This road used to be a 2-lane with blind driveways, and a 50 mph limit. Now it’s a 4-lane, wide-open blacktop with limited access and a 45. Every now and then the local constabulary gets "concerned about safety" and sets a trap. There are some pull-offs–farmer’s access–just south of 47th where a cop on a bike can be practically invisible as he sits in the late afternoon shade of the roadside trees. Also, as you approach Derby, around that last bend, there’s an as yet unused housing development entrance where the Derby police sit quite often, and can’t be seen until it’s too late. Speed limit drops to 40 right here, too, which most people don’t seem to notice.
