Bike routes & boulevards
Portland has for many years been known as the most bicycle-friendly city in the United States.  Many features are designed into Portland's traffic patterns to make Portland's streets and special bike routes safer for the bicyclists, young and old.
Special bicycle lanes, traffic-calming intersection barriers, bike lanes separated from vehicular traffic (Terwilliger Blvd and Springwater Corridor, for example), and here
an alleyway which has been closed to vehicles but left open to bikes.
 Motor vehiches must turn left.
Bicycles may go straight
Special bicycles route markers help route finding.

SE 39th & Clinton
Bike Boulevards:  Bicycles may continue on Clinton across 39th in either direction, east or west.  Vehicular traffic must turn left or right onto 39th.  That greatly reduces vehicular traffic on this "Bike Boulevard" (Clinton Street), and bicycles have an east-west corridor especially suitable for safer bicycle traffic.  Bicycle-vehicle collisions are greatly reduced in these specially designed corridors.

Bike Box:   Bicycles are here given another special advantage, that space between the "STOP here on RED" line and the pedestrian crosswalk.  Bicycles thus get a head start over vehicular traffic when the light turns green.  This is an experimental device; for now--the only bike boxes in Portland are at this intersection.  Note the picture at the right: most cars park past the STOP-here-on-RED line and within the bike box.  Some education is needed!
