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
4 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

More Details
What kind of drive is this?
Prepare for a drive that shifts from busy urban infrastructure to a more turn-heavy, local experience as you progress. You will spend a significant portion of your time transitioning off the main interstate corridors, meaning this is not a monotonous highway grind. Because the route relies on local roads rather than a high percentage of highway travel, you should stay alert for changing speed limits and curves. The road requires more active focus than a standard freeway cruise, so be ready to adjust your driving style once you exit the major interstates.
89% highway — fuel and pacing are the main things to plan.
22 navigation steps total — most of the decisions cluster near the start and finish.
Longest single stretch: 174.9 mi on Katy Freeway.

Houston is a sprawling port city in Southeastern Texas.

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.
