In cases where two routes share the same road, the through route should be the Primary Name with the second route added as an Alternate. If neither is the clear through route then the primary should be the higher type of the two, or the longer route shared if they are of the same type.
In rare cases where both routes are required, to ensure correct TTS the routes must be separated by a slash including spaces - "TRx / SRxx - Name". This should be discussed with your State Manager prior to using.
