Encyclopedia
State Highway 112 is a 24.6 mi (39.6 km) state highway
in Le Flore County
, Oklahoma
. It connects Poteau
to Arkoma
. It has no lettered spur routes.
. The highway then clips the west edge of Cameron
. Northeast of Cameron, the road crosses over James Fork. In Rock Island
, Highway 112 serves as the western terminus of State Highway 120
. At SH-120, it turns more northerly and crosses Backbone Mountain
.
On the far side of the mountain, SH-112 passes through Pocola
. On the north side of town, the highway intersects US-271/SH-9. SH-112 joins the concurrency
, headed east. The road becomes a freeway in the run-up to Interstate 540
, which begins at the Oklahoma–Arkansas state line. SH-112 exits at the last interchange in Oklahoma. From here, the highway heads north toward Arkoma
, paralleling the state line.
SH-112 intersects SH-9A in Arkoma, and one of the two highways continues to the state line. Sources conflict as to which highway continues from this point, and the ultimate location of the northern terminus of SH-112. Signage present as of 2004 indicates that SH-112 continues north to end at the Arkansas state line, where no Arkansas highway exists to connect to it. However, the internal ODOT control section maps show SH-112 ending at SH-9A, and SH-9A ending at the state line. The Oklahoma state highway map distributed to the public is not detailed enough to include a label for the section of highway in question.
The most major change in SH-112's history came on February 5, 1973, when the highway was extended to Arkoma. One further straightening occurred in the Cameron vicinity on June 27, 1982. No further changes have occurred since then.

History
State Highway 112 was added to the state highway system on August 15, 1955. Originally, the highway was paved until just south of Cameron, then continued as gravel through Cameron, ending at US-271/SH-9 in what is now Pocola (the town is not shown on contemporary maps). On October 5, 1959, the highway was straightened between Cameron and US-271. By this time, the highway was entirely paved. Further straightening between Cameron and Rock Island occurred on June 1, 1970.The most major change in SH-112's history came on February 5, 1973, when the highway was extended to Arkoma. One further straightening occurred in the Cameron vicinity on June 27, 1982. No further changes have occurred since then.
