Question: At what junction on U.S. Ohio state Route 320 allows acces to Interstate 70?
Context: 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. State Route 209 (SR 209, OH 209) is an east–west state highway in eastern Ohio, a U.S. state.  The western terminus of State Route 209 is at a T-intersection with State Route 83 approximately 3.75 mi north of New Concord.  State Route 209's eastern terminus is concurrent with the northern terminus of State Route 821 at Interstate 77 at its exit 41 in Byesville, just 2.25 mi southeast of the Interstate's interchange with Interstate 70. Pennsylvania Route 320 (PA 320) is a north–south state highway in southeastern Pennsylvania.  The southern terminus of the 18.8 mi long route is at PA 291 in Chester.  The northern terminus is at PA 23 in Swedeland.  The route passes through suburban areas in Delaware and Montgomery counties to the west of Philadelphia, serving Swarthmore, Springfield, Broomall, Villanova, and Gulph Mills.  PA 320 intersects many important highways including U.S. Route 13 (US 13) and Interstate 95 (I-95) in Chester, US 1 in Springfield, US 30 in Villanova, and I-76 in Gulph Mills.  PA 320 runs parallel to I-476 (Blue Route) for much of its length and crosses it four times.  Even though there are no direct interchanges between I-476 and PA 320, several roads that intersect PA 320 provide access to I-476. State Route 10 (SR 10) is a state highway located in and around Cleveland, Ohio.  The current routing of SR 10 was certified in 1934.  The route's western terminus is in Eaton Township in Lorain County at the junction of U.S. Route 20, State Route 57 and State Route 301, where US 20 and SR 301 continue westbound on the freeway.  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.  It then continues through the western suburbs of Cleveland and through the western part of Cleveland, as Lorain Avenue, terminating shortly after it crosses the Cuyahoga River at Gateway at Broadway Avenue/Ontario Street (U.S. Route 422, State Route 8, State Route 14, State Route 43, and State Route 87). Interstate 470 (I-470) is a 13.72 mi loop highway that bypasses the downtown area of Topeka, Kansas.  I-470 begins at an interchange with Interstate 70 in western Topeka and heads generally southeast, running concurrent with U.S. Route 75 (US-75).  The concurrency with US-75 ends 5.74 mi later at the Burlingame Road interchange.  I-470 becomes part of the Kansas Turnpike at its junction with Interstate 335.  From there, the highway heads generally northeast through the southeastern sections of Topeka.  After traveling 7.03 mi as the Kansas Turnpike, I-470 reaches its eastern terminus with Interstate 70.  The highway has annual average daily traffic values as high as 43,000 west of Gage Boulevard to as low as 10,370 near the eastern terminus with Interstate 70.  As an interstate highway, Interstate 470 is a part of the United States National Highway System.  The non-turnpike portions of the highway are maintained by the Kansas Department of Transportation, while the turnpike portion is maintained by the Kansas Turnpike Authority. State Route 88 (SR 88) is a highway generally running in an east–west direction in the northeastern portion of the U.S. state of Ohio.  Its southern terminus is in Portage County at Ohio State Route 59; at the intersection of Freedom Street with Main Street in Ravenna. Route 88 is labeled north-south southwest of US 422 and Ohio 528, and labeled east-west east of US 422 and Ohio 528.  Route 88 follows a northerly direction for a little more than a mile along Freedom Street, to the State Route 14 and State Route 44 concurrency bypass.  From here, the route heads in a northeasterly direction.  Its next intersection is with State Route 700, at the southern terminus of the latter route.  A quarter mile further to the northeast, Route 88 joins State Route 303 for about a half mile.  State Route 88 then continues northeast, crossing over Interstate 80 and The Ohio Turnpike, before turning due north as it enters Garrettsville.  Here, as South Street, the route intersects with State Route 82 (State Street), then becomes North Street before exiting the corporation limits. In the U.S. state of Ohio, Interstate 70 (I-70) provides access between Indiana and West Virginia. New York State Route 320 (NY 320) is an east–west state highway located within Chenango County in the central part of New York in the United States.  It extends for 3.55 mi from an intersection with NY 12 north of the city of Norwich to a junction with Tiffany Road in the town of North Norwich.  The road shifts from state to county maintenance at the latter junction, and NY 320's right-of-way continues northeast from Tiffany Road as County Route 29 (CR 29).  NY 320 was assigned as part of the 1930 renumbering of state highways in New York.
