Milestones and Schedule

Madison Street Corridor Bus Rapid Transit

Updated April 16, 2015

Upcoming Community Events:

May 6th: SDOT will host an Open House on May 6th from 5 -7 PM at the Seattle Academy of Arts and Sciences Middle School, 1432 15th Avenue. The Madison BRT project is an opportunity to provide neighborhoods with a faster, more reliable transit connection to key destinations, enhance walking conditions and the streetscape along Madison, and identify an alternate bike facility to be built as part of the project.

Please join your neighbors to review design options, discuss benefits and trade-offs, and provide your input on priority elements for the project. SDOT would like your input on:

  • BRT design options, routing, terminals, and station locations
  • Priorities for transit service and capital investments
  • Design concepts for a Central Area protected bike lane

Recent Community Events:

January 22nd: The Madison Corridor Bus Rapid Transit (BRT) Study hosted an online survey. The survey contained questions on important transit connections, routing options, station locations, and an alternate bike facility. The Survey Summary Report is available here. A copy of the survey is available here.

Project Overview

Click on the map above to see the Madison Corridor section of the Transit Master Plan.

The Seattle Transit Master Plan (2012) identifies Madison Street between Colman Dock Ferry Terminal in downtown Seattle and 23rd Avenue E as a future high-capacity transit bus rapid transit (BRT) corridor. The proposed transit investment is based on an evaluation of the Madison Street Corridor’s potential to generate ridership, supported by its land use and demographic characteristics, and a screening of potential transit modes, considering factors, such as passenger carrying capacity and constructability. SDOT and King County Metro are working closely to coordinate planning for the project.

Madison Street BRT service will be fast, reliable and frequent. It will serve densely developed neighborhoods in First Hill, the Central Area, and downtown Seattle, connecting dozens of bus routes, the First Hill Streetcar, and ferry service at the Colman Dock Ferry Terminal.

Madison Street BRT will use new state-of-the-art electric trolley buses (ETBs) that produce zero emissions and are extremely quiet. Surface rail transit is not an option for this corridor due to the steep east-west street grades.

Project Definition Study

The Madison Street corridor is an opportunity for Seattle to design and implement, in phases, state-of-the-art bus rapid transit (BRT) improvements. The 2.1-mile corridor runs from Colman Dock to 23rd Avenue and will improve access to ferries, Third Avenue transit, First Hill medical institutions and housing, Seattle University, the Central district, Link light rail, and the First Hill Streetcar.

In June 2014, the City will begin studying this BRT corridor. The study will evaluate roadway channelization options, station locations and features, bicycle and pedestrian facilities, and streetscape improvements for the Madison corridor. The study will engage transit agencies, stakeholder, and the broader community to discuss options and tradeoffs. It will also evaluate implementation options, such as phased speed and reliability improvements and funding opportunities.

The Seattle Transit Master Plan identifies a planning-level total capital cost estimate of $87 million. The Seattle City Council identified $1 million in the City’s 2013/2014 budget for a project definition study of the Madison Street corridor. This effort will result in a refined project cost estimate.
