US 158 West

Route
I 40 West, I 840 North, US 220 North, US 158 West, US 601 North, NC 801 South, I 40 West to Chapel Hill
Notes
US 601 north of I 40, NC 801 South and Farmington Road are marked with I 40 shields with a blue "Incident" banner over them. What is there between those the US 601 and Farmington Road exits that requires a permanent "Incident" detour?
The eastbound exit for NC 801 from I 40 goes into and out of a roundabout. The quadrant toward I 40 is blocked, so you cannot go all of the way around.
Results
US 158 is now complete from Merchant Mill Pond west. Connected US 601 from NC 801 to Mocksville.
