Looking at a variety of maps, it seems that even in the flat states like North Dakota, Kansas, Nebraska, etc. even the straightest of roads has a bit of a jog in it after 30 or 40 miles, going off the straight and narrow a bit to avoid a gully, knob, wash, or uncommonly large anthill.
Can anyone point me to the longest continuously straight road in the US? How about the world? I suspect Australia ought to be good for some unveering distances.
North Dakota Highway 46, is supposedly the straightest of them all – plumb line straight – the longest straight road in America. It stretches across 123 miles of north Dakota prairie from Hwy 30 in the west to a nameless county blacktop just past I-29 in the east, a steady 20 miles south of I-94.

Yeah, but if you read more closely about that road, you get this: “its longest straight-as-an-arrow, lock your steering wheel and take a nap stretch – extends nearly 31 miles, from Gackle to Beaver Creek.”
Not really. Look where it encounters Interstates 74, 55 and 155: in each one of those, 136 splits out a suicide or left turn lane, causing the primary lane to deviate from plumb. Looks like those segments are too short together to merit any kind of record.
I was going to lobby for some 40-odd miles of Hwy 17 north of Alamosa Colorado just past the road to Sand Dunes NP, but it looks like the road has a very subtle wander to it.
