Spanning 483.9 miles, the drive from Post to Houston is a significant journey that takes approximately 7 hours and 49 minutes of pure road time. While it is technically possible to complete this trip in a single day, the duration makes it a long haul that requires stamina behind the wheel. You should budget around $72 for fuel to cover the distance comfortably. Because this journey takes you across the Great Plains, expect a consistent landscape throughout the transition toward the coast. Given the intensity of an eight-hour day, plan your schedule carefully to decide if you want to push through or find a midway point to break up the travel.

Trip Plan
To tackle this 483.9-mile route effectively, aim to depart early in the morning to maximize daylight hours for your navigation. Since the trip involves two planned stops, use these intervals to stretch and refuel, keeping your $72 fuel budget in mind as you monitor your gauge. The turn-heavy nature of the route means you should rely on a reliable GPS or map system to manage the transitions between West Main Street and Highway 84. Flexibility is your best asset here; do not hesitate to add a third break if the local road driving becomes fatiguing. Prioritize staying alert during the stretches on South Broadway Street, as the lack of highway miles means you will be encountering more frequent traffic shifts.
Morning Departure
Start early — leave by 6-7 AM to arrive at a reasonable hour.
Evening Departure
This is a long drive — plan for a morning departure or consider splitting it into two days.
This drive is better paced as a 2-day trip.
Plan roughly 2 meaningful breaks for fuel, food, and rest.
The halfway point lands around 246.6 miles from Post, TX, or about 4h 27m into the drive.

Consider an overnight stop or starting very early.
Departure
Before you leave
Start with fuel, water, and navigation already sorted so the first hour feels easy.

This is the best place for your longest stop, a real meal, and a full fuel check.
Overnight split
Day 1 wrap after about 246.6 miles or 4h 27m

Final approach
Final hour starts around 7h 49m

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
4 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 56m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.

More Details
What kind of drive is this?
Expect a turn-heavy, local-style experience rather than the predictable cruise of a major interstate. You will navigate through West Main Street, South Broadway Street, and Highway 84, keeping your focus sharp as you transition between these routes.

It is a practical, ground-level look at the Texas landscape that feels more like a local transit than a high-speed transit route.
95% highway — fuel and pacing are the main things to plan.
40 navigation steps total — most of the decisions cluster near the start and finish.
Longest single stretch: 137 mi on Texas State Highway 71.

Between Post, TX and Houston, TX, road signs point toward Sh 70 South, Sh 70 Business: Sweetwater, San Angelo and 71 Toll East.
Houston is a sprawling port city in Southeastern Texas. An oil boom and continuing international immigration has brought explosive growth to the city, and it is now the fifth largest metropolitan area in the United States and the most diverse large city since 2021. While at first glance, the city appears to be a 9-5 central business district surrounded by a sea of suburbs and strip malls, there are many hidden gems to be discovered.

The longest stretch is about 137 miles on Texas State Highway 71. The full list of main roads is in the Roads section above.
Yes — a 2-day pace is more comfortable than one long haul. A sensible stopping point is after roughly 247 miles on day one.
Expect about $1.23 in tolls one way, starting with 183A Toll Road. 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 Houston, 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 2 meaningful breaks. Dedicated rest areas are limited, so plan gas or food stops as your bathroom breaks.
The main spots that need attention: at 75.2 miles (US 84): Highway fork - watch signs carefully. Multiple destination signs - pick the right one; at 81.7 miles: Exit ramp - move to the correct lane early. Multiple destination signs - pick the right one; at 300.3 miles (183A Toll / 183A Toll Road): Highway fork - watch signs carefully. Lane positioning matters here.
Not recommended in a single day. At 8.9 hours each way, a round trip means 17.9 hours of driving — that is an unsafe level of fatigue for most drivers. Plan at least one night at Houston, TX before the return drive.
