Mercer Corridor Project – A Healthy Community is an Informed Community

A construction project on the scale of the Mercer Corridor Project (MCP) requires significant engagement with the countless individuals, businesses, and communities that are influenced by construction activities. As the MCP moves toward substantial completion later this summer, the outreach team continues to keep the neighborhood informed about everything from the overall schedule to details about specific closures. SDOT works diligently to keep commuters, residents, and business owners up to date to ensure our growing communities remain vibrant and healthy. Being knowledgeable of closures and alternative ways to get around and aware of one’s surroundings will help keep everyone safe in the Uptown and SLU communities.

SDOT’s commitment to keep you informed

The outreach team coordinates with the engineering, construction, and SDOT management crews to translate construction activities into understandable language for the community: what’s going to be closed, and when. They’re also sure to keep track of major events in the SLU, Seattle Center, and Downtown areas to minimize conflicts with race routes and other major construction closures. The team then sends this information out to the community through different pathways including email lists, notifications to neighborhood groups, media releases, and updates to the MCP website. Over the course of the project, the outreach team has sent out more than 1,000 email updates, neighbor notifications, and stakeholder outreach notices.

Don’t let construction stop you from enjoying all the community has to offer!

As you walk to Citizen Coffee, catch a show at McCaw Hall or Key Arena, visit the Bill and Melinda Gates Foundation Visitor Center, or shop for midnight snacks from QFC, make sure you are aware of the latest construction notices that can be easily found on the project website:

Building Healthy Communities with… SIDEWALKS!

From 2007-2013, SDOT noted an increase in children walking and biking to 26 of 28 schools evaluated in Seattle.* We’re working to continue this trend!

SDOT is helping to build healthy communities by participating in the national Safe Routes to School Program, focused on engineering and education projects to offer children in dense suburban areas safe and walkable routes to school.


Walking and biking to school on safe streets is always a good thing.


Two recent studies found walking to school associates with higher overall physical activity and other benefits that include:


  • Weight and blood pressure control
  • Bone, muscle, and joint health and maintenance
  • Reduction in the risk of diabetes
  • Improved psychological welfare
  • Better academic performance


Starting on June 29, SDOT will kick-off construction on three sidewalk projects in north Seattle:


  • 20th Avenue NE near Sacajawea Elementary School
  • 3rd Avenue NW near Viewlands Elementary School
  • NE 77th Street near Thornton Creek School


These projects are part of SDOT’s Pedestrian Master Plan and Safe Routes to School Program to make each route safer and improve the walking experience for all, including students at nearby schools.

Improvements include new sidewalks and curb ramps, revamped crosswalks and additional efforts to promote safe driving. Construction will conclude before school starts on September 8, just in time for that first walk to the classroom.

Construction Management Plans for ROW Impacts – COMING JULY 6

As the construction surge continues it’s increasinglyCMP blog photo2 challenging for construction projects to maintain access for motor vehicle, bicycle and pedestrian travelers. But one practice that has proved beneficial is the early creation and collaborative review of a comprehensive Construction Management Plan, or CMP.

When developers and contractors create CMPs and work with the City of Seattle to identify potential conflicts up front, projects run more smoothly. That’s why SDOT will soon be asking for CMPs from most mid- to large-sized projects that significantly impact the public right of way.

So what is a Construction Management Plan? A CMP is a pre-permitting document that clarifies how construction will be managed over the entire course of a project. It includes plans for traffic management, noise mitigation, pedestrian circulation, and parking.

Projects involving a State Environmental Protection Act (SEPA) review have always had to submit a CMP; as of July 6, 2015 those that significantly impact the public right of way will also need to submit a CMP at least two months prior to construction.

Since a CMP helps contractors and SDOT identify potential problems before construction begins, this new requirement will not only help keep the right of way usable for the public, it will also help save developers and contractors time and money. Small residential projects on non-arterials are not likely to require a CMP, but any project that either (1) significantly impacts the right of way, or (2) triggers a State Environmental Protection Act (SEPA) review, will require submission of a CMP before a Street Use permit will be issued.

Keep an eye out for details regarding CMP requirements, templates, and timelines when we launch our new CMP webpage on July 6.

If you’d like to inquire as to whether your project will require a CMP, or if you’d like to schedule a CMP coaching appointment, please contact the Street Use Applicant Services Team at, or 206-684-5283. Also, feel free to visit our Permit Services Counter on floor 23 of the Seattle Municipal Tower at 700 5th Ave.

Live from Lake City: Construction Update at Lake City Way and 24th Avenue NE


Crews are busy preparing the subgrade for drainage and sidewalk improvements.

Crews are busy preparing the subgrade for drainage and sidewalk improvements

The city continues their work to transform the intersection of Lake City Way NE and 24th Avenue NE. As noted previously here on the SDOT blog, this project will overhaul this intersection and provide new pavement, sidewalks, curb ramps and traffic signal controls. The changes will improve the safety for all users of these streets. When finished, drivers, pedestrians, and bicyclists will notice the significantly improved sidewalks and transit stop. Construction is expected to be complete in another 30 to 45 days.

