With your feedback, Metro identified locations along the Burien portion of the route where changes to bus routing, roads, sidewalks, and stations are to be made. Changes the community should expect to see:

Station Locations

RapidRide stations will be located approximately 1/3 of a mile apart throughout Burien. Station locations were determined and evaluated with community input during outreach conducted during Phase 1 of public engagement. While a majority of the Route 120 stops will be kept, the upgrade to RapidRide H Line will bring new stops and a balancing of stops.

Bus Routing

RapidRide H Line will deviate slightly from the existing Route 120. Instead of traveling along SW 148th St to and from the Burien Transit Center, RapidRide H Line will travel along SW 150th St. The new routing was decided upon to make it faster and easier for community members to access downtown Burien businesses and community gathering spaces.

Safety Improvements

Several road and pedestrian safety improvements will be made along the route to make it easier and safer to get to and use the bus.

Improvements include:

  • New traffic signals
  • New ADA accessible ramps
  • New pedestrian crossing signals
  • Roadway safety improvements along Ambaum Blvd SW between SW 116th St and SW 120th St to deter speeding and reduce crashes

Areas of improvement were determined with input from traffic studies, community needs and priorities surveys, and community feedback during outreach in winter 2017, spring 2018, and fall 2018.

Frequent, Fast, Easy

RapidRide buses get you to your destination faster. They move more and stop less, getting a boost from bus-only lanes, priority bus signals, and roadway improvements. Buses are equipped with three sets of doors for all-door boarding and exiting, plus ORCA card readers at the station for easy payment and on-time arrival information so you know exactly when the next bus will arrive.

More Service

Metro heard from the community about the need for more service. Upgrading Route 120 to RapidRide means more buses traveling in the direction you need to go, when you need to go. RapidRide buses come at least every 15 minutes all day, every day, so time schedules are no longer needed. During peak hours, buses arrive at least every 10 minutes, resulting in more buses heading north in the morning and south in the afternoon and evening.

What are BAT lanes?

What are BAT lanes?

Business Access and Transit (BAT) lanes are curb lanes used only by right-turning vehicles and buses. They help buses move more efficiently through traffic and provide better access to businesses.

How can BAT lanes help improve travel times?


Transit riders

A designated bus lane allows buses to move more freely, leading to greater opportunity for on-time arrivals.



BAT lanes enhance the capacity of general-purpose lanes by removing buses from general traffic.

Wherever a BAT lane is available:

  • Drivers don’t get stuck behind the bus as it makes frequent stops
  • Turning right at intersections and into driveways is easier, because BAT lanes provide better visibility and opportunity to turn
  • Travel is faster for vehicles using the general-purpose lanes, as they are no longer delayed by turning vehicles

BAT Lanes at a Glance

Bus Access Only


BAT lanes are for bus travel only during designated times (either 24 hours or during peak hours). Check surrounding signage. Accessing businesses and making right turns are permitted from a BAT lane.

Don’t Travel in the BAT Lane


Do not travel in the BAT lane during restricted times. When necessary, travel is limited to one city block and should be used only to access a business or make a right turn.

Turn into the Nearest Through Traffic Lane


When leaving a business, be sure to turn into the nearest through-traffic lane and not into the BAT lane.

Don’t Park in the BAT Lane


BAT lanes are usually curb lanes but should not be used for parking during the designated BAT lane hours. Check surrounding signage for allowable times to park (if at all).

BAT Lanes Make Turning Right Easier


Drivers can make right turns from BAT lanes. BAT lanes make turning right (into a business or residence and onto connecting streets) easier by removing obstructions.
