Trip Plan
Given the 1 hour and 30 minute duration, you have plenty of flexibility in your departure time, though avoiding peak rush hour on the Capital Beltway is highly recommended. Since the entire trip is relatively short, you likely won't need a formal rest stop, allowing you to complete the 67.2 miles in one go. Keep your $11 fuel budget in mind, but ensure your tank is topped off before you merge onto the Harbor Tunnel Thruway to avoid needing to navigate off the main path for gas. Because the route is turn-heavy, double-check your GPS settings before leaving North Bel Air to ensure you are prepared for the complex interchanges ahead. Focus on steady pacing to manage the transition between local roads and the high-traffic interstate segments.

Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
9 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
1h 30m on the road
