Madison Street Bus Rapid Transit

What's happening now?

This summer and fall, the locations below are hosting an information kiosk about the project:

1700 23rd Ave

The Polyclinic
904 7th Ave

Also this summer, you may have seen small work crews on the corridor as we continue utility location and soil testing work.

Did you know? Madison Street BRT will become RapidRide G Line when service begins.

Overview design image


Overview map image The Madison Street BRT Route has been shaped by public input.

The Seattle Transit Master Plan (2012) identified Madison St between the Colman Dock Ferry Terminal in downtown Seattle and 23rd Ave E as a future high-capacity, bus rapid transit (BRT) corridor.

Madison Street Bus Rapid Transit (BRT) will provide fast, frequent, reliable, and safe public transportation between 1st Ave in downtown Seattle and Martin Luther King Jr Way. The route will serve densely developed neighborhoods in downtown Seattle, First Hill, Capitol Hill, the Central Area, and Madison Valley. It will connect to dozens of bus routes, the First Hill Streetcar, and ferry service at the Colman Dock Ferry Terminal.

Madison Street BRT is the first of 7 new RapidRide lines in Seattle. When service starts in late 2019, King County Metro will operate Madison Street BRT as RapidRide Line G.

RapidRide in Seattle is a combination of service improvements, capital investments, and design treatments that build on the success of existing RapidRide service. Madison Street BRT is also making additional station improvements.

We 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.

Levy to Move Seattle
Madison Street BRT is partially funded by the voter-approved Levy to Move Seattle and the voter-approved Sound Transit 3 (ST3) package. We are pursuing other funding sources for final design and construction, particularly Federal Transit Administration funding. Estimated project cost is $120 million.
