They seem more than willing to add endless lanes to other big highways in Northern Virginia.
I'm guessing that I won't see a completed, four lane highway from I-81 to I-79 in my lifetime, so at the very least it would be nice to see some truck lanes added to the 2-lane portion of 48 between Strasburg and Wardensville.
But if the earlier poster is to be believed, adding these truck lanes may be tricky, depending on where the existing houses and businesses are.
I also cannot see at this point how they could possibly do the part between Wardensville and the state line given the terrain, but I'm also not a civil engineer.
