The Summary provides an overview of

the first phase of project development

for the I-405 Bus Rapid Transit (BRT)

project. Sound Transit began planning

for the I-405 BRT project as part of

Sound Transit 3 (ST3). During 2018,

Sound Transit considered and evaluated

community input and technical analyses

to refine the ST3 representative project

and develop a Proposed Refined Project.

The Sound Transit Board’s (the Board)

System Expansion Committee will

consider advancing the Proposed Refined

Project into the next phase of project

development, Conceptual Engineering and

Environmental Review.

BRT

Below is the Project Schedule, leading to the Start of Service in 2024:

*Construction for most of the BRT projects is expected to begin by 2023 and be completed by 2024. Construction of some elements may begin before 2023, and others may occur after service starts in 2024.


Sound Transit plans, builds and operates regional transit systems and services to improve mobility in urban areas of King, Pierce and Snohomish counties. A bus rapid transit system is being planned as part of Sound Transit’s ST3 system expansion program. BRT will provide fast, reliable bus service every 10 minutes in peak hours and 15 minutes off-peak along I-405, SR 518, SR 522 and NE 145th Street, connecting to light rail service in Bellevue, Tukwila, Shoreline and Lynnwood.

Project history


BRT will be part of Sound Transit’s high-capacity transit service and is being designed for fast and

reliable service, including frequent arrivals and departures. BRT will include features such as:

Unique brand identity for buses and stations

Transit speed and reliability

Off-board fare payment Real-time rider informationFrequent, all-day service

Unique station design

Entry and exit through multiple doors, level with

the station platform

Transit priority improvements, including business access and transit lanes, bus queue jumps,

and transit signal priority

Dedicated fleet of BRT buses

These features will help riders avoid traffic congestion and enjoy more frequent and reliable service.


The ST3 Plan included two BRT

projects, I-405 BRT and SR 522/NE

145th BRT. Both ST3 BRT projects

were based on high-level project

scopes, cost estimates and ridership

forecasts. ST3 also established transit

mode, general corridor, number of

stations and representative station

locations for both BRT projects.

I-405 BRT will have two lines

connecting communities along I-5, I-405 and SR 518 from Lynnwood to Bellevue and Bellevue to Burien with 11 BRT stations, a new transit center in South Renton, and a new bus base. Connections to Link light rail will be available at Lynnwood, Bellevue and Tukwila. Connections to the SR 522/145th BRT will be available in Bothell.

SR 522/NE 145th BRT will connect

communities from Shoreline to Woodinville via NE 145th Street, SR 522 and the transit center at UW Bothell/Cascadia College. The route has nine BRT stations and an expanded transit center at UW Bothell/Cascadia College. It will connect to Link light rail at the Shoreline South/145th Station and to I-405 BRT in Bothell.

Sound Transit is partnering with the

Washington State Department of

Transportation (WSDOT) to deliver the

I-405 BRT project. I-405 BRT builds

upon collaborative efforts between

Sound Transit, WSDOT, and other

local and regional partners, including:

• I-405 Master Plan (2002)

• I-405 Corridor Program

• I-405 Renton to Bellevue

Widening and Express Toll

Lanes Project

• NE 85th Street Interchange

Improvements Project

• Sound Transit Regional Transit

Long-Range Plan (2014)

I-405 BRT


Part of creating a new line of service is developing a new brand to

accompany it. Sound Transit calls our region’s commuter rail system

Sounder and light rail Link. Sound Transit is excited to welcome bus

rapid transit to the family and announce its name – Stride.

Sound Transit interviewed stakeholders inside and outside the

organization to help develop a BRT brand. Common themes heard

included a desire for the name to be memorable, short, easy to

pronounce, and integrate well with the overall Sound Transit brand.

The Stride name will be integrated with the design of the BRT

system, including vehicles, stations, signage and marketing materials.

