In case you missed it, check out this helpful information from the Washington State Department of Transportation about impacts to Alaskan Way and Denny Way as part of the Alaskan Way Viaduct demolition and the North Surface Streets connections!

 

Check it out 👇👇👇

 

The viaduct is shrinking along Seattle’s waterfront and the work zone is changing this week as the contractor Kiewit shifts their work zone. Meanwhile, the rebuild of 7th Ave N will reach Denny Way this summer and fall with a series of lane reductions and street closures.

 

Around Alaskan Way in Pioneer Square, Yesler Way and S King St are reopen, and S Jackson St is closed.

 

 

Crews are removing the viaduct through Pioneer Square from both ends. Here are traffic control changes to expect this week:

 

  • August 20: S King St reopened at Alaskan Way
  • August 21: Yesler Way reopens at Alaskan Way
  • August 21: S Jackson St closes at Alaskan Way

 

Uniformed police officers will help direct traffic this week at key intersections during the evening commutes.

 

To reach Colman Dock: Vehicles can still enter the drive-on entrance at South Jackson Street by taking a left or right off Alaskan Way. Please allow extra time to reach your ferry as traffic congestion remains high on Alaskan Way.

 

People walking and biking: When S Jackson St is closed, your new east-west options between Alaskan Way and Pioneer Square are S King St and Yesler Way. S Dearborn St and Columbia St also remain open to bicycles and pedestrians.

 

Railroad Way S: This street will become northbound-only from S Dearborn St, with northbound vehicles forced to take a right on S King S. Vehicles can also turn onto southbound Railroad Way S from S King St, but the southbound lane terminates mid-block at the 505 Western Avenue building parking garage.

 

At the north end, prepare for weekend utility work and paving impacts at the intersection of Denny Way and 7th Ave.

 

The intersection of Denny Way and 7th Ave is the mixing zone for two projects, the filling and sealing of the Battery Street Tunnel and the North Surface Street Connections project. Starting this month, this intersection becomes a focus of work. View a map of the current traffic configuration in the area.

 

Crews will be repaving sections of the intersection and installing a duct bank just east of the intersection. Due to the intersection’s importance in moving buses and vehicles, this work will occur only on weekends.

 

Below is what to expect at the intersection of Denny Way and 7th Ave this summer and fall:

 

  • August 24 – 25: Denny reduced to 2 lanes between 6th Ave and Dexter Ave.
  • September 7 – 8: Denny reduced to 2 lanes between 6th Ave and Dexter Ave.
  • September 14 – 15: Denny closed between 6th Ave and Borealis Ave.
  • September 21 – 22: Wall Street closed at Denny Way, Denny reduced to 2 lanes between 6th Ave and Dexter Ave.
  • September 28 – 29: Denny closed between Borealis Ave and Dexter Ave.

 

Crews will also be working in the intersection on weekday nights, which will involve lane reductions but no full street closures. These closures are weather dependent.

Cowen Park Bridge facing north on 15th Ave NE

 

We are preparing to make seismic improvements to the Cowen Park Bridge to reduce the bridge’s vulnerability to earthquakes. Plan ahead and prepare for impacts to travel.

 

Here’s what you can expect:

 

SCHEDULE

Construction on the Cowen Park Bridge is anticipated to begin this fall 2019 and last approximately 6 months. We are in the final stages of selecting a contractor for this project.

 

CLOSURE | DETOUR

There will be redirects for people walking and biking across the bridge, as well as partial closures of walking routes within Cowen/Ravenna Parks underneath the bridge. Prepare for up to 2-3 full bridge weekend closures.

 

NOISE

There will be noise, dust, and vibrations during work hours, as well as equipment and materials staged near the work zone.

 

PROJECT OUTCOME

The planned seismic retrofits include several modifications to strengthen existing bridge components and reduce overall seismic vulnerability while preserving the bridge’s historic Art Deco character.

What’s the background on this project?

