US-81 as the primary regional corridor

U.S. Route 81 runs through the Duncan area, serving as the city's own primary north-south regional highway corridor -- Duncan does not sit directly on a major interstate, a real, disclosed distinction from several other Oklahoma Tier A markets documented in this project.

Genuine distance from major metros

Duncan's position in southwest Oklahoma keeps it genuinely distant from both Oklahoma City and Dallas-Fort Worth, reinforcing the city's own, distinct, locally self-contained economy.

A genuinely car-dependent city overall

Duncan remains genuinely car-dependent, without meaningful public transit -- confirm current, specific commute times directly for a target address.