The BRT system will have a unique design that helps riders identify

buses and stations. The Stride brand will:

• Differentiate BRT as premium transit service

• Help riders navigate the system by making BRT easily identifiable

and distinguishing it from other services

• Allow Sound Transit to more effectively reach existing and

new customers

• Create a sense of place at our transit facilities

• Generate excitement for public transportation and endure

for generations

Station design and branding

BRT station features• All-door entry and exit

• Off-board fare payment

• Level boarding at the platforms

• Lighting and directional signage

• Real-time rider information

• Sheltered and comfortable stations

• Unique brand identity

• Artwork

BRT station design Sound Transit will continue to

develop the BRT station design

during the next few years. The

rendering, left, shows the general

station design concept. While

stations will have a consistent

look and feel throughout the

Sound Transit BRT system,

station design at each station

location will vary based on

ridership and site conditions.

Share Proposed Refined Project

Sound Transit shared the Proposed Refined Project with our stakeholders. The project team will request the Sound Transit Board of Directors’ approval to advance the project into Conceptual Engineering and more detailed evaluation (including environmental review) in 2019.

4

Evaluate refinements

Sound Transit evaluated the project refinements using the objectives, evaluation criteria and technical analysis. Based on this evaluation, Sound Transit developed a Proposed Refined Project.

3

Develop refinements to the representative project

Sound Transit developed refinements based on technical analysis and stakeholder input. Technical analysis included collecting information on existing conditions along the I-405 corridor, identifying potential non-motorized access barriers, and conducting operations analysis through coordination with WSDOT, cities, transit agencies and other local and regional partners.

2

Start with the ST3 representative project

The representative project identified the high-capacity transit mode (BRT), the 11 BRT station locations and the parking facilities that would be developed as part of the project.

1

Project Objectives• Improve speed, frequency and

reliability in the corridor

• Increase regional mobility

• Deliver the project on-time and

within budget

• Develop stations to support

safe and convenient access for

multiple modes

• Encourage equitable transit-

oriented development

• Promote a healthy and

sustainable environment

Evaluation Criteria• BRT travel time

• Service reliability

• Non-motorized access

• Transit access

• Vehicular access

During this Planning Phase 1 in 2018, the BRT Team used the following

process to develop project refinements, review and evaluate those

refinements, and share the refinements throughout the corridor:

Project refinement process


I-405 BRT will build upon WSDOT’s I-405 Master Plan with corridor improvements facilitating faster bus travel.

WSDOT is currently improving I-405 as part of the I-405 Corridor Program. WSDOT projects include the I-405

Renton to Bellevue Widening and Express Toll Lanes Project with construction expected to begin in 2019 and

design efforts under way in the north corridor between SR 522 and SR 527 (I-405 - SR 522 to SR 527 Capacity

Improvements Project). These projects are designed to improve speeds and trip reliability for all travelers and support

the future I-405 Bus Rapid Transit line.

Sound Transit also works closely with King County Metro, Community Transit and other local and regional

transportation agencies to determine routes, ensure fast and seamless transfers, and provide integrated transit

services that best serve the needs of the community.

Sound Transit will continue to coordinate with our transit partners to integrate I-405 BRT with local and regional

transit service.

• BRT station at existing Burien Transit Center

• Connections to local buses and RapidRide

• Evaluating transit speed and reliability improvements

to/from Burien Transit Center

Speed and reliability improvementsTransit priority improvements help buses move through traffic

more efficiently and can include bus lanes and transit priority

signals. Sound Transit will continue to coordinate with our

partners to evaluate opportunities to improve travel times

along the route during Phase 2.

To maintain travel times, I-405 BRT will operate as two

service lines. The north line will run from Lynnwood to

Bellevue. The south line will run from Bellevue to Burien.

Riders traveling between the north and south lines will

transfer in Bellevue.


I-405 BRT performanceThe Proposed Refined Project has higher ridership projections (year 2042) compared to the ST3 Representative Project.

The changes in ridership reflect the anticipated growth in the region as well as the refined station concepts and resulting

faster travel times.

Next stepsSound Transit will continue its work on all Proposed Refined Project elements with communities and stakeholders along

the corridor, transit partners, the IAG and the ELG in Phase 2 - Conceptual Engineering and Environmental Review during

2019 and into early 2020. The following next steps will also be part of the Phase 2 process:

• Fieldwork and technical studies

• Stakeholder involvement

• Partner agreements

• BRT vehicle fleet analysis

• Conceptual design for a new bus

base, Bus Base North

• Station design development

The “low” forecasts assume less development, while the “high” forecast assumes more development as well as a per-mile fee for vehicles, which leads to more transit use. All projections are for 2042.
