State Route 320 (SR 320) is a short north–south state highway in western Ohio, a U.S. state.
 The southern terminus of SR 320 is at U.S. Route 35 (US 35) approximately 3 mi southeast of New Paris, 3/4 mi south of US 35's eastern junction with Interstate 70 (I-70).
 The northern terminus of the state highway is located in New Paris at a signalized intersection with SR 121.
State Route 29 (SR 29) is an east–west state highway in the west-central portion of the U.S. state of Ohio.
 Its western terminus is at the Indiana state line near Celina, where State Road 67 continues west.
 It continues east to St. Marys where it junctions with U.S. Route 33.
 In that town, it also crosses State Route 66, State Route 116, and State Route 703, which was its former alignment before a divided highway was built.
 After turning south it crosses State Route 219 in New Knoxville and then has an interchange with Interstate 75, continuing into Sidney where it meets State Route 47.
 Still going southeast, it briefly joins State Route 235 before turning east and then south again to enter Urbana.
 Here the route joins U.S. Route 36, and the concurrency intersects with U.S. Route 68 and State Route 54.
 From there, State Route 29 leaves U.S. Route 36 and continues to Mutual, intersecting with State Route 161, and State Route 56 shortly after; later, in Mechanicsburg, the route intersects with State Route 4.
 The route then intersects with State Route 38, U.S. Route 42, and Interstate 70 before reaching its eastern terminus at U.S. Route 40 on the western edge of West Jefferson.
Interstate 255 (I-255) is a bypass route of Interstate 55 near St. Louis, Missouri and with Interstate 270, it forms a loop around the city.
 Even though St. Louis is in Missouri, a majority of the route runs through Illinois.
 It shares its southern terminus with 270 at the junction with Interstate 55, 270 goes to the west and 255 goes to the east.
 US 50 joins I-255 at Lemay Ferry Road.
 It crosses the Mississippi River on the Jefferson Barracks Bridge, enters Illinois, and then turns north.
 There is a junction with Interstate 64, where US-50 breaks off and goes east, and then further north there is a junction with Interstate 55 again, Interstate 70, and U.S. Route 40, all of which are all co-signed together.
 The next junction is another one with Interstate 270, and it is the northern terminus of Interstate 255.
 After that, it becomes Illinois Route 255.

 In North Ridgeville, route 10 merges with Interstate 480 at the interstate's western terminus in North Ridgeville, and continues with the interstate briefly eastward.
 Just east of this junction, the route also has an interchange with Interstate 80 and the Ohio Turnpike via a connecting or spur road.
 SR 10 then becomes a grade-level road in North Ridgeville before heading into Cuyahoga County, and is known as Lorain Road.
