Madison BRT - RapidRide G Line: Downtown Seattle to First Hill to Madison Valley

Updated: April 5, 2021

What’s happening now?

We've reached final design on the Madison BRT - RapidRide G Line project and the Federal Transit Admistration has now allocated $59.9 million in funding to this project (which covers about 45% of the total budget). See more in our April 5, 2021 blog post.

Depending on that funding timeline, we expect construction to start in fall 2021 and to open the new G Line in 2024. 

See what the project will look like on your block!

Before construction starts, we're collecting additional information from neighbors on access needs and who to contact during construction. When we have the construction contractor on board, we'll have more to share on what to expect during construction. Feel free to contact us with questions or to meet with our project team. 

Project Overview

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.

The project will provide fast, frequent, reliable, and safe public transportation between 1st Ave and Martin Luther King Jr Way. The route will serve highly dense neighborhoods in downtown Seattle, First Hill, Capitol Hill, the Central District, and Madison Valley. It will connect people to hospitals, schools, businesses, and other destinations as well as to dozens of bus routes, the First Hill Streetcar, and ferry service at the Colman Dock Ferry Terminal.

Madison St BRT - RapidRide G Line is a partnership between the City of Seattle and King County Metro. King County Metro will operate service on Madison Street as RapidRide G Line.

SDOT and King County Metro are currently working to make RapidRide investments to multiple corridors as part of SDOT's Levy to Move Seattle Transit-Plus Multimodal Corridor Program and King County Metro's RapidRide program.

What are the benefits?

Reliability

  • Buses will come at least every 10 minutes throughout the day
  • Bus only lanes and bus priority at traffic signals reduce bus travel time (by 5 minutes from Colman Dock to Madison Valley) and improve reliability
  • All-door boarding and doors on both sides, so people can board efficiently from new center-running stations (between 9th Ave and 13th Ave)
  • ORCA readers at the stations to pay before boarding
  • Real-time bus arrival information at stations

Accessibility

  • Station platforms level with bus so no stairs to climb
  • New curb bulbs, crosswalks, sidewalks, curb ramps, and bike lanes in sections

Equity

  • Serves historically underserved neighborhoods with an affordable and reliable transportation option

Upgrades and vibrancy

  • Updated utilities and street paving
  • New art and landscaping

What will it look like?

  1. Rendering above at Central Library shows a station shelter, real time arrival info, station platform at the same level as the bus, and bus lane. 
  2. Rendering at Madison and Terry shows a center running station, pedestrian refuge (protected space in the middle of the street), center running bus lanes, new curb ramps, landscaping, station shelters, and real time arrival info. 
  3. Rendering at Madison and 12th Ave shows a center running station, new curb ramps, pedestrian refuge (protected space to wait in the middle of the street), bus lanes, landscaping, and new curb ramps. 
  4. Rendering at Madison and E John St shows a station platform level with the bus, bus only lane, new curb ramp, yellow tactile strip for people with vision impairments, station shelter, and real time arrival info.

Project features map

The map above shows key features of the project. Features include:

  • Repaving the street and changing the lane layout, including widening Madison by 1 to 2 feet in some locations
  • Building new bus platforms along the project area, including 4 center-running stations between 9th and 12th avenues
  • Placing new bus shelters and other station amenities
  • Installing new poles and relocating some overhead trolley wires to match the new street layout
  • Upgrading the streetlight network in the First Hill neighborhood
  • Installing five traffic signals (8th Ave and Spring St, 10th Ave and Madison St, 18th Ave and Madison St, 19th Ave and Union St, Harrison St and MLK) and upgrading existing signals
  • Installing detention tanks to manage stormwater runoff (Madison St between 12th and 13th avenues, 10th between Madison and Seneca streets, and E Pine St between 15th and 16th avenues)
  • Water and sewer main replacement east of Broadway
  • Building curb bulbs to shorten pedestrian crossings (Madison St at the intersections of Minor Ave N, 10th Ave, 12th Ave, Union St,  Pike St, 15th Ave, 18th Ave, 19th Ave, Denny St, John St, and 27th Ave; Spring St at the intersections of 7th, 8th, and 9th avenues)
  • Building new and upgrading many existing curb ramps
  • Landscaping throughout including tree removal and replacements and enhancements on Spring Street over I-5
  • Public art (Madison St and 14th Ave, Madison and Pike streets)
  • New bus stations and bus lanes
  • New bike connections

What to expect during construction

Construction will be disruptive. You can expect to see and hear construction activities throughout the corridor during the duration of work. Construction impacts will include:

  • Noise, dust, and vibration
  • Nighttime and weekend work, as needed
  • Traffic shifts and detours for people walking, biking, driving
  • Temporary utility shut offs
  • Temporary driveway, street, and lane closures
  • Temporary parking restrictions and permanent parking removal

Planned construction timeline

  • Spring or summer 2021: Select a contractor to build the project. After a contractor is selected, we'll know more on the following:
    • Work schedule and working days
    • Construction sequencing
    • Traffic control plans (e.g. intersection, road, and side street closures and detours)
  • Fall 2021: Anticipated construction start
  • We expect construction to take about 2.5 years to complete and the RapidRide G Line to open in 2024

Funding

This project is partially funded by the voter-approved Levy to Move Seattle, the voter-approved Sound Transit 3 (ST3) package, and state and federal grants. We are pursuing Federal Transit Administration (FTA) funding to be able to deliver this project. The project budget is about $133.4 million. This was increased due to FTA requiring additional contingency funding.  

A recent federal report determined SDOT is qualified to complete the Madison St Bus Rapid Transit (BRT) - RapidRide G Line project. This step is an important milestone toward qualifying for Federal Small Starts Grant funding, covering about 45% of the project cost. See more in our April 5, 2021 blog post.
