Upcoming striping for Business Access and Transit lanes

Seattle DOT striping for bus lane example.

Construction teams will begin striping new Business Access and Transit (BAT) lanes in White Center and Burien as soon as later this month, weather permitting. BAT lanes are curbside lanes used only by right-turning vehicles and buses. They help buses move more efficiently through traffic and provide better access to businesses. BAT lanes will be installed along 16th Ave SW between SW 107th St and SW 116th St, and on Ambaum Blvd SW between SW 128th St. and SW 148th St. Some lane closures and detours will be in place during this work.

Answers to your commonly asked questions

What is RapidRide H Line?

RapidRide H Line, previously known as Route 120, is one of our 10 busiest routes. It will provide connections from neighborhoods in Burien, White Center, and West Seattle to downtown Seattle along Third Avenue. RapidRide H Line will also provide needed connections to other bus routes and Link light rail.

How is RapidRide H Line different from Route 120?

RapidRide H Line buses will operate more reliably, and riders will have access to more peak commute trips operating in the reverse direction and more trips operating at night on weekends. Bus stops will be upgraded with new shelters, lighting, and real-time arrival information to improve your experience. Sidewalks, street crossings, and signals will be improved around stations for pedestrians, bikes, and those with limited mobility. Additionally, new business access and transit (BAT) lanes will be added to improve travel times for transit and provide better access to businesses for drivers.

What are the construction hours and how long will construction last?

Typical work hours for the RapidRide H Line project are Monday through Friday, 7 a.m. to 3:30 p.m., with some nighttime and weekend work. Majority of construction is expected to last through March 2023 with some construction to last beyond 2023.

Will access to businesses be maintained throughout construction?

Access to businesses will be maintained throughout construction. We are reaching out to neighbors, businesses, and local community organizations in advance of construction near them to share when and where work will happen, as well as what impacts to expect.

Why was construction previously delayed?
Construction on RapidRide H Line was previously delayed due to a region-wide concrete driver worker strike.

Why does construction start at new locations without others being completed?
The limited and unpredictable availability of concrete resulted in crews balancing the work they can do with what materials are available to continue that work. In order to maintain the overall project schedule, we have begun several new locations where crews have the resources and materials to complete the work, while also pausing some work at other locations, as necessary. Crews are continuing to make swift progress on work throughout the project area and we look forward to being able to wrap up work at some sites throughout the project area later this summer.

Where is construction happening now?

Where crews are doing construction varies week by week. For more details about the locations where work is ongoing, see the “What’s Happening Now” section on our project website or visit our blog for more information. You can also sign up for project updates here.

What work will be done over the winter months?
Crews will focus on shelter installations, excavation, concrete pours, and landscaping over the winter months. See the construction map for more details. Low temperatures and consistent rain will require that paving work will shift into next year when warmer temperatures return. In locations where work is paused, we will be securing equipment, consolidating traffic control, and covering open holes to ensure safe traveling conditions.
