Portland has implemented one of the most sweeping commitments to traffic safety of any city in the United States: 20 mph speed limits over the vast majority of the city's streets.
"To improve traffic safety and make streets more welcoming for walking and biking, Portland will lower speed limits on nearly all of its residential streets to 20 miles per hour, in most cases replacing a 25 mph limit," reports Angie Schmitt.
According to Schmitt, the 70 percent of the city's collected miles of streets will now be subject to the 20 mph speed limit. Portland, like many other cities around the country, needed permission from the State legislature to lower its speed limits. Once it had that permission, the Portland City Council approved the lower speed limits unanimously.
The action by the Portland City Council is perhaps the most sweeping of any similar efforts around the country, though Portland is not the first city in the country or in the world to lower speed limits in the name of traffic safety. For more background on the movement, here is a list of articles on the subject:
