Highways and Navigation

The primary route is I-75 South from Detroit to Toledo, then I-475 to I-80 East (Ohio Turnpike) to I-76 East (Pennsylvania Turnpike) to I-70 East past Frederick. This mix of toll roads and freeways requires careful planning for fuel and toll costs.

• Toll roads: Ohio Turnpike (I-80/I-90) has tolls ~$15 for the section used; Pennsylvania Turnpike (I-76) tolls ~$25 cross-state.
• Fuel stops: Regular stations near exits every 20-30 miles; in remote PA/WV areas, gaps may be longer—fill up in cities.
• Rest areas: Frequent along interstates with restrooms and vending; full-service service plazas on toll roads with food and fuel.

Fuel and Route Economics

Gas prices vary: typically cheaper in Ohio (~$3.50/gal) than Pennsylvania (~$3.80/gal) and Maryland (~$3.70/gal). A mid-size car (25 mpg) will cost about $70-80 total for the trip.

• Cash savings tip: Use GasBuddy for cheapest stations; avoid turnpike plazas which mark up 20-30 cents/gal.
• EV charging: Tesla Superchargers in Toledo, Columbus, and near Frederick; CCS stations in most towns.
