Of course.  But redirects can go in either direction.  Personally I think that both State Highway x (Minnesota) and Minnesota State Highway x are defensible.  But on the talk page all contributors except you agreed to stick with the existing usage of Minnesota State Highway x, which is the form already in use on Wikipedia in many Minnesota highway articles.  So that issue is settled.  Given that, and given the fact that this usage also is common usage in Minnesota and in official publications by this state, it is not helpful to have people going into the articles themselves and changing wording from Minnesota State Highway x to some variant without the Minnesota attributive in the compound noun.  It appears like an atttempt to accomplish indirectly what the participants in the discussion (other than you) agreed should not be done in the title.  I am not challenging your good faith, but I am suggesting that the articles with text using the term Minnesota State Highway x be left alone as they are consistent with common and official usage.
