5th/6th Transit Pathway

Updated: February 26, 2019

What's happening now?

Starting Saturday, March 2, we will begin installing the new 5th/6th Transit Pathway along 5th Ave and 6th Ave downtown.

We will remove existing road markings and lane stripes by "hydroblasting," which can be loud, and then install the new lane stripes markings. This will create the new peak-only bus lane that will move thousands of people efficiently out of downtown each weekday evening after buses come out of the bus tunnel on March 23. 

We will work from 7 AM Saturday, March 2, to 11 PM Tuesday, March 5. All noisy work will be completed between 9 AM - 10 PM on weekends, and 7 AM - 10 PM on weekdays. The approved noise variance permit will be posted at least 72 hours prior to work starting. See the Noise Variance Notice for more information.

During this work, you can expect:

  • "No Park" signs near the project area at least 72 hours in advance of work starting
  • Noise, dust, and vibrations during the hours mentioned above
  • Intermittent lane restrictions and reroutes as crews move along the corridor

Project Overview

A new transit pathway on 5th Ave and 6th Ave from Cherry St to Olive Way will provide more transit capacity and improve travel time and reliability for northbound buses. The King County Metro routes that will use the new transit pathway to access I-5 northbound include: 74, 76, 77, 252, 255, 257, 301, 308, 311, 316. The existing, northbound transit lane on 5th Ave will be extended 2 blocks to Marion St, where it will connect to 6th Ave and continue north to Olive Way.

The pathway will consist of an east side painted bus lane in effect 3 - 7 PM, Monday - Friday. We'll install 3 new bus stops, widen existing lanes, add right-turn signals, and remove or alter some parking.

The new northbound transit pathway will also include new bus stops at Marion St, Union St, and Pike St. By increasing transit capacity on these streets, we can move more people efficiently in the center city during the Seattle Squeeze. Bus service will be outbound only, and mostly in the evening peak period.

Parking Changes

Some on-street parking will be removed and new time limits will be added to some remaining parking spaces. On-street loading zones, and access to alleys, off-street parking garages, and loading bays, will also be maintained on most blocks. See the map below for more details. 

Benefits

Creating an exclusive, transit-only pathway boosts reliability, travel speed, and capacity. This helps balance the street network so that the travel mode that carries the most people - transit - gets more dedicated space. 

To serve transit effectively, the pathway lane(s) will be closed to all private vehicles during pathway operating hours, which include the evening peak period (3 - 7 PM) on weekdays only. We're looking at access options for the pathway during other times. Emergency vehicles and first responders can use the pathway, but private for hire vehicles and shuttles cannot. 

What's a transit pathway?

Transit pathways make riding the bus faster and more reliable in congested urban settings like downtown Seattle. They are investments in moving people to and through downtown Seattle. Dense, constrained street grids have the highest potential transit ridership and tend to be places with the slowest and least predictable traffic speeds. 

Transit pathways create exclusive, transit-only lanes that get turning vehicles, frequent stops, and unpredictable traffic movements out of buses' way. They boost reliability, travel speed, and capacity which promotes the quality of the transit line and system.

Project Background

A new era of tough traffic will begin when the Washington State Department of Transportation (WSDOT) permanently closes the Alaskan Way Viaduct in early 2019. 

Even after the new SR 99 tunnel opens, transportation challenges will continue as buses move out of the transit tunnel to make room for the Washington State Convention Center addition and extending light rail; our region continues to grow; and private and public projects reduce capacity on our streets. We'll all have to adjust to a new normal. 

But there's good news. The City, WSDOT, King County Metro, Sound Transit, and the Port of Seattle are working together to keep people and goods moving, and when work is done we'll have a world-class downtown. 

Schedule

Our plan is to update signals, paint lanes, and build new bus stops in early 2019, and open the new pathway to transit riders on March 23, 2019.