Thanks to the outstanding summer weather, our contractor is making quick work. New curb ramps have been constructed on the east side of Lake City Way and excavation for the extensive sidewalks on the west side of the roadway is nearly complete. Over the next few weeks, crews will complete sidewalk construction and prepare foundations for new traffic signal mast arms.

This project was identified by the residents and business owners that have guided the Lake City Way Traffic Safety Project. SDOT and our partners will continue to implement priority projects for the next several years along this corridor.


Bike share your way around town!

Bike share can help you get around town faster and easier.

Bike share can help you get around town faster and easier.

If you need to make a quick trips on Seattle streets, consider signing up for bike share, an innovative program allowing users to take short trips easily without owning their own bike.

Pronto Cycle Share provides a fleet of specially designed and durable bikes found in docking stations located throughout Seattle. With this program, you can borrow a bike any time you like. The program is best for short trips – typically less than two miles.

Bikes can be picked up and returned to any station, creating an efficient network with many connection points, departures and arrivals.

One of the many bike share locations around the city-- 2nd & University.

One of the many bike share locations around the city– 2nd & University.

Bike share complements Seattle’s transit and light rail systems. In cities like Seattle, up to 50% of bike share trips are to or from public transit stations. In Seattle, bike share is used by commuters and tourists, for rush hour commuting, work or errand running, or moving among the city’s variety of attractions.

For more information on how to get involved, visit SDOT’S bike share page here.

When you don’t live near a bus route….

A Vanpool or Van Share may be the solution to your commute if there is no public transit near your home or near your workplace. Sharing a van is a convenient and cost-effective for the everyday commuter. You can use HOV lanes on the freeways, save money on gas and parking, and can shorten your commute instead of driving solo.

Metro Vanpool_Flickr_Oran Viriyincy

Van Shares you could be using!

Five or more people can form a Vanpool or Van Share. Vanpool participants share a flat monthly cost based on round trip distance and the number of people in the van. Van Share riders pay $185 each month, split among all riders. Gas, insurance and maintenance are all paid for both.

When you form a Vanpool, one person can act as driver and bookkeeper, but it’s nice if more people share these roles. You’ll enjoy discounted parking in some areas as well.

Van Shares are like Vanpools except they are limited to 20 miles round trip and must connect with transit, ferries, or trains for one leg of the trip. For example, you could use the Sounder commuter rail to arrive at King Street Station, and then pick up a Van Share in the garage and drive to your work outside of downtown.

RSO Vanpool Bike (48)

You can get help finding members for your van or attend a “ride share meetup” in your area this summer.

Proposed Protected Bike Lane in Fremont: We need your help!


You have an opportunity to provide input for a new protected bike lane segment along N 34th Street in Fremont!

More than 100 people bike on N 34th Street between the Burke-Gilman Trail and the Fremont Bridge during the peak morning and evening weekday hours. Currently, bicyclists share the road with people who drive vehicles.  There is an eastbound bike lane between Evanston Avenue N and Fremont Avenue N.

SDOT is proposing to extend the existing bike lane along N 34th Street from Evanston Avenue N to Phinney Avenue N.  We would convert it to a two-way protected bike facility that would accommodate people of all ages and abilities and provide a connection between the Burke-Gilman Trail and the Fremont Bridge. The existing parking configuration will not change.


Map of proposed changes on 34th between Evanston Avenue N and Phinney Avenue N.

This project is funded as part of the Bicycle Master Plan.

Please provide any feedback you have by June 26th to the project manager, Howard Wu at


Improving Pedestrian Crossing Safety in Ballard

SDOT broke ground this week on a pedestrian safety project at one of Seattle’s five-way intersections, this one in East Ballard near West Woodland Elementary School.

The project is located at the intersection of 3rd Avenue NW, NW 56th Street and 55th Place NW, where the street grid becomes complicated by roads that wind up Phinney Ridge. The intersection has been equipped with three striped crosswalks and a flashing “School Zone” beacon but the large, complex intersection remained difficult to cross.

Parents and the West Woodland Elementary School safety committee identified the need for crossing improvements on this key walking route through a Safe Routes to School outreach process.

West Woodland 6-18-15

In about two months, when this project is complete, kids, families and neighbors will find a new all-way stop, two additional striped crosswalks, curb extensions, upgraded curb ramps, and 55th Place NW will be separated from the intersection and made one-way southwest-bound.

These improvements are a part of SDOT’s ongoing mission to build healthy communities and were designed to help clarify the right of way, keep vehicle speeds low and improve visibility between pedestrians, bicyclists and motorists.

The SDOT project team designed this project over the past year, along with five other pedestrian safety improvement projects throughout the city. Each of these five projects are part of the Neighborhood Street Fund Program, with funding from both the Bridging the Gap transportation levy passed by voters in 2006 and scheduled to expire at the end of this year, as well as  from the Safe Routes to School Program.

