Thank you for your interest in the Levy to Move Seattle.
It’s important you know where your tax dollars are going. Earlier this year, we started something new. Every two weeks, we are highlighting a Levy program or project in this newsletter.
Levy to Move Seattle Program Spotlight
Program 4 - Transportation Operations
Our Levy to Move Seattle commitment: Maintain and improve the City’s system of traffic signals, signs, and markings.

SDOT maintains a system of over 1,100 traffic signals, as well as hundreds of thousands of signs. While it doesn’t always make the news, our work on traffic signals and signage makes a big difference for people walking, rolling, biking, taking transit, traveling by car, and delivering goods and services.
To meet our Levy commitment, annually we install new traffic signals, make signal and traffic spot improvements, replace regulatory signs (like Yield, No Parking, STOP, or similar signs), and optimize the signals on specific corridors for efficient travel.
New traffic signals:
We install new traffic signals to improve safety and efficient flow of traffic. Earlier this year, we installed a new traffic signal at Roosevelt Ave NE and NE 103rd St to improve crossing safety on the Northgate Neighborhood Greenway.
In 2021, new traffic signals were installed at NE 125th St and 28th Ave NE; Martin Luther King Jr Way and E Alder St; and on W Marginal Way SW at Herrings House Park and the Seattle Public Utilities South Operations Facility. This new signal provides safer access for those visiting the Duwamish Longhouse and people walking and biking on the Duwamish Trail.

Traffic spot improvements:
One recent traffic spot improvement we made was creating an all-way stop at College Way N & N 100th St in North Seattle. An all-way stop at this intersection makes crossing safer and more predictable for people walking, rolling, biking, and driving through this intersection.

Signal improvements:
We perform preventative maintenance on signals around the city to keep traffic flowing smoothly. As traffic patterns and conditions change, we often look at opportunities to make adjustments to signals to accommodate these changes. This type of improvement includes things like adding a left turn signal phase at an intersection.
Corridor optimization:
Throughout Seattle, we have been revising pedestrian signal timing to give people more time to cross the street. This past winter, we did this at five signals on Rainier Ave S from S Jackson St to S Charles St. Synchronizing traffic signals can reduce congestion, fuel consumption, and travel times. Optimum signal timing is when all people traveling have the least amount of delay possible. This includes reducing the number of stops vehicles make at red lights on a given route, helping transit or bicyclists travel more efficiently, or reducing how long pedestrians must wait to cross the street.
Thank you making this work possible through the Levy to Move Seattle.
