State Highway 37 (abbreviated SH-37) is a designation for two separate highways in the state of Oklahoma.

The northern section of SH-37 runs 65.8 miles (105.9 km) miles from US-281 in Hinton to Sunnylane Road (former SH-77H) in Moore. The southern section of SH-37 is 12.54 miles (20.18 km) long.

Route descriptions

Central Oklahoma

The SH-37 in Central Oklahoma begins at US-281 in Hinton, Caddo County. It runs in a zigzag pattern for four miles (6.4 km) to the southeast before crossing into Canadian County. The Canadian County section runs in an irregular path to the southeast for 14 miles (23 km), before re-entering Caddo County.

Back in Caddo County, SH-37 runs three miles (5 km) south to the town of Cogar, where it joins SH-152, and turns to the east. This concurrency goes two miles (3 km) before entering Grady County.

In Grady County, SH-37/SH-152 goes 8.8 miles (14.2 km) to the east to US-81. There SH-152 turns to the north, and SH-37 joins US-81 for a one-and-a-half mile concurrency to Minco, where SH-37 splits off and heads east once again.

SH-37 runs for 16.6 miles (26.7 km) in Grady County, serving as the northern terminus for SH-92 on the west edge of Tuttle, and intersecting SH-4 in Tuttle before crossing into McClain County.

One mile into McClain County, SH-37 serves as the northern terminus for SH-76, then joins I-44 for a brief concurrency three miles later. SH-37 overlaps I-44 for three miles (5 km), running north across the Canadian River into Cleveland County and Oklahoma City, where it runs east along S.W. 134th Street into the city of Moore, where it becomes S. 4th Street.

SH-37 ends at Sunnylane Road, formerly SH-77H, in Moore.

Southeastern Oklahoma

The southeastern SH-37 begins where TX-37 crosses the Red River into Oklahoma, and heads north for two miles (3 km) to a junction with SH-98. At this point, SH-37 heads east for to its terminus at US-70 Bypass in Idabel.

History

Central Oklahoma

The portion of SH-37 in Moore between Janeway Avenue (just west of I-35) and its eastern terminus at Sunnylane Road was in the damage path of the EF-5 tornado that hit Moore on May 20, 2013.

Southeastern Oklahoma

The southeastern SH-37 was originally numbered as SH-57.