Work began on June 15 and crews are in their first of what will be approximately eight weeks of construction. Residents and travelers in the area can expect construction activity while crews work to build these improvements, including some of the following impacts:

  • Temporary parking and lane restrictions on NW 56th Street, NW 55th Place and 3rd Avenue NW
  • Pedestrian and bicycle detours around the work zones
  • Noise, dust and vibration associated with concrete removal and paving
  • Typical weekday work hours, from 7 AM to 5 PM


Additionally, a road closure will be in place on 3rd Avenue NW at NW 56th Street for approximately three weeks, followed by a closure of the west side of 3rd Avenue NW at NW 56th Street for approximately three weeks. These restrictions will be in place to allow crews to safely and efficiently demolish the existing sidewalk and pour concrete for the new curb extensions. Local access will be maintained during these restrictions.

We appreciate the community’s patience while work is being done to complete this project.

If you have questions during construction, you can contact the outreach team at or call 206-733-9361. Sign up to receive email updates about this project here.

Summer Break for Kids has Begun, Please Travel Safely Everybody

Summer break has begun and we wanted to remind everyone to travel safely and to be mindful that most kids are out of school.

SDOT Director Scott Kubly, SDOT staffers joined Seattle Police Department (SPD) officers at Arbor Heights/K-5 STEM School in West Seattle last week to educate and reinforce safe travel habits as everyone prepared for summer break. Healthy habits developed as children can become lifelong habits that can be shared with others.

Please checkout our latest Blog Video featuring our friends at Arbor Heights/K-5 STEM, Seattle Police and Scott Kubly:

We chatted with grownups driving and kids who were getting dropped off, and families who were walking and biking to school and wanted to reinforce good travel behavior by saying thank and sharing some tokens of our appreciation.

Thank you to the staff, families and kids at Arbor Heights/K-5 STEM for letting us spread some positive safety reinforcement at your school, have an awesome summer break!

Seattle’s Vision Zero program launched earlier this year:

  • Goal is to end traffic-related deaths and serious injuries by 2030
  • Seattle is a safe city – often recognized as one of the safest in the nation
  • We want to build on our safety record
  • And we know that we can be even better (over 10,000 collisions/year, and one death is one too many)
  • Vision Zero approach emphasizes smarter street designs – forgiving streets that account for human error
  • When paired with targeted education and enforcement, we can save lives
  • We each have a role to play every day to reach Vision Zero

To make our streets safer for all, Seattle’s Vision Zero 2015 efforts include:

  • Reducing the speed limit in the downtown core to 25 m.p.h. by the end of 2015
  • Improving safety at 10 high-crash intersections downtown by eliminating turns on red lights, installing leading pedestrian intervals to give walkers a head start, eliminating dual turn lanes, and other engineering improvements
  • Installing 20 m.p.h. zones on residential streets in up to ten areas near parks and schools with documented collision histories
  • Enhancing safety on arterials (where 90 percent of serious and fatal collisions occur), like Rainier Avenue S, 35th Avenue SW, Fauntleroy Way SW and Fifth Avenue NE, by enhancing street designs, lowering speed limits and installing radar speed signs
  • Adding 12 new school zone safety cameras in six school zones to improve safety for children as they make their way to and from school
  • Adding seven miles of protected bike lanes, more than 40 crossing improvements, and 14 blocks of new sidewalk to make travel safer across all modes
  • Conducting targeted enforcement throughout the city for school, pedestrian and bike safety, along with enhanced DUI enforcement. SDOT and SPD will work together to educate people in advance of these patrols, so everyone will expect enforcement and better understand the rules of the road.For more information on Vision Zero, visit #VisionZeroSEA

Goat-powered Summer Vegetation Clearing in Seattle!

Our Goat friends along with Head Herder/Chief Wrangler Tammy are back in action for SDOT to help clear some unwanted invasive vegetation underneath the Viaduct near Leonora and Blanchard streets. Another example of SDOT using “green” technology to support environmental stewardship as summer approaches.

Goat powered vegetation clearing underneath the Viaduct.

Goat powered vegetation clearing underneath the Viaduct

The Goats will be around the next week or so, and are happy to clear the brush. As you may recall, Goats are waaay better suited to steep hillsides than humans, making it safer, more cost-effective and mutually beneficial to have this work done by goats than by humans. Clearing the invasive vegetation helps keep our eco-system and communities healthy by removing these non-indigenous quick growing plants. 

Baaaah...Baaah...We love Seattle almost-Summer.

Baaaah…Baaah…We love Seattle almost-Summer.

The Goats have four stomachs, so they can eat and digest the blackberry (thorns and all), and other invasive vegetation without repopulating the seeds anywhere, meaning they aren’t spreading the plants elsewhere.  We appreciate their “can-do” and “Goat-to” attitude.
