Road Quality and Infrastructure Safety

I-95 is well-maintained but can be congested near urban centers. In Maine, US-1 becomes a two-lane road with frequent stoplights. Road quality in Acadia National Park is excellent but narrow. Winter conditions require all-season or winter tires. Cell service is reliable except in remote sections of Maine's Down East coast. Rest stops are plentiful along I-95, while US-1 offers scenic overlooks but fewer services.

• Road surface: Generally good; potholes possible in New York.
• Rest areas: Every 30-50 miles on I-95, fewer on US-1.
• Emergency services: Accessible via 911; cell coverage sporadic in Maine.
