A USRN is assigned to the complete street feature and is made up on junction-to-junction segments. It is mandatory for all USRNs to be assigned a Street Type. All streets must have a Type 1 or a Type 2 USRN assigned, but a Type 3 or Type 4 USRN can also represent the same sections of carriageway that the Type 1 or 2 are assigned to.
