The G Line is a future RapidRide bus service in Seattle, Washington, operated by King County Metro on Madison Street between Downtown Seattle and Madison Valley. The line is expected to enter service in 2021.[1]


The G Line will travel on Madison Street between Downtown Seattle and Madison Valley, an approximately 2.1-mile-long (3.4 km) route.[2]

The route begins near Colman Dock, the city's ferry terminal, at a station on 1st Avenue shared with the Seattle Streetcar. Within Downtown Seattle, buses will travel eastbound on Spring Street and westbound on Madison Street in transit lanes, stopping near the University Street light rail station at 3rd Avenue and the Seattle Central Library at 5th Avenue. The route crosses over Interstate 5 into First Hill, where the two directions merge after 9th Avenue onto Madison, continuing to run in center transit-only lanes. The G Line crosses Broadway, with a station connecting to the First Hill Streetcar, and passes the campus of Seattle University before transitioning to mixed traffic east of 15th Avenue. The route continues into Madison Valley, serving several curbside stations, before terminating at Martin Luther King Jr. Way near the Washington Park Arboretum.[3]:8–11

The G Line is planned to have 1.98 miles (3.19 km) of dedicated transit lanes and 1.14 miles (1.83 km) of mixed-traffic business access and transit lanes.[3]:18

Stops and stations[edit]

The G Line is planned to serve 21 total stops on its route, including 10 stops in each direction and the western terminal near Colman Dock.[3]:8 Stations will be approximately 60 feet (18 m) long and feature off-board fare payment (including ticket vending machines), raised platforms for level boarding, branded shelters, real-time arrival information, and other features.[3]:10[4]

The G Line is planned to run 20 hours per day, with a headway of 6 minutes on weekdays and 15 minutes during weekends, and weekday mornings and evenings.[3]:14 Travel times from Downtown Seattle to Madison Valley are projected to improve from 16 minutes to 10 minutes with the G Line.[5]


The G Line is planned to be operated by 60-foot-long (18 m) articulated buses with low floors. The buses will be powered by electricity, either provided by an overhead wire (like the city's trolleybus network) or rechargeable batteries. The buses will have a total of five doors, three on the right and two on the left, for boarding at stations in the center and side of the roadway.[3]:14 An order for the vehicles has not yet been placed.[6]


The G Line project is expected to cost $120 million, and will be funded by a mix of sources.[7] Funding will be provided by a grant from the Federal Transit Administration, the 2015 Move Seattle levy, and the 2016 Sound Transit 3 ballot measure.[8][9][10]


The Madison Street corridor was identified as a bus rapid transit candidate in the 2012 Transit Master Plan, adopted by the city of Seattle with input from King County Metro.[11] While other routes were given feasibility studies for streetcars, as part of a new municipal system, Madison Street was considered too steep to support rail transit.[12] The Madison Street corridor, from Downtown Seattle to Madison Park, was historically served by cable car service from 1890 until 1940, when they were scrapped and replaced with motor buses and trolleybuses on modern-day routes 11 and 12.[12][13]

A design concept for the service was first presented for public comment in 2014, featuring two options for the eastern terminus, at 23rd Avenue or Martin Luther King Jr Way (MLK Way). A public survey was conducted and found higher support for the MLK Way terminus, as well as preferences for station locations and transfers to other transit routes.[14] In February 2016, the Seattle City Council approved a locally preferred alternative for the project and endorsed it to pursue federal funding.[15]

Residents of a condominium building on the line opposed the construction of a traction power substation that would be needed for the trolleybuses, citing possible health risks from exposure to electromagnetic fields.[16]

As of 2017, construction on the project was planned to begin in mid-2018, with the line scheduled to open in 2019.[7] However, it was later reported that uncertainty around federal funding was expected to delay construction.[17] As of spring 2018, an order for the vehicles had not yet been placed, and the postponement of the start of construction had pushed the projected opening date back to 2021.[6]
