Bicyclists and joggers are celebrating Portland’s upcoming shift in neighborhood speed limits. The Portland City Council has approved 70 miles of neighborhood streets that will get new 20-mph speed limits, down from 25 mph. Most of the streets lie north of S.E. Powell Blvd. and west of I-205, covering much of the existing Portland greenway network.
Proponents cite research from the National Highway Traffic Safety Administration that shows pedestrians hit by a car going 20 mph have only a 5% chance of being killed, versus a 40% chance at 30 mph. Read The Oregonian article and see its map of the affected streets.
