Major highways 
The busiest highway in the county is Interstate 35, which enters the county on the north at Goldsby on the McCall Bridge. It then parallels the Canadian River through the county seat, Purcell. It eventually turns southward and leaves the county at its border with Garvin County.
Another important interstate highway is Interstate 44, which runs through the northwestern part of the county. The H.E. Bailey Turnpike Norman Spur connects this highway to the US-62/US-277/SH-9 intersection.
SH-9 enters McClain County via the McCall bridge, duplexed with I-35, and immediately turns due west, running along the northern edge of Goldsby until its intersection with U.S. Highway 62/U.S. Highway 277 south of Newcastle, Oklahoma. From this intersection the three highways, continue southwest towards Blanchard and further on to Chickasha in Grady County.
County roads 
Like many counties, McClain County contains an extensive network of county-maintained roads. They form a grid with parallel roads generally placed 1 mile apart.
To dispel confusion and assist the small cities introducing new 9-1-1 systems, the county road system was recently renamed and signed throughout the county. East-west roads are numbered, with 100th St. located along the southern edge of the county, and the numbers gradually increasing toward the northern tip of the county. North-south streets are named, generally indicating the name of the road in the Oklahoma City grid that the county road best aligns with. (e.g. Santa Fe Avenue would, if extended northward, eventually connect with the street of the same name in Oklahoma City.)
According to the U.S. Census Bureau, the county, roughly triangular in shape, has a total area of 580 square miles (1,500 km2), of which 570 square miles (1,500 km2) is land and 10 square miles (26 km2) (1.80%) is water.