 

Cowen Park Bridge from below in Cowen Park

Cowen Park Bridge from below in Cowen Park

 

Infrastructure maintenance is critical for a healthy, vibrant, and connected city. As part of the City of Seattle’s efforts to invest in transportation infrastructure and address seismic vulnerability, the City established a bridge seismic retrofit program. Funded through the Levy to Move Seattle, the City selected 16 bridges for seismic retrofits, including the Cowen Park Bridge.  Approved by voters in 2015, the 9-year $930 million Levy to Move Seattle provides funding to improve safety for all travelers, maintain our streets and bridges, and invest in reliable, affordable travel options for a growing city.

 

Cowen Park Bridge was built in 1936, prior to the modernization of the seismic design code. It connects the Roosevelt/Ravenna neighborhood with the University District via 15th Ave NE across a ravine in Cowen Park. The bridge is listed in the National Register of Historic Places and is a designated City landmark.

 

 

Want more information?

 

We’re committed to keeping stakeholders informed and working with neighbors throughout the project to limit construction impacts to the extent feasible.

The redesigned 8th Ave includes a one-way northbound protected bike lane between Pike St and Bell St, one travel lane, paid parking and load zones, and new bike signals at busy intersection. This project completes a two-way couplet for people biking with the existing one-way southbound 7th Ave protected bike lane.

 

It will connect with protected bike lanes on Bell St and 9th Ave to get people to and from the Westlake Cycle Track and north Seattle neighborhoods, and it will connect with bike lanes on Pike St and Pine St to get people to and from greater downtown, Pike Place Market, and Capitol Hill.

 

This project also extends the Pine St protected bike lane between 7th Ave and 8th Ave in order to provide a connection to the new facility on 8th Ave.

 

We celebrated the opening of the bike lane on Wednesday, August 14 along with many members of the community!

Why did we install this bike lane?

 

Connected Bike Network Coming Soon!

A sign on the newly installed 8th Ave protected bike lane.

 

These improvements are part of the Center City Bike Network, which is a longstanding city priority to make center city streets safer and more predictable for everyone, have biking be a real transportation choice in our densest jobs center, and to maintain transit priority. The goal is to have these projects completed by the end of this year.

 

During the #SeattleSqueeze, Seattle’s period over the next five years where increased construction projects impact how we all get around downtown, it’s important for all of us to change our commutes to keep people and goods moving safely. Biking continues to be a great option during the Squeeze, and our numbers show that you all increased the amount of biking you were doing during the first chapter – keep it up!

 

We’re committed to providing bicycle options to keep you moving during the Seattle Squeeze and beyond to keep traffic volumes low and our collective spirits high.

 

What’s next?

 

  • PIKE ST: New protected bike lanes between 9th Ave and Broadway. A redesigned Pike St will include one general travel lane in each direction, paint-and-post bike lanes, parking removal, and reconfigured load zones.
  • 9th AVE N: New protected bike lanes between 8th Ave and Harrison St. The redesigned 9th Ave N and Bell St will include one general travel lane in each direction, paint-and-post bike lanes, no center turn lane, minor parking removal, and a new 4-way stop at 9th Ave N and John St.
  • SOUTH END CONNECTION: New 2-way protected bike lanes on 2nd Ave Ext S, S Main St, and 5th Ave S between the existing 2nd Ave protected bike lanes and the S King St Neighborhood Greenway. We’re redesigning these streets with separate bike facilities while maintaining transit priority. The project includes general travel lanes on a mix of 1-way and 2-way streets, paint-and-post bike lanes, and minor parking changes.

Plan ahead for Fairview Ave N. Bridge detour prep work on Aloha St, July-September

by

Starting the week of July 22, 2019, the Fairview Ave N Bridge Replacement Project will begin detour preparation work along Aloha Street, as they get ready for Fairview Ave N Bridge closure and replacement this fall.

