The southern terminus of SR 380 is at its junction with the concurrency of U.S. Route 22 (US 22) and SR 3 nearly {{convert|3|mi|km}} northeast of Clarksville. Its northern terminus is in downtown Xenia, following a brief concurrency with US 68, at the signalized intersection where the U.S. route meets US 42. Route descriptionAlong its way, SR 380 travels through the northwestern part of Clinton County and the southwestern quadrant of Greene County. No segment of SR 380 is included within the National Highway System (NHS). The NHS is a network of highways deemed most important for the economy, mobility and defense of the country.[2] {{Expand section|date=March 2011}}HistorySR 380 was assigned in 1935. Initially, it served as a spur route that ran along its present alignment from its current northern terminus in downtown Xenia southwest to the former northwestern Clinton County village of New Burlington.[3][4] Three years after its designation, SR 380 was extended to the southeast from New Burlington along a previously un-numbered roadway to its present southern terminus at the US 22/SR 3 concurrency near Clarksville.[5][6] Major intersections{{OHinttop|length_ref=[1]}}{{OHint|county=Clinton |cspan=2 |ctdab=Clinton |location=Adams Township |mile=0.00 |road={{jct|state=OH|US|22|OH|3|CR|4|name3=Creek Road|county3=Clinton|city1=Wilmington|location2=Cincinnati}} |notes= }}{{OHint |ctdab=Clinton |location=Chester Township |mile=3.54 |road={{jct|state=OH|OH|73|to2=yes|I|71|city1=Wilmington|city2=Waynesville}} |notes= }}{{OHint |county=Greene |cspan=2 |location=Xenia |lspan=2 |mile=17.67 |type=concur |road={{jct|state=OH|US|68|dir1=South|name1=Home Avenue|road=South Miami Avenue}} |notes=Southern end of US 68 concurrency }}{{OHint |mile=18.04 |type=concur |road={{jct|state=OH|US|42|US-Bus|35|US|68|dir3=North|name2=Main Street|name3=North Detroit Avenue|dab2=Xenia}} |notes=Northern end of US 68 concurrency }}{{OHintbtm|keys=concur}} References{{Attached KML|display=title,inline}}{{Portal|Ohio|U.S. Roads}}1. ^1 {{cite web |url=http://www.dot.state.oh.us/Divisions/Planning/TechServ/TIM/Pages/Straight-Line-Diagrams.aspx |title=Technical Services Straight Line Diagrams |author=Ohio Department of Transportation |accessdate=2011-03-13}} 2. ^{{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=2011-03-13}} 3. ^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/otm1934a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1934 |cartography=ODOH |accessdate=2011-03-16}} 4. ^1 {{cite map |title=Official Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1935a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1935 |cartography=ODOH |accessdate=2011-03-16}} 5. ^{{cite map |title=Official Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1937a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1937 |cartography=ODOH |accessdate=2011-03-16}} 6. ^{{cite map |title=Official Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1938a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1938 |cartography=ODOH |accessdate=2011-03-16}} 3 : State highways in Ohio|Transportation in Clinton County, Ohio|Transportation in Greene County, Ohio |
