[Talk-us] Use of ref-tag on state highways

[Metcalf, Calvin (DOT)]

the issue there is that state route numbers along w/ 3 digit interstate spurs and beltways are only unique within a state and within a system. i.e. does ref=128 refer to the ma state oute thhe state route somewwhere else ror the first spur off I28
