State Highway 9, abbreviated as SH-9, OK-9, or simply Highway 9, is a major east–west highway in the U.S. state of Oklahoma. Spanning across the central part of the state, SH-9 begins at the Texas state line near Madge, Oklahoma, and ends at the Arkansas state line near Fort Smith, Arkansas. State Highway 9 is a major highway around the Norman area. At 348.1 miles (560.2 km), SH-9 is Oklahoma's second-longest state highway (second to State Highway 3).
From the western terminus at State Highway 203 along the Texas border, the highway travels due east for five miles (8.0 km) and intersects with SH-30 between Madge and Vinson. SH-9 continues east for 23 miles (37 km) without intersecting another highway until meeting US-283 and SH-34 two miles (3.2 km) north of Mangum. The highway overlaps the other two routes for four miles (6.4 km), going north, before splitting off and heading east again through Granite and Lone Wolf. East of Lone Wolf, the highway forms a concurrency with SH-44. Near Hobart, SH-9 overlaps US-183 for 4 miles (6.4 km)(again going northward) before splitting off again.
State Highway 9 (SH-9) is a state highway in Latah County, in the U.S. state of Idaho. It runs 13.522 miles (21.762 km) from SH-8 near Deary, north to SH-6 near Harvard.
SH-9 begins at an intersection with SH-8 near Deary and heads generally northwest and north to end at an intersection with SH-6 near Harvard.
The entire route is in Latah County.
SH-9 was the last State Highway in Idaho to be paved (though, as of 2012, SH-29 and SH-64 still have unpaved sections).
The Lewis and Clark Highway, from Lewiston eastward to Lolo Pass, was designated state route 9 in 1916 and construction began in 1920. Upon its completion in 1962, it became U.S. Route 12.
