I had often thought of travelling around the inside perimeter of Texas (also my state), when I was younger, and I liked travelling more than I do now (confirmed homebody). I mapped it out a long time ago, and I forget how many miles it came to, but it was enough to dissuade me of such a venture.
So, I just asked Google about "how long is the longest road route around the interior of Texas", and here is the response:
A definitive "longest route" around the interior of Texas cannot be determined because there is no single, agreed-upon route. The state's large size and complex road network mean a route's length would vary significantly based on the driver's specific path. However, a hypothetical route following Texas's borders would cover over 4,000 miles.
Several road trip concepts and long highways demonstrate the state's vastness:
The Texas Perimeter Drive: While a literal drive along the borders is not possible due to impassable areas along the Gulf Coast and Rio Grande, a road trip following a path near the state line is estimated to be over 3,000 miles. For context, this is longer than driving from Los Angeles to New York City.
Longest straight-line distance: The greatest distance across Texas from east to west is 773 miles, and the north-south distance is 801 miles. Driving a curved road route would add more mileage to those journeys.
Interstate 10: The drive along I-10, from the Louisiana border to the New Mexico border, covers 877 miles and takes over 12 hours of driving alone.
Longest U.S. Highway within Texas: U.S. Route 83 runs from the Oklahoma border to the Mexico border, covering 906.5 miles.
The Texas Historical Commission has markers indicating the state's geographical center, noting that from that point, it is 401 miles to the most southern point of the state and 412 miles to the most northern point. However, this measures straight-line distance, not driving routes.
