The route is generally safe with well-maintained highways. In winter, Pennsylvania's I-80 can be icy; check conditions via 511PA. New Jersey's Garden State Parkway has police patrols and speed cameras in some work zones.

• Pet-friendly framework: Most chain hotels along I-80 and Garden State Parkway allow pets; Best Western and Motel 6 often have no fee.
• Rest stops with designated pet areas: Sideling Hill Rest Area (I-80 westbound) and Ocean View Rest Area (Garden State Parkway southbound).
• Cuyahoga Valley National Park (Ohio) is a short detour and offers pet-friendly trails.

For families, consider these stops: Cleveland's Great Lakes Science Center (off I-80), Hersheypark (PA, near I-81), and the boardwalk arcades in Wildwood, NJ. Children's car seats are required by law in all states.

• Infrastructure: Road quality is excellent on the interstates; some rural two-lane roads in Pennsylvania's Amish country are narrow but paved.
• Hidden off-route spot: The abandoned Pennsylvania Turnpike tunnel (Breezewood area) can be accessed via a short walk from the I-76/I-70 interchange.

Fatigue management is critical for this long drive. Schedule two drivers or take a break every 100 miles. Caffeine and naps are more effective than loud music. Use the numerous rest stops on I-80 for power naps.

Start on I-94 East from Ann Arbor to Detroit, then merge onto I-75 South toward Toledo, Ohio. After Toledo, take I-80 East across Pennsylvania, which climbs through the Allegheny Mountains. In New Jersey, the Garden State Parkway South runs the length of the state to the Cape May exit.

• I-80: Pennsylvania's main east-west artery, with a speed limit of 65 mph; expect steep grades near the Delaware Water Gap.
• Garden State Parkway: 65 mph speed limit, but traffic can slow near exits; tolls collected electronically (E-ZPass recommended).
• Delaware Memorial Bridge: $5 toll for cars (northbound only; southbound free).

Fuel costs average $40-$50 per fill-up, with stations plentiful every 20-30 miles except in rural Pennsylvania. Gas prices tend to be lower in Ohio and higher in New Jersey.

For fatigue management, plan to stop every 2-3 hours. Rest areas are well-signposted on I-80 (Pennsylvania rest plazas with restrooms and vending) and the Garden State Parkway (full-service plazas with food and fuel).

• Tip: Download offline maps before entering Pennsylvania's remote areas with limited cellular coverage.
• Parking is abundant in Cape May, but beach-area lots fill quickly in summer; book accommodation with parking.

The route passes through three distinct eco-regions: the Great Lakes basin (Michigan/Ohio), the Appalachian Plateau (Pennsylvania), and the Atlantic Coastal Plain (New Jersey).

• Allegheny National Forest: Detour north from I-80 near Clarion, PA for dense hardwood forests and the Kinzua Bridge Skywalk.
• Delaware Water Gap National Recreation Area: At the PA/NJ border, this scenic area offers hiking, waterfalls, and the famous Kittatinny Ridge.
• Cape May itself boasts a bird observatory and pristine beaches in the Cape May National Wildlife Refuge.
