Interstate 68, western Maryland -- giant road cut through Sideling Hill Mountain
Appalachian Corridor E


A few of these highway projects have been extremely controversial due to severe ecological damage at great cost. Corridor H in West Virginia was fought by local opponents for many years (who ultimately lost their legal fight). One of their arguments is building a four lane expressway would divert resources away from maintaining existing roads, which will still be needed even with the new road. Corridor H slices through some of the most rural, steepest terrain in the eastern US and its construction cost was grossly underestimated by the highway department. Traffic levels on the completed segments have been very low.

Corridors B (I-26 in North Carolina) and E (I-68 in Maryland) have some of the deepest cuts of any roads in the US. Road construction is a form of "mountaintop removal" as permanent as stripping mountains to get the (increasingly thin) coal seams underneath. The Appalachians have some of the oldest geology on Earth. Destroying mountains for highways and strip mines are permanent alterations that will long outlast the fossil fuel era.
