Shoot. Guess I'll have to go back and fix them all!

Quick question, if an exit guide sign says, for example, 
"Exit 42
To Route 159
Windsor Locks"
does that mean the syntax should read "destination:ref:to=Route 159" or is it preferred "destination:ref=To Route 159"? I just want to make sure I have that correct.
I know that on non-expressways "destination:ref:to" is what should be used.
