NC State Troopers periodically saturate the stretch of I-40 between the East Asheville exit and Black Mountain. Marked and unmarked cars frequent the onramps and the three median cut-throughs on this stretch. If you see one in an agressive posture, expect to see more. I’ve seen as many as six either stopping someone or ready to in one pass through this nine-mile stretch. The speed limit for westbound 40 drops from 65 to 60 about a mile to the east of the East Asheville exit. I’ve seen State Troopers sitting the wrong way on the off ramp at exit 55 to see people coming toward them that didn’t adjust for the slowdown. West of exit 55 the Asheville police sometimes work I-40 heavily as well.
