Yes, such asymmetries are common. The most common examples are central turn lanes before an intersection, for use by vehicles turning across oncoming traffic; deceleration lanes for vehicles turning away from oncoming traffic; acceleration lanes for vehicles that just turned onto the road from a side road; and outside lanes for slower traffic to use when climbing a long hill.
