Gettysburg to Baltimore SR 140?

Thanks Busskipper and Terry25 for your comments, I just remember being stuck in a whole mass of traffic coming down 15 and 70, not sure which. I was thinking that even though 140 might be slower it might be faster than being stuck behind a mass of cars going nowhere. I guess when we get there I'll decide but going to Essex to see my daughter is our destination. I'm thinking of going over the east side of 695 to avoid the toll of the bridge and it drops right into the Essex area. When we leave we will then go over the Francis Scott key bridge to head south and home.
