The southern terminus of SR 621 is at U.S. Route 36 (US 36) approximately {{convert|2+1/2|mi|km|spell=in}} northeast of Coshocton, and its northern terminus is adjacent to the North Appalachian Experimental Watershed Station, just north of its intersection with White Eyes Township Road 188, about {{convert|5|mi|km}} northwest of the hamlet of Fresno. Continuing north after SR 621 ends is County Road 190 (CR 190). Established in the early 1940s, SR 621 is a two-lane spur route whose primary purpose is to provide access to the North Appalachian Experimental Watershed Station from the state highway network. The entirety of the route exists within Coshocton County. Route description{{tv-t|location=County Log Point|name=State Route 621|align=left}}{{tv-r|0.2|1,480}}{{tv-r|1.03|850}}{{tv-r|3.8|390}}{{tv-b|volume=AADT|source=[2]}}All of SR 621 is located within the confines of Coshocton County. This spur route is not included within the National Highway System.[3] SR 621 starts at an intersection with US 36 and CR 621 near the community of Canal Lewisville, with a sign saying "North Appalachian Experimental Watershed" along US 36.[4] The route moves northeast uphill, with hills on left of the route, and fields on the right. SR 621 intersects CR 193 at a Y intersection, and continues moving north. A mile (1.6 km) later, SR 621 turns east and bends around a hill. After two miles, the road turns northeast for slightly more than one mile. There, SR 621 moves north for less than a mile, and ends at CR 190. The experimental watershed is located there.[4][5] HistorySR 621 was first designated in 1941. Its routing originally consisted of the present segment of US 36 between its northern junction with SR 83 north of Coshocton and the current southern terminus of SR 621, and then the entire current length of SR 621 up to the location of the North Appalachian Experimental Watershed Station.[6][7] In 1962, US 36 was re-routed out of Coshocton and onto its current alignment that bypasses the city to the north, following the north side of the Tuscarawas River. Part of this re-routing resulted in the southern terminus of SR 621 being moved to its present location at US 36 northeast of Coshocton.[8][9] Major intersections{{OHinttop|length_ref=[1]|county=Coshocton}}{{OHint|ctdab=Coshocton |township=Keene |mile=0.00 |road={{jct|state=OH|US|36|city1=Coshocton|city2=Newcomerstown|CR|621|county2=Coshocton}} |notes=Southern terminus }}{{OHint |ctdab=Coshocton |township=White Eyes |mile=5.98 |road={{Jct|state=OH|CR|190|county=Coshocton}} |notes=Northern terminus at North Appalachian Experimental Watershed Station }}{{Jctbtm}} References{{Attached KML|display=title,inline}}1. ^1 {{cite web |url=http://www.dot.state.oh.us/Divisions/Planning/TechServ/TIM/Documents/DESTAPECnty/DESCOS.pdf |title=DESTAPE - Coshocton County |publisher=Ohio Department of Transportation |date=June 24, 2015 |accessdate=November 9, 2015}} 2. ^{{cite web |url=http://tims.dot.state.oh.us/TIMS/Map/MapViewer |title=Transportation Information Mapping System |author=Staff |date= |website= |publisher=Ohio Department of Transportation |accessdate=2013-12-06}} 3. ^{{cite map | title=National Highway System: Ohio | date=December 2003 | publisher=Federal Highway Administration | url=http://www.fhwa.dot.gov/planning/nhs/maps/oh/oh_Ohio.pdf | format=PDF|accessdate=2011-01-20}} 4. ^1 {{cite web|title=Directions to the North Appalachian Experimental Watershed (NAEW) |url=http://www.dnr.state.oh.us/Portals/12/education/temp_workshop/Directions%20to%20NAEW.pdf|publisher=Ohio Department of Natural Resources|accessdate=2013-12-06}} 5. ^{{Google maps|url=https://maps.google.com/maps?saddr=US-36+E&daddr=OH-621+E&hl=en&sll=40.370936,-81.792709&sspn=0.002387,0.005252&geocode=FRz4ZgIdUEAf-w%3BFSIFaAIdJfEf-w&t=h&mra=me&mrsp=1,0&sz=18&z=18|title=Ohio State Route 621|accessdate=2013-12-06}} 6. ^1 {{cite map |title=Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1940a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1940 |cartography=ODOH |accessdate=2011-01-20}} 7. ^1 {{cite map |title=Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1941a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1941 |cartography=ODOH |accessdate=2011-01-20}} 8. ^{{cite map |title=Official Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1961a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1961 |cartography=ODOH |accessdate=2011-01-20}} 9. ^{{cite map |title=Official Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1962a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1962 |cartography=ODOH |accessdate=2011-01-20}} 3 : State highways in Ohio|Transportation in Coshocton County, Ohio|U.S. Route 36 |
