Ottawa County has a robust highway system covering some 150 lane miles. These highways systems provide direct linkage to other major east/west and north/south interstate corridors.  A series of well-maintained state routes (2, 19, 51, 53, 105, 163, 269, and 590) serve as connector roadways to residents and businesses located in rural areas.

This county facility is responsible for the mowing, maintenance, and plowing on the federal routes within and around Elmore, Genoa, Marblehead, Oak Harbor, Port Clinton, Rocky Ridge, and Put-in-Bay.
