On streets where buses and bikes are common, the “leapfrog” phenomenon has been a thorn in the side of the City of Portland for many years. It happens when a bus operator pulls all the way to the curb to service a stop — and temporarily blocks a travel lane used by bicycle riders. This behavior causes people to either stop and breathe toxic bus exhaust, or swerve around the bus into a more dangerous shared-lane environment. The issue has become more acute in recent years as the Bureau of Transportation has built more curbside lanes protected from drivers.
When a bus operator can still swing into a lane, it no longer qualifies as protected.
