Making The 8 Less L8! | Today – 8/28

One of the busiest stretches of Denny Way, eastbound from Fairview Ave E to Stewart St, is about to get a new transit-only lane—dedicated to moving many people efficiently. The project is part of a larger effort to address the historically late King County Metro Route 8, which serves an estimated 10,000 riders per weekday.

Work starts this afternoon, August 24, to transform one underutilized westbound lane of Denny Way for eastbound general-purpose traffic to Capitol Hill and dedicating the middle eastbound lane of the resulting three, to mass transit around the biggest single bottleneck that Route 8 experiences. The area is already bordered by construction projects, so crews can sometimes use will use the existing lane closures.


Route 8 currently runs 6 buses an hour per direction in peak periods. Separating the lane of cars turning right onto Yale to get to I-5 is expected to reduce lane merging friction and reduce congestion headed east on Denny Way to Capitol Hill.

Comprehensive and coordinated planning over the last four years has focused on better reliability for this key route in this location, and on sections of Route 8 in Lower Queen Anne, South Lake Union, and Capitol Hill. Besides enhanced Route 8 reliability, the change is also expected to benefit riders by:

  • Keeping more buses running on time, which in turn…
  • Reducing bus-bunching (jamming up at a bus stop);
  • Reducing wait times at important transfer locations (e.g. Capitol Hill Link); and
  • Making transit a more attractive travel option for crosstown travel in some of Seattle’s densest neighborhoods.


Capacity for mobility is critical, as Seattle growth continues, from 608,660 people in 2010 to more than nearly 730,000 in 2018 (click chart image for more details).

Much of the employment growth in downtown Seattle since the recession has been in South Lake Union, and Route 8 is a crucial connection for residents to access jobs, cultural destinations, and housing in central Seattle.


Crush loads…

The seated capacity of Metro’s 60-ft articulated coaches is 56 passengers, with a so-called ‘crush load’ equating to about 90- riders. As Route 8 riders likely know, crush loads are frequent during afternoon peak periods on this section of Denny, as are long wait times. Speeding up bus travel also provides operational savings to Metro and City-funded bus service.



The new bus lane is one piece of a set of improvements intended to enhance Route 8 speed and reliability. Although the changes are not expected to completely solve the reliability problems currently experienced on Route 8, together they should offer noticeable improvement.

Denny Substation Project, Aug 23, 2018 | Image by Seattle City Light | | John St on left; Denny Way on right.


Originally expected to be installed last year, we accommodated Denny Substation construction needs and are now implementing the design. The reconfiguration project is expected to finish Tuesday, August 28.


What you can expect:

This afternoon crews begin placing and bagging (until project completion) new signage between Fairview and Stewart.

Beginning at 7 AM Saturday, August 25, the team will hydro-blast (weather & equipment dependent) the street surface to remove existing street configuration markings; and then paint the new lines.

The moving operation will create additional, temporary lane closures through Saturday afternoon. Work is scheduled again Monday and Tuesday, 9 AM – 3 PM, to complete the project.


August 24, Friday | Noon – 3 PM | Closures
Crews need 1 – 2 rolling lane closures, and at times may be able to use those already in place for construction on both sides of Denny Way.


August 25, Saturday | 7 AM – 3 PM | Closures
As crews progress with mobile operations, there will be 1 – 2 rolling lane closures.


Monday August 27 and Tuesday, August 28 | 9 AM – 3 PM | Closures
Expect rolling lane closures during work hours, to finish project.


Thank you for your patience during this mobile operation!

What’s Moving Seattle | Weekender

Like we said earlier this week, this weekend is hot! But wait, there’s more….there’s preparing for Monday! What’s happening Monday, you ask?


How you get around downtown is changing.

On Monday, we’re optimizing bus service on 3rd Ave by extending bus-only hours. In other words, 3rd Ave will be dedicated for buses and bicyclists from 6 AM to 7 PM, seven days a week.

As the Washington State Department of Transportation plans for a full three-week closure as early as this fall, of SR 99 downtown – the Alaskan Way Viaduct – and the opening of a new SR 99 tunnel under downtown, we’re ramping up our strategy to deal with the traffic impacts in and around downtown.

Today, 3rd Ave is reserved for buses and people biking during the busiest weekday commute times (6-9 AM & 3-6:30 PM, M-F); starting Monday, 3rd Ave from Stewart St to just south of Yesler Way will be reserved for buses and bicyclists, 6 AM – 7 PM, seven days a week. So what does this mean for you? Get the details in our latest SDOT blog.

So have fun this weekend while also remembering this Monday change! The Seattle Police Department will cite people violating new restrictions in the coming weeks, but in the beginning, you’ll see officers educating people driving.


More AWV-related work.

Remember those construction ahead points we noted Aug. 3? Here’s an update…


Utility vault installation:

Through August 21, one WB lane on Madison St will be open, with all other lanes closed between Western Ave and Alaskan Way. The Office of the Waterfront is finishing installation of a vault to maintain utility service to area businesses, once the Alaskan Way Viaduct is demolished.


Installing new traffic signals/markings:

WSDOT expects construction for the Alaskan Way Traffic Switch to wrap up on or around Sept. 27, 2018. Crews are working north from the former ferry queuing lanes near Marion St, into current waterfront parking up to Pike St. They’re installing new traffic signals and marking new traffic lanes to prepare Alaskan Way for 2-way traffic (to be moved out from underneath the viaduct).



Pier 62/63 will impose lane restrictions on Alaskan Way through 8/31/2018 during non-peak travel times.

Columbia 2-way project is substantially complete and final inspections are underway. This project repaved Columbia St before it is converted to 2-way between 1st Ave and 3rd for bus routes, coming from West Seattle after the Alaskan Way Viaduct is demolished.


Rainier Tower construction impacts.

Crane installation:

On August 18, 5th Ave will be closed between Union and University streets to install the project’s third tower crane. Use 2nd and 3rd avenues for SB travel.


Pouring concrete:

September 7 at 10 PM through September 8 (possibly until Sept. 9) there will be full closures of 4th Ave, Union St, 5th Ave, and University St around the project to pour 11,000 cubic yards of concrete – over 1,000 trucks will deliver to the site that weekend.


Other impacts include the continued daily closure of one lane on Union St, 6 AM – 5 PM;  transit lane closure on 4th Ave, 6 AM – 3 PM daily; and sidewalk closures 24/7 on all frontages (Note: Rainier Square building is accessible).


Utility construction.

Streetcar utility work continues with the roadway now open between S Jackson and S Main streets, both NB and SB!


Next up:

  1. Full closures of 1st Ave S, Cherry to Washington streets, through 8/24/18 – alternating closures of SB 1st Ave and EB Cherry St to help move SB traffic off 1st.
  2. NB 1st Ave S, Main to Washington streets, reopens 8/24/18; NB 1st Ave S, Washington to Yesler will remain closed; Yesler to Columbia closed thru Sept. 28.
  3. Closures of 1st Ave SB between Cherry St and Yesler Way are limited to weekdays between 9 AM and 3 PM.  The closures are necessary to connect buildings on the west side of 1st Ave to the new water main.

Seattle Mariners vs. Houston Astros at Safeco Field:

  • August 20, 7:10 PM – 10 PM
  • August 21, 7:10 PM – 10 PM