 

Here’s what you can expect:

 

The work is needed to support safety and the flow of traffic during future bridge closure and focus on the three-way intersection at Aloha St and Yale Ave, and traffic movements at Fairview Ave N and Eastlake Ave E. During the detour prep work, portions of Aloha St will be closed and some of the changes will be permanent. Plan ahead and learn more about the work on the project webpage. The work will:

 

  • Install a new traffic signal at Aloha St and Eastlake Ave E and update the signal timing at Aloha St and Fairview Ave N
  • Install a permanently raised intersection with an all-way stop control at Aloha St and Yale Ave N

 

Schedule

This preparation work is expected to last approximately two months and will be completed before the Fairview Ave N Bridge is closed for construction this fall. Phase 1 will begin the week of July 22. Phase 2 will begin in mid-August. Each phase will last approximately 10 to 15 working days.

 

Closure | Detour

The work will occur on Aloha St, between Fairview Ave N and Eastlake Ave E, so impacts to travelers along Fairview Ave N or Eastlake Ave E should be minimal. Access to Fred Hutchinson and Seattle Cancer Care Alliance facilities will be maintained throughout construction, supported by local detours. Learn more about the Aloha St detour work.

 

Project outcome

Aloha St will be the pedestrian, transit, bicycle, and local traffic detour during bridge construction.

 

The project team will provide regular updates during Aloha St construction via email and the project webpage. Visit the project webpage to join the project email list.

Crews will be blocking the west lane on 5th Ave between Union St and University St from 9 AM to 3 PM, Monday-Friday to remove the guardrail beginning on Monday, July 22.

 

While this will impact travel for up to a few weeks, putting this structure in place saved years of disruption on 5th Ave.

 

Quick history lesson on Rainier Square, from 2017 to today.

Construction on the Rainier Square development on 5th Ave between Union St and University St began in late 2017 and is expected to be completed next year.

 

The original plan from 2017 was to close the travel lanes on each side (yep, that’s 4th Ave, 5th Ave, Union St, and University St – all of them) for two years. Our Construction Hub Coordination team had many meetings with their project team to minimize the impacts to the travel lanes, keeping them open for people to travel through the area.

 

In the end, to keep the travel lane open on 5th Ave, the teams reached a consensus to install a guardrail structure to protect people traveling through the area from the hole they were digging as part of construction.

 

Installing this guardrail kept the lane open for nearly two years since construction has begun, and now it’s time to remove it!

 

The initial proposal to remove the guardrail this July and August was to close a lane on 5th Ave 24/7 to complete the work. Our team found that the majority of the work will take place on site which will reduce the impact to 5th Ave. The conclusion was taking the west lane on 5th Ave only from 9 AM to 3 PM. While this may make the work take longer, it will create less overall impact to 5th Ave, helping you travel through the area more easily!

 

Here’s what you can expect.

SCHEDULE

 

The dates needed to remove the guardrail are tentatively scheduled for Monday, July 22 – Saturday, August 31. If work is completed before then, the lane will be reopened prior to August 31.

 

At some point before Thanksgiving, the west lane will need to be closed 24/7 for about two weeks to pour the curb back and remove the guard rail. After this, they will start pouring the sidewalk back. When that is completed, the sidewalk on the west side will be open again after 2 years of closure. The schedule for the sidewalk restoration is still being determined.

 

CLOSURE | DETOUR

 

Work will be occurring in the west lane of 5th Ave between Union St and University St from 9 AM to 3 PM, Monday-Friday. Plan ahead and prepare for increased travel times on 5th Ave.

NOISE

 

Noise will be mostly during the day for the curb and street restoration.

 

PROJECT OUTCOME

 

Completing this work now will allow the west sidewalk to be open for people walking prior to the Holiday Construction Moratorium, which is the restriction we place on construction in the Downtown Retail Core, Pioneer Square, and Chinatown-International District neighborhoods between Thanksgiving and the Lunar New Year. By restricting construction for the winter holidays, we support Seattle businesses during the peak shopping season and reduce traffic congestion during this busy time of year.

