This is what I have from a previous response. It should still be valid:

You need to add highway-symbol prefixes to your lines style file. Example:

highway=motorway {name '${ref|highway-symbol:hbox} ${name}' |
'${ref|highway-symbol:hbox}' | '${name|highway-symbol:hbox}'

From the source code, these are the possible values for highway shields:

		"interstate" // US Interstate
		"shield" // US Highway shield
		"round" // US Highway round
		"hbox" // box with horizontal bands
		"box"; // Square box
		"oval" // box with rounded end

The US symbols display only numeric values (e.g., "1", "401", etc).
The others are alphanumeric (e.g. "A5").

Cheers
