This stretch of highway, in it’s entirety, is one long speed trap. Especially Winfield and Foley. Speed limits vary wildly, and change with very little notice, warning, or distance to decelerate. The towns along this highway use it strictly for revenue generation.
My wife was recently pulled over for doing 61 in a 60 (seriously). Take an alternate route if possible – it will be cheaper than losing a day in court to beat the bogus ticket.
