Trip Plan
With an estimated drive time of over 8 hours, splitting this trip into two days is the most sensible approach. Plan for two stops to break up the 397.3 miles, allowing for rest and refueling. Consider departing in the morning to maximize daylight for your first day of driving. The longest continuous stretch is 117.5 miles on NY 17, so ensure you have adequate fuel before embarking on that segment. Keep an eye on your fuel gauge, especially when transitioning between the Long Island Expressway and the New York State Thruway, as services can sometimes be spaced out on these major arteries.

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
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
6 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
8h 19m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.

Brookhaven is the largest town in Suffolk County, part of Long Island, New York. With 485,000 residents (2020). It includes a patchwork of villages and other communities, and is the only town on the island to touch both the Long Island Sound and Atlantic Ocean. The villages of Belle Terre, Bellport, Lake Grove, Mastic Beach, Old Field, Patchogue, Poquott, Port Jefferson, and Shoreham are semi-autonomous, and provide their own services in addition to those provided by the town. Other prominent communities include Mount Sinai, Stony Brook, and Fire Island, a long and car-free resort island off the south coast of the town.

Yes — a 2-day pace is more comfortable than one long haul. A sensible stopping point is after roughly 199 miles on day one.
Expect about $25.70 in tolls one way, starting with George Washington Bridge. 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 De Kalb, NY 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 2 meaningful breaks. Dedicated rest areas are limited, so plan gas or food stops as your bathroom breaks.
