State Trunk Highway 310 (often called Highway 310 or simply 310) is a state highway in the U.S. state of Wisconsin. It runs east–west in east central Wisconsin from near Manitowoc to Two Rivers. The nearly nine mile long road passes through mainly rural areas and intersects multiple County Highways along the way. The route came about in 1984 when US 10 was rerouted southbound with I-43 and County Highway D fell into state control.

Route description[edit]

Highway 310

Highway 310 starts at exit 154 of Interstate 43 and US Highway 10.[2] Highway 310 is a 4 lane highway for the first 0.3 miles (0.5 km) of its route.[2][3] It then continues as a 2 lane, rural highway.[2] The road then intersects County Highway R, which leads north to Rockwood.[2] Highway 310 then goes eastbound and crosses over the Little Manitowoc River.[2][4] At 2.6 miles (4.18 km) Highway 310 intersects County Highway Q in a relatively remote area.[2][3] Continuing eastbound the route continues through an area of marshland, and passes a large cemetery.[2][4] County Highway B is the next major road that Highway 310 intersects.[2] After this intersection the route progresses through more rural farmland with patches of forest in between.[2][4] After passing County Highway DD the road continues into a residential area in Two Rivers.[2] Wisconsin Highway 310 becomes a southbound residential street while in Two Rivers known as Hawthorne Avenue, and then turns back eastbound where it meets its terminus at Wisconsin Highway 42.[2]


In 1984 US Highway 10 was rerouted to run smoothly with Interstate 43, the former US 10 was designated State Highway 310. The remaining 7 miles of the road were part of County Highway D until the county government transferred the road to state control, and hence it became part of Highway 310.[1] This route has not changed since.[1]

Major intersections[edit]

The entire route is in Manitowoc County.
