sprjus4:
Both I-40 and US-421 (former Business 40) need to be 6 lanes between Winston-Salem and Greensboro with current traffic volumes.

Love2drive:
I figure it varies from state to state, but is there a AADT you would look for before a highway needs 6 lanes?  8 Lanes?   I was looking at the AADT's from 2019, and some of the numbers surprised me. I was surprised to see the stretch of 40 between Hickory and Conover ranged from 58,000 to 68,000.   Interstate 40 through Winston Salem ranged from 98-128,000.   Not sure if there has been any talk of widening that stretch to 8 lanes.

froggie:
There's far more variables than "whichever state you're in".  Things like truck percentage, directional distribution, hourly distribution, distance between interchanges, and many other factors.

ARMOURERERIC:
40 is very saturated in truck percentage
