Portland’s Sunday Parkways was inspired by the Bogota Ciclovia and successfully initiated by the City of Portland’s Bureau of Transportation in June 2008. The project was so popular and well received that they subsequently hosted 3 events in the summer of 2009 and are planning at least 5 events in 2010.
The City describes the opened streets during these events as “temporary parks” that connect various neighbourhoods in the city.  The program has leveraged huge support and donations from community volunteers, local businesses and agencies.  The approximately 6 miles of streets open to people and closed to cars feature various activities for people of all ages (hula hoop, tango, and live music) clustered in four parks along the route. Thousands of city residents participate in the events and enjoy the opportunity to do something different, meet new people, and be physically active.
