SR 180 has its western terminus at a T-intersection with SR 159 nearly {{convert|5|mi|km}} northeast of Chillicothe. Its eastern terminus is at a diamond interchange with the U.S. Route 33 (US 33) expressway approximately {{convert|3.75|mi|km}} northwest of Logan. Route descriptionAlong its path, SR 180 travels through northeastern Ross County, the extreme southeastern corner of Pickaway County and the northwestern part of Hocking County. No portion of this highway is included within the National Highway System (NHS). The NHS is a network of routes determined to be most important for the economy, mobility and defense of the nation.[4] {{Expand section|date=June 2011}}HistoryThe SR 180 designation was applied in 1927. Prior to this time, the stretch of highway that SR 180 currently occupies through Ross, Pickaway and Hocking Counties was designated as SR 27. With the designation of the US 27 in that year, SR 27 was replaced by SR 180. The only change related to SR 180 since its inception has been the highway that it meets at its eastern terminus, which at the time was the predecessor to US 33, SR 31.[5][6] Major intersections{{OHinttop|length_ref=[1][2][3]}}{{OHint|county=Ross |cspan=2 |ctdab=Ross |location=Green Township |mile=0.00 |road={{jct|state=OH|OH|159|city1=Chillicothe}} |notes=Western terminus at T-intersection}}{{OHint|location=Adelphi |mile=11.79 |road={{jct|state=OH|OH|327|dir1=South|name1=Concord Street|road=Main Street|location1=Tar Hollow State Forest}} |notes=Northern terminus of SR 327}}{{OHint |county=Pickaway |ctdab=Pickaway |location=Salt Creek Township |mile=12.44 |type=concur |road={{jct|state=OH|OH|56|dir1=West|city1=Circleville}} |notes=Western end of SR 56 concurrency}}{{OHint |county=Hocking |cspan=5 |location=Laurelville |mile=13.09 |type=concur |road={{jct|state=OH|OH|56|dir1=East|name1=Pike Street|road=Water Street}} |notes=Eastern end of SR 56 concurrency}}{{OHint |ctdab=Hocking |location=Perry Township |mile=20.39 |type=concur |road={{jct|state=OH|OH|374|dir1=South}} |notes=Western end of SR 374 concurrency}}{{OHint |ctdab=Hocking |location=Laurel Township |lspan=2 |mile=25.01 |type=concur |road={{jct|state=OH|OH|374|dir1=North}} |notes=Eastern end of SR 374 concurrency}}{{OHint |mile=25.51 |road={{jct|state=OH|OH|678|dir1=South|city1=Gibisonville}} |notes=Northern terminus of SR 678}}{{OHint |ctdab=Hocking |location=Falls Township |mile=29.55 |road={{jct|state=OH|US|33|city1=Athens|city2=Columbus|CR|33A|county2=Hocking}} |notes=Interchange}}{{OHintbtm|keys=concur}} References{{Attached KML|display=title,inline}}{{Portal|Ohio|U.S. Roads}}1. ^1 {{cite web |url=http://www.odotonline.org/techservapps/SLD/pdf_files/rossr0180r.pdf |title=Technical Services Straight Line Diagrams: SR 180, Ross County |author=Ohio Department of Transportation |accessdate=2011-06-02}} 2. ^1 {{cite web |url=http://www.odotonline.org/techservapps/SLD/pdf_files/picsr0180r.pdf |title=Technical Services Straight Line Diagrams: SR 180, Pickaway County |author=Ohio Department of Transportation |accessdate=2011-06-02}} 3. ^1 {{cite web |url=http://www.odotonline.org/techservapps/SLD/pdf_files/hocsr0180r.pdf |title=Technical Services Straight Line Diagrams: SR 180, Hocking County |author=Ohio Department of Transportation |accessdate=2011-06-02}} 4. ^{{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=2011-06-01}} 5. ^1 {{cite map |title=Map of Ohio Showing State Routes |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1926a.sid |format=MrSID |publisher=Ohio Department of Highways and Public Works |date=August 1926 |cartography=ODHPW |accessdate=2011-06-01}} 6. ^1 {{cite map |title=Map of Ohio Showing State Highway System |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1927a.sid |format=MrSID |publisher=Ohio Department of Highways and Public Works |date=June 1927 |cartography=ODHPW |accessdate=2011-06-01}} 4 : State highways in Ohio|Transportation in Ross County, Ohio|Transportation in Pickaway County, Ohio|Transportation in Hocking County, Ohio |
