[edit] Route description

[edit] Texas to I-35

SH-51 begins at the Texas line concurrent with US-60 just east of Higgins, Texas. It remains concurrent for 61 miles (98 km) until it reaches US-270/US-281/SH-3 at Seiling, Oklahoma. At Seiling, SH-51 joins with those three highways for nine miles (14 km) before splitting off on its own.

11 miles (18 km) after splitting off, Highway 51 meets SH-58 in Canton. It then continues east, crossing the North Canadian River and meeting SH-51A before turning northeast toward Okeene, where it intersects SH-8. SH-51 will go for 24 miles (39 km) before intersecting another highway.

In Hennessey SH-51 meets U.S. Highway 81 before continuing eastward. 17 miles (27 km) later, it meets SH-74 north of Crescent. 11 miles (17 km) to the east, it shares a brief concurrency with US-77; two miles later it has an interchange at Interstate 35, milemarker 174.

[edit] I-35 to Tulsa

After crossing I-35, SH-51 becomes a multilane highway and a major corridor linking I-35 to Stillwater, the home of Oklahoma State University. Along this 13-mile stretch is an intersection with State Highway 86. When Highway 51 reaches Stillwater, it meets US-177.

Continuing east from Stillwater, the road returns to a two-lane highway after sharing a one-mile concurrency with SH-108 and intersects with SH-18 eight miles (12.8 km) later. Four miles east of this, it passes through Yale, Oklahoma before crossing SH-99. It becomes a multilane highway again after a brief concurrency with SH-48. It passes through the small towns of Mannford and Lotsee on its way toward the Tulsa area.

[edit] Tulsa and beyond

In Sand Springs, SH-51 crosses the Arkansas River with SH-97 before merging onto the Keystone Expressway (U.S. Highway 412/U.S. Highway 64). When this freeway ends at I-244 near downtown Tulsa, Highway 51 merges onto I-244 southbound only to exit one mile later, where it overlaps US-64/US-75. This freeway is actually Interstate 444, but the interstate designation is not shown on signs. After one more mile, SH-51 leaves the interstate with US-64 and becomes the Broken Arrow Expressway, a freeway running northwest-southeast through Tulsa. US-64 leaves the freeway as a concurrency with US-169 southbound. Later, SH-51 will exit the freeway and become a four lane highway toward Coweta. The mainline freeway becomes the Muskogee Turnpike.

At Coweta, SH-51 turns back east after heading southeast through the Tulsa area. After crossing the Muskogee Turnpike again and bridging the Verdigris River the highway soon enters Wagoner, where it junctions with US-69. Returning once again to a 2-lane road, Highway 51 crosses Ft. Gibson Lake and the town of Hulbert. 11 miles later, it passes through Tahlequah, where it has a brief concurrency with US-62/SH-10. After spitting with these highways, it heads southeast toward Stilwell, Oklahoma, overlapping Route 59 for a mile on the way. After leaving Stilwell it provides access to Adair State Park, and then crosses the Arkansas line becoming Highway 244, which quickly connects to Highway 59.

[edit] History

SH-51 was originally commissioned on June 1, 1927 as a connector from Stilwell to Eldon at SH-27 (present-day US-62).^[2] By 1928, it had been extended to Tulsa.^[3] On June 15, 1933, it was extended to the east to the Arkansas state line, where it became AR-45.^[2]

ODOT extended SH-51 west to Stillwater and Perry (via a segment of roadway currently serving as US-177).^[2][4] On March 18, 1935, the section from Stillwater to Perry was rescinded and SH-51 was extended to SH-8 at Okeene.^[2][5] It was then extended to Seiling on October 18, 1938. On March 23, 1943, it was extended to the Texas state line by a concurrency with US-60.^[2]

The Broken Arrow Expressway was built in the early 1960s^[6] and opened in 1964.^[2] It was not, however, officially named the Broken Arrow Expressway until July 6, 1999 ^[7] by H.B. 1455.

[edit] Spurs

Like many in the Oklahoma state highway system, SH-51 has short spurs branching from it that bear the "51" number with a lettered suffix:

• SH-51A (23 mi/37 km) runs from SH-58 northeast of Canton to SH-8 near Roman Nose State Park. It is the longest suffixed highway in the system [1].
• SH-51B (18½ mi/30 km) connects Coweta to US-69 north of Muskogee. It goes through the towns of Porter and Tullahassee.
• SH-51C (decommissioned) (1.7 mi/2.7 km) connected SH-51 west of Stillwater to Carl Blackwell Lake until it was decommissioned in 2005.
• SH-51D (decommissioned) connected SH-51 south of Sand Springs with I-244 in Tulsa, running along Avery Drive and W. 21st Street. It appeared on some ODOT maps as late as the 1970s, but is no longer shown.^[8]
• In 2004, ODOT completed SH-51 Spur, running for 3 miles through Tahlequah to end at State Highway 82. It is currently the newest Oklahoma state highway. [2]
