Modifies provisions relating to the establishment of alternative county highway commissions in certain counties

HB 1686 modifies how counties in Missouri can establish or abolish alternative county highway commissions. It requires counties with such commissions to get voter approval to adopt or disband them, or allow governing bodies to make the change. Counties without the alternative commission must choose between the standard county highway commission (under sections 230.010-230.110) or another commission structure (sections 231.010-231.130). The bill directly affects counties that currently use or may consider alternative highway commission models. It clarifies the voting requirements for implementing or ending this commission structure.
