No there aren't two directions. There is only one road next to #422. On the other side of the street there might also be a road at #411 but that is (clearly) a different road. These aren't 4 way intersections. Instead it is a main road with what an American would call an alley branching off of it. And the same distinction applies in Vietnamese, I live on a hẻm ("alley") not on a đường ("road" or "street"). These side alleys are almost never big enough for two cars to pass. Sometimes they aren't even big enough for two scooters or bicycles to pass.
