Hershey, PA to Bay City, MI: Epic Midwest Road Trip Guide

The route from Hershey, Pennsylvania to Bay City, Michigan spans roughly 610 miles, crossing five states: Pennsylvania, Maryland, West Virginia, Ohio, and Michigan. Driving time is approximately 9 to 10 hours without stops, but the journey offers far more than mere asphalt.

Notably, parts of this route trace the historic path of the Underground Railroad and follow the glacial ridges of the Allegheny Plateau. A local driving quirk: near the Ohio-Pennsylvania border, you'll encounter the steep, winding descent of Interstate 70 into Wheeling, West Virginia, where truck speed limits drop suddenly.

Infrastructure Safety & Road Quality

Pennsylvania and Ohio interstates are generally good, but sections of I-70 through Wheeling have narrow lanes and sharp curves. Construction zones are common in summer.

• Speed limits: 65-70 mph on interstates; 55 mph in urban areas.
• Tire chains required in snow zones in Michigan; not so in Ohio/PA.
• Emergency services: cell coverage good except remote stretches of PA 283.
• Rest areas: no overnight camping allowed at most, but truck stops allow RV parking.

Fatigue Management & Rest Zones

Plan stops every 2-2.5 hours. Key recommended rest points:

1. Flight 93 National Memorial (Shanksville, PA) – 20 min detour, sobering history.
2. Cuyahoga Valley National Park (near Akron) – easy hiking trails and restrooms.
3. Sandusky, OH – Cedar Point or just a lake overlook.
4. Toledo Zoo – quick walk through reptile house.

If tired, book a hotel at an exit in Ohio where rates are lower. Many have 24-hour coffee and free breakfast.
