The primary route is I-70 E from Indianapolis to the Hagerstown area, then US-301 S to the Chesapeake Bay Bridge, followed by US-50 E to Cambridge. I-70 across Ohio and West Virginia is well-maintained with multiple rest areas every 30–40 miles.

• Road quality: Excellent on interstates; US-301 is a two-lane highway with some sections in fair condition.
• Alternative routes: I-76 and I-81 offer a northern bypass but add 45 minutes.

I-70 is generally safe but watch for deer especially at dawn/dusk in rural Ohio and West Virginia. Frequent rest areas with 24-hour security exist near Dayton and Columbus.
