Wedgwood Neighborhood Greenways
39th Avenue NE Extension

Creating a network of family-friendly residential streets

June 27, 2016

Speed hump construction starts in July.

The Wedgwood neighborhood greenway on 39th Ave NE opened in 2012 and was extended north of NE 80th St in 2014. In 2014, we evaluated the existing greenway, which met many of our current design guidelines, but lacked speed humps to encourage calm speeds. To determine if speed humps were needed car volumes and speeds were analyzed. The speed in which 85 percent of people are driving at—or below—is 25 to 27 miles per hour (mph). This is higher than the posted speed limit of 20 mph and confirms speed humps are a good investment and we are moving forward with construction. At lower speeds, people driving can see more of their surroundings and have more time to react to possible hazards.

Project Description

Seattle is building a network of neighborhood greenways. Neighborhood greenways are safer, calmer residential streets for you, your family, neighbors and customers. On streets with low car volumes and speeds a greenway can:

  • Improve safety
  • Help people cross busy streets
  • Discourage cut-thru traffic
  • Protect the residential character of our neighborhoods
  • Keep speeds low
  • Get people to where they want to go like parks, schools, shops and restaurants

Neighborhood greenways are not car free zones, do not add bike lanes and there are minimal if any on-street parking impacts.
