2008 Arterial Asphalt & Concrete Program

Denny / Western / Elliott / 15th Avenue West Paving Project: FAQs

1. Why is the Denny/Western/Elliott/15th Avenue W corridor being repaved?

The Denny/Western/Elliott/15 th Avenue W corridor is an important part of Seattle’s Center City transportation system. It is one of the primary arterials leading into and out from the Center City area. Due to heavy use over the years the corridor’s paving is in poor condition.

As part of the Bridging the Gap Transportation Levy passed by Seattle voters in 2006, funding has been set aside to repair and repave the corridor. In addition, the paving of this corridor is part of a larger program to prepare the primary north and south connectors in the downtown core for increased traffic during major construction on the Alaskan Way Viaduct (Central Waterfront section).


2. What is the scope of the project?

Denny Way (First Avenue N. to Western Avenue N.), Western Avenue W. (Denny Way to W. Thomas Street), Elliott Avenue W. ( W. Thomas Street to W. Galer Street), and 15th Avenue W. ( W. Galer Street to W. Emerson Street/Ballard Bridge) will be repaved The work includes grinding and removing the top layer of existing asphalt, repairing portions of the base beneath the asphalt, and overlaying the base with new asphalt. New curb ramps will be installed or upgraded to meet current standards. Work elements also include installation of signal detectors and new pavement markings for lane configurations, including Business Access and Transit (BAT) lanes.


3. When will the corridor be repaved?

Weather is a major factor in determining when particular projects can be constructed. The months of April through October are the best months for construction in Seattle. Paving especially needs the predictability of the fairly warm and dry conditions offered only during that time period. As a result, the Denny/Western/Elliott/15 th Avenue W corridor paving will take place between April and October 2008.


4. How will this project benefit me?

New pavement makes quieter, smoother and safer travel for bicyclists, cars and pedestrians. Drivers can focus on their driving instead of avoiding potholes. New markings are more visible to drivers day and night ensuring a safer and more efficient flow of traffic. Pedestrian access and safety will be improved as curb ramps are upgraded.


5. How long will the work last?

The project will last approximately six months from beginning to end. We selected a contractor in January of 2008, and plan to start construction in April and complete the work in the fall 2008. However, not all of the Denny/Western/Elliott/15 th Avenue W corridor will be under construction at the same time. The contractor’s work will progress through the area in a logical manner, to allow for the most efficient use of time. We will distribute the schedule of work when it becomes available.


6. What can I expect during construction?

The construction will create noise, vibrations and dust. This project will also require temporary lane closures, pedestrian detours and parking restrictions.

7. What are the work hours?

Work hours will generally be 7a.m. – 4p.m., with occasional grinding and paving at night and on weekends. The work zones are often set up and taken down each day in the area of work where the contractors are working, although some work requires lane closures for 24 hours.


8. What about noise?

This project will generate significant noise at times, especially when pavement breaking is necessary. Night work will also generate some noise however pavement breaking is prohibited after 10 pm.


9. Will I have access to my business?

Access to businesses will be maintained throughout construction. There will be some isolated times when a driveway will have to be temporarily closed. This will be discussed individually with the affected property owner/business manager in advance of the closure to minimize the impact.


10. Will there be lane closures along the corridor?

Yes. Lane closures along the Denny/Western/Elliott/15 th Avenue W corridor can be anticipated. We will make every effort to keep as many lanes open in the peak direction at the peak times.

Lane closures create safe work zones. Parking, travel lane, and pedestrian restrictions may be required to promote safe and efficient movement through the work zone. (There may not always be work going on everywhere behind the barrels/cones but the zone is part of a larger traffic control set up to ensure safety).


11. Will there be sidewalk closures?

Sidewalk closures/detours will occur. During curb ramp repairs to sidewalks, the contractor is required to keep pedestrian access available to cross the street, even if it might mean going to the opposite side of the street and back for crossing.


12. How do I report issues or problems?

Issues and/or problems can be reported to George Frost, Public Outreach Coordinator, at 615-0786 or


13. What forms of communication will be used to notify business owners?

SDOT will employ a variety of communication methods to notify businesses and other affected parties along the Denny/Western/Elliott/15 th Avenue W corridor . These include a project website, information phone line, door-to-door outreach and regular construction notices. To sign up for electronic updates please visit:

SDOT is working closely with property management companies and transportation coordinators of major employers and businesses to alert business owners of this and other upcoming construction projects. SDOT‘s Public Outreach Coordinator and Project Manager work together to assure distribution of information promptly and to respond to questions from nearby businesses and residents.
