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!

Coming to W Seattle Bridge & Aurora: Wet Paint

If you’re able, plan to avoid driving on the upper West Seattle Bridge in the wee hours, next Tuesday/Wednesday. Starting at 1 AM and wrapping before 7 AM August 29, our paint trucks will be in action. It’s a moving operation, so no closures involved; instead two paint trucks and back-up follow trucks will help precisely place the wet paint.


NOTE: It’s illegal to cross the newly placed lines!

Our crews will also be lining up Aurora (SR 99) next Thursday/Friday, overnight, from E Marginal Way near the Boeing Access Road, all the way up to the City line at NE 145th St. That striping work starts at midnight August 30, and concludes before 7 AM, August 31.


Again, if possible, avoid driving in these areas overnight, next Tuesday/Wednesday and Thursday/Friday. That will go a long way in reducing paint tracking and maintaining clear markings!


FYI, the work is weather dependent—water colors just don’t have the same staying power.

23rd Vision Zero work kicks off!

We’re enhancing safety and mobility on 23rd Ave E/24th Ave E, a key corridor connecting the University District and Capitol Hill. It’s part of our Vision Zero plan to end traffic deaths and serious injuries on city streets by 2030.


Data shows that people driving northbound between Boyer Ave E and E John St average 39 MPH. The posted speed is 30 MPH. The chances of someone being fatally or seriously injured increase significantly when struck at 40 MPH versus 30 MPH.


To improve safety for people walking, biking, and driving this corridor, we are converting one northbound lane of 23rd/24th avenues E to a center turn lane, from E John St to Boyer Ave E. The change encourages speeds closer to 30 MPH.

Work kicks off this week with spray-painting the street to mark the new traffic layout; removing old markings; and laying permanent traffic lines. Next week crews  install signs and finish details.


Similar design changes in other parts of the City have resulted in reduced vehicle crashes, and more drivers following the posted speed limit.



What you can expect:

The will work will be done in two phases, over 2018 and 2019. The first phase happens this month.

Monday, August 20 – Thursday, August 23 | 7 AM – 10 PM

Friday, August 24 – Saturday, August 25 | 9 AM – 10 PM

Monday, August 27 – Friday, August 31 | 7 AM to 10 PM

Crews may be on site up to 1 hour before or after noted work times, for prep and wrap-up.



  • Traffic reduced to 1 lane in each direction, NB and SB.
  • Occasional lane shifts around the work zone, as needed.
