We’re working to connect the cities of Renton, Kent and Auburn with fast, frequent and reliable bus rapid transit service

Public transit is an important part of how we will meet the diverse needs and priorities of our rapidly growing region. Our current growing demand for transit requires access to public transportation that is fast and on-time.

RapidRide I Line improvements

The I Line will be an upgrade to current Route 180 between Auburn Station and Kent Station combined with current Route 169 from Kent Station to Renton. When it launches in 2023, it will come more often and be more reliable (on-time) than the current routes.

  • Buses will come more often and be more reliable (on-time).
  • More service will be added at night and on weekends.
  • Buses that get you where you need to go faster.
  • Some bus stops will be upgraded with lighting, real-time arrival signs and off-board ORCA card readers.
  • Sidewalks, street crossings, and paths for getting to stops will make it easier and safer to get to/from bus stops.

Renton-Kent-Auburn Area Mobility Plan

Metro has begun working on an area mobility plan in south King County that will serve communities within the West Valley and East Hill. The plan will integrate RapidRide, other fixed-route and dial-a-ride transit (DART) buses and Metro's Community Connections Program, which could include cost-efficient transportation options in areas that don’t have the infrastructure, density, or land use to support regular, fixed-route bus service. Parts of this mobility plan will go into effect in September 2020, and the RapidRide I Line will be in service in 2023.

As we plan this transition, we'll gather input from affected communities and riders on all changes we consider. We'll also gather input on changes to the broader mobility network as part of the Renton-Kent-Auburn Area Mobility Plan.

What’s happening now?

Metro is talking with communities along the future I Line route to learn their needs and priorities for the new RapidRide service and other mobility needs in the area. We'll work with these communities and our other partner jurisdictions to gather input that will inform decisions on…

  • The new RapidRide line's route.
  • The best places to put RapidRide bus stops (also called stations).
  • Projects that improve safety for all kinds of travel in the corridor.
  • Projects that improve access to transit by making it easier, safer, or more convenient to get to—or wait for—the bus.
  • Ways to balance bus and general vehicle use on roads that have limited capacity to keep people moving as our region grows.

Why upgrade to RapidRide?

Current ridership

Routes 169 and 180 are two of the busiest Metro routes in south King County carrying nearly 8,000 riders each weekday, nearly 6,000 of them in the areas that will be served by the RapidRide I Line.

Transportation connections

Over two-thirds of current Route 169 riders, likely future RapidRide I Line riders, use the route to transfer to or from other transit service including the RapidRide F line, Sound Transit’s Sounder Train and Sound Transit buses.

Community needs

Improvement to Metro’s service in South King County will serve both existing and future communities in Auburn, Kent and Renton.

Upcoming milestones

  • Public outreach on local needs and priorities:
    Metro reaches out to riders, the public, and stakeholders in the communities to gather input about current transit service and future mobility needs.
  • Concepts Developed:
    Metro works with partners, including the Sounding Board, to develop draft mobility concepts based on input from the public.
  • Feedback on Mobility Concepts:
    Metro shares new mobility proposals and I Line routing with the public, stakeholders, and local jurisdictions and collects feedback.
  • Proposal Developed:
    Metro works with the Sounding Board and other partners to make adjustments and refine mobility concepts to develop a single preferred proposal based on feedback received from the public.
  • Feedback on Proposal:
    Metro shares the proposal with the public, stakeholders, and local jurisdictions and collects feedback.
  • Recommendation:
    Metro finalizes a recommendation.
  • Recommendation is transmitted to the King County Council for adoption.
  • If adopted, the recommendation becomes part of the Fall 2020 service change.

Community involvement

Mobility Board

Metro is currently recruiting members to be part of our Mobility Board for the Renton-Kent-Auburn Area Mobility Plan. We are looking for community members who live, work and travel within the area to advise Metro about service change concepts and proposals as well as ways Metro can engage with the community.

Team members attend regular meetings and participate in public meetings and outreach events to hear from the local community.

They help Metro identify and prioritize transit service needs, examine inefficiencies in current service, evaluate tradeoffs given existing resources, and develop recommendations for the final proposal for the Plan.

If you are interested in being a part of the mobility board please sign up and we will contact you.