June 27: Lane reductions on 1st Ave S and Alaskan Way

 

The viaduct demolition contractor Kiewit is working on the viaduct’s remaining southern section around South Dearborn Street. Crews will need safe work space to remove the viaduct, which means lane reductions and sidewalk closures for people walking, biking and driving in the area. The map and the list below contain the planned roadway changes over the next several weeks.

 

  • Tomorrow: First Avenue reduces to one lane in each direction near CenturyLink field, south of South Dearborn Street. This narrowing will not extend past South Royal Brougham Way.
  • July: Streets between Yesler Way and South Dearborn Street will close at Alaskan Way while crews remove the viaduct running overhead.
  • Week of July 8: Railroad Way South closes both directions for four days.
  • Week of July 12: Yesler Way closes beneath the viaduct.
  • August: South Dearborn Street closes while crews remove the viaduct overhead.

 

You can follow progress by subscribing to Friday construction email updates, browsing the interactive tracker, and checking out photos of the work on Flickr.

Travel Alert: Changes to 1st Ave N for Seattle Center Arena Construction

by

A new traffic signal on 1st Ave N next to the Seattle Center Arena

 

Sidewalk and curb lane changes are being installed on 1st Ave N and a few intersecting streets as part of the Seattle Center Arena Renovation project. These changes allow access for truck hauling and construction staging, maintaining transit service, and separating people riding bikes from large trucks.

 

Changes include:

 

  • Restricting parking and loading areas on 1st Ave N;
  • Adding loading zones and designated disabled spaces on surrounding streets;
  • Installing a temporary protected bicycle lane on the west side of 1st Ave N from Denny Way to Roy St;
  • Adding a new signal at 1st Ave N and Thomas St; and
  • Relocating the northbound transit stop from John St to south of Denny Way.

 

Here’s what you can expect:

 

SCHEDULE

Most parking and loading restrictions have begun along the west side of 1st Ave N. The full signal will be turned on the week of June 24, and the roadway re-striping and the installation of the temporary protected bicycle lane will be complete prior to the beginning of July by the Seattle Arena team.

 

You may notice more activity at the site as demolition finishes and excavation begins in July, which will mean more large trucks and the start of nighttime work.

 

CLOSURE | DETOUR

Most changes will be on 1st Ave N between Denny Way and Roy St.  See the map below for a full view of all of the changes on 1st Ave N.

by

View of the SR 99 Aurora Bridge from the Fremont Bridge. Photo courtesy of WSDOT.

 

This weekend marks the beginning of series of lane reductions for pavement preservation work on the SR 99 Aurora Bridge over the summer.

 

From Friday night until Monday morning, contractor crews working for the Washington State Department of Transportation will scrape off old asphalt on the roadway, make any needed repairs to the bridge deck and repave.

 

This work is weather-dependent, so it could be postponed if there’s a decent chance of rain. Plan ahead and prepare for impacts to travel.

 

Here’s what you can expect:

 

SCHEDULE

Beginning at 7 PM Friday, May 31 until 5 AM Monday, June 3, both directions of SR 99 will be reduced to a single lane across the bridge to repave the southern part of the northbound lanes.

 

Additional bridge paving work is scheduled throughout the summer. Other weekend lane reductions scheduled so far are:

 

  • June 14-17
  • June 28-July 1
  • July 12-15
  • Aug. 9-12, 16-19 and 23-26

CLOSURE | DETOUR

Expect heavy traffic on Aurora Ave N, side streets, and I-5 as people work their way around this lane reduction. Know your trip and route options before you head out the door to reach your destination on time. King County Metro riders can stay up to date with Transit Alerts.

 

PROJECT DETAILS

This work is part of the project this summer to repave all of Aurora Ave between Roy Street near downtown Seattle and North 145th Street at the Seattle/Shoreline city limits. Most of the work will take place at night, but repaving the bridge requires weekends.

 

At least one lane in both directions of SR 99 will remain open during the work. Access to residences and businesses will be maintained during business hours.

 

Visit WSDOT’s website to learn more about the project schedule.
