Legislative route (Minnesota)

Though they are now listed separately in §161.114 of the Minnesota Statutes, the definitions are legally considered to be part of the constitution, and cannot be altered or removed without an amendment.

Legislative routes with numbers greater than 70 can be added or deleted by the legislature.

Until 1933 Constitutional Routes corresponded exactly to the number marked on the highways, but this is no longer necessarily the case.

There is some ambiguity in how literally the Minnesota Department of Transportation must interpret the constitutional routes.

Routes 390 to 396 were defined in and after the 1950s as portions of the Interstate Highway System "to take advantage of federal aid made available by the United States to the state of Minnesota for highway purposes".
