Alternative and the FTA accepted the project into Small Starts Project Development.
