Oklahoma State Highway 199 - Route Description

Route Description

The highway's western beginning is at I-35 exit 31 in Ardmore. At this cloverleaf interchange, eastbound US-70 joins southbound I-35 in a concurrency. SH-199 continues the alignment of US-70 along W. Broadway Street into Ardmore. At Commerce Street, the highway intersects US-77. SH-199 continues east along Broadway into downtown, where the highway splits along a one-way pair; westbound SH-199 follows W. Broadway, while eastbound traffic is shunted onto W. Main Street. SH-199 turns north along Washington Street and follows it to Sam Noble Parkway, where it turns back to the east. As it leaves town, it serves as the eastern terminus of SH-142.

After leaving Ardmore, the highway continues along a due east course that takes it through the unincorporated places of Dripping Springs and Caldwell Hill. At Dickson it becomes concurrent with US-177. Shortly after this junction, the two highways cross into Johnston County, where they pass through the town of Mannford. The routes then turn southeast into Marshall County. Just after the county line lies the southern terminus of SH-1, which leads back into Johnston County.

US-177/SH-199 continue southeast into Madill, the county seat of Marshall County. On the north side of town, they meet US-70; this point is the southern terminus of US-177. SH-199 continues along US-70 to US-377/SH-99, where it heads back east. SH-199 splits off on its own as it leaves Madill.

SH-199 continues east, passing through the unincorporated settlement of Little City. It then crosses over the Washita River arm of Lake Texoma. The highway then passes the Fort Washita historic site before ending near Brown, Oklahoma at SH-78.
