Originally occupied by theQuapaw tribe, the Quapaw ceded the area to the U.S. Government soon after theLouisiana Purchase in 1818. During the late 1820s and 1830s, the area was given to theCreek andSeminole tribes after theirforced removal from the southeastern United States. An agreement between the two tribes resulted in this area being part of the Seminole Nation, located west of the Creek Nation.
In 1866, these tribes were forced to cede the area to the Federal Government; the professed rationale was their siding with the Confederacy during theAmerican Civil War.[4] The area became part of theUnassigned Lands and was opened for white settlement on April 22, 1889.

Cleveland County is rather conservative for a county influenced by a college town. While most such counties swung heavily to the Democrats in the 1990s, Cleveland County has gone Republican in all but one presidential election since 1952, and last went Democratic for president in 1964. However, the county leans much less Republican than the state as a whole; in 2020,Joe Biden became the first Democrat to win more than 40% of the county's vote sinceJimmy Carter in 1976, only losing the county by 14 percentage points, compared to a 33-point loss statewide.
The Nance bridge allows travel time from Purcell (west side of the Canadian River) to Lexington (east side of the river) to be only three minutes by car, according to google maps. When the bridge was closed for emergency repairs, the same trip was 43 minutes when rerouted north to the nearest bridge, or one hour, four minutes when rerouted southeast to the nearest bridge.
The 1938 construction of this bridge enabled communities from West and Southwest (Byars, Cole, Dibble, Paoli, Pauls Valley, Purcell, Rosedale, and Wayne) side of the river to reach the communities on the East side of the river (Lexington, Slaughterville, and Wanette). Traffic using the bridge allows trade and commerce to freely flow in this retail trade area of southern McClain County, southern Cleveland County, Southern Pottawatomie County, and northern areas of Garvin County, and the eastern portion of Grady County. The bridge, rebuilt in 2019, features the same design elements with concrete post and wrought iron railings with protected turn lane and sidewalks.[24]
According to the Oklahoma Department of Transportation, "History was made Friday July 26, 2019 in Purcell and Lexington, just as it was more than 80 years ago when the two cities celebrated the grand opening of a new bridge connecting their communities. The new US 77 Purcell/Lexington James C. Nance Bridge that links the twin cities, located less than one mile apart, fully opened to traffic with much fanfare on Friday, July 26, 2019, the culmination of a major two-year, expedited reconstruction project."[24]
