Trip Plan
For this 635.4-mile drive, departing early in the morning is advisable to maximize daylight hours. Given the 10h 38m estimated duration, planning for 3 stops is a good way to break up the nearly 11 hours of driving. If you decide to split the trip over two days, aim to drive around 5-6 hours each day. This allows for more relaxed stops and a less taxing experience. Keep an eye on your fuel levels, as the estimated cost is $91, and plan your refueling stops accordingly, especially since much of the route is on non-highway roads.

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.
For long drives, weather on day two can matter just as much as conditions at departure, so check the whole travel window rather than only the first day.
Time zone
1 hour earlier
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
Road read
10h 38m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.

Expect about $0.56 in tolls one way, starting with Central Expressway. Most Northeast and Midwest toll agencies accept E-ZPass; in the West and Texas, transponders like TxTag or FasTrak apply. If you do not have a transponder, cashless tolling plates will mail a bill to the vehicle's registered address — usually with a surcharge, so a rental-car toll pass is often cheaper than paying by mail.
We did not find dedicated rest areas on this route. For a drive this long, plan bathroom and stretch breaks around gas stations, fast-food stops, or small-town downtowns — check the Nearby Places section for options.
It helps. This route has a higher-than-average number of complex decision points, which get harder in the dark. If the last hour of the trip is on surface roads or mountain grades, aim to arrive at San Elizario, TX before sunset when you can. Check the Trip Plan for departure windows that land you in daylight.
Only with planning. This is a long drive for kids — consider splitting it into two days rather than pushing through. Plan at least 3 meaningful breaks. Dedicated rest areas are limited, so plan gas or food stops as your bathroom breaks.
