The American Association of State Highway and Transportation Officials (AASHTO) approved U.S. Bike Route (USBR) 30 and USBR 230 as Wisconsin’s first nationally designated bicycle routes. The 269-mile USBR 30 crosses the state from east to west. It begins in Milwaukee, at Lake Michigan, and ends in Bluff Siding, on the Mississippi River.

The route uses multiple types of existing bicycling infrastructure, including:state and county bike trails, local roads and bike paths, state and county highways.

USBR 230 is an alternate leg, providing routing directions for use when the Merrimac Ferry (Colsac III) is not in operation.
