Take a left at the stop sign, and you're in downtown
Carney, such as it is.
This is, as near as I have been able to determine, the shortest signed state
highway in Oklahoma. The eastern terminus is only a quarter-mile from the
western terminus.
And if this is 40A, where's the parent road? Well, prior to it becoming
a US highway, US-177 existed as OK-40 from Ponca City to Warwick, nine miles
south of Carney. OK-40 existed as far back as 1935, according to my maps (but
not this far south; the PC-to-Warwick existed is shown on my 1953 map). By
1972 it was already US-177, so OK-40 was decommissioned sometime between '53
& '72.
