Route description
From its beginning at US-281, SH-11 travels east through the town of Capron. 9 miles (14 km) later, it reaches SH-8. SH-11 and SH-8 overlap for 7 miles (11 km), passing through the town of Burlington along the way. SH-8 / SH-11 meet SH-58 three miles (5 km) east of Burlington, and turn south, forming a three-route concurrency. The combined route passes through the unincorporated community of Driftwood and intersects US-64 just west of the town of Ingersoll. At this point, SH-11 turns to the east, leaving SH-8 and SH-58.
SH-11 passes through the northern part of Great Salt Plains State Park, and after 11 miles (18 km), intersects with SH-38. SH-11 continues on another seven miles (11 km), before intersecting with SH-132. Six miles to the east, SH-11's only spur route, SH-11A, branches off to the north, connecting to the town of Wakita. SH-11 travels another 11 miles (18 km) to the east, intersecting US-81 in Medford, the seat of Grant County. After leaving Medford, SH-11 runs another 10 miles (16 km) to the east, passing through Numa (unincorporated), before its junction with SH-74. From there, SH-11 heads east for 12 miles (19 km), passing through Deer Creek and running just to the north of Nardin (unincorporated), intersecting I-35 three miles (5 km) west of Blackwell.
SH-11 is four lanes divided for the three miles (5 km) to its junction with US-177 in Blackwell, then reverts to two lanes for the 12 miles (19 km) to its junction with US-77, six miles (10 km) south of Newkirk. Here, the route turns south, joining with US-77 for 3 miles (4.8 km), before turning back to the east 5 miles (8.0 km) north of Ponca City. After 12 miles (19 km), SH-11 passes through Kaw City, and crosses Kaw Lake, then runs another 13 miles (21 km) to SH-18, in Shidler.
SH-11 then joins with SH-18 for 9 miles (14 km), running south through the Osage County oil fields. Just east of Burbank, SH-11 leaves SH-18 for a 20 miles (32 km) concurrency with US-60 across the rolling Osage prairie to Pawhuska, the seat of Osage County. SH-11 then turns south on a five-mile (8 km) concurrency with SH-99, then turns back to the east, passing through more rugged terrain, through Pershing and Tallant (both unincorporated), before entering the oil town of Barnsdall 10 miles (16 km) later.
Just east of Barnsdall, SH-11 serves as the southern terminus of SH-123, which connects to Woolaroc Museum. SH-11 then heads roughly southeast, through Wolco (unincorporated), and skirts Avant, turning due south upon entering Tulsa County, before intersecting SH-20 on the east end of Skiatook.
After leaving Skiatook, SH-11 continues south as Cincinnati Avenue in Tulsa County, and 5 miles (8.0 km) later, doglegs a mile to the east at Sperry. SH-11 then resumes its path to the south as Peoria Avenue, passes through Turley (unincorporated), and enters the city of Tulsa at 56th Street North. SH-11 is a four-lane arterial street along Peoria Avenue, and at 36th Street North, turns to the east, going 1½ miles to US-75, the Cherokee Expressway. SH-11 briefly overlaps southbound US-75, then turns back to the east as the Gilcrease Expressway, passing by Tulsa International Airport before arcing back to the south. It then reaches its eastern terminus at I-244 / US-412 in east Tulsa.
