Highway History:
OK 37 has had the same route since at least 1953. However, there was once an OK 37A that ran along S.W. 119th St. in rural Oklahoma City and went from the Oklahoma/Canadian County Line to U.S. 62/U.S. 277.

Also, OK 37's eastern terminus was once at a state highway. Until the early 1990s, OK 77H ran along Sunnylane Road. The OK 77H designation was then moved a mile east to Sooner Road, and OK 37 was not extended east to the new OK 77H, so the highway now ends at an otherwise regular intersection in southeast Moore.

Highway Review:
OK 37 connects U.S. 281 in Hinton to the south Oklahoma City suburb of Moore. It is 2-lane for most of its journey. It joins OK 152 in the town of Cogar and the highways are co-signed for 11 miles, then OK 37 joins U.S. 81 for about a mile before going off on its own in Minco. OK 37 then heads east and widens to 4 lanes after going through Tuttle. OK 37 joins Interstate 44 for three miles, then it exits off and heads east along SW 134th St. in south Oklahoma City. Four and a half miles later the highway enters Moore, and crosses Interstate 35. Although not signed from Interstate 35, the highway continues east for almost three miles and ends at the intersection of SE 4th St. (which is the same as SW 134th St. in Oklahoma City) and Sunnylane Rd. in Moore. If the highway was extended just one more mile, it would actually end at a state highway, as OK 77H runs along Sooner Rd. a mile east of Sunnylane.

	OK 37 West at OK 4. At the time of this picture, this was the southern terminus of OK 4. The stoplights were not functioning, hence the stop signs; I just happened to take a picture while the light is red. So the truck in front of me is not running the red light - it had stopped. (Photo taken 10/4/02)
	Another view of OK 37 West at OK 4, taken six months later. Notice that both directions are now OK 4. The highway between Interstate 44 and OK 37 was completed in October 2002 and was signed OK 4 in March 2003. (Photo taken 4/11/03)
	OK 37 East at OK 76 between Tuttle and Interstate 44. This also serves as the northern terminus of OK 76. (Photo taken 8/24/02)
