On my usual trek to NC, I noted some interesting markings along I-95 in South Carolina. Most lines are the usual quarter mile, but some are very close together and appear immediately after an overpass. I'm not aware of aerial enforcement but maybe I'm behind the times.
Here are the locations:
I-95 North: mile marker 24, 73, 111, 149
I-95 South: mile marker 151, 109, 99, 98 (short lines), 53, 29
Anyone see these or better yet seen them used in enforcement?
