Texas roads are basically their own mega-project at this point
Texas is huge, so it probably shouldn’t be surprising that keeping the state connected takes a massive amount of money, planning, and construction. Still, the scale of Texas transportation infrastructure is pretty wild.

Texas spends over $15 billion a year on transportation infrastructure, supporting highways, bridges, major road improvements, safety upgrades, and congestion relief. And considering how much Texans rely on roads to connect cities, ports, suburbs, small towns, ranchland, energy hubs, and rural communities, that investment touches just about everyone.
A few quick facts about Texas roads:
- Texas has about 325,684 centerline miles of public roads statewide.
- Those roads add up to more than 707,000 lane miles.
- Texas roads carry about 842.8 million vehicle miles of travel per day.
- Truck traffic alone accounts for about 95.8 million daily vehicle miles.
- TxDOT maintains roughly 81,180 centerline miles, while local and off-system roads account for about 244,504 miles.
- Texas has the largest bridge inventory in the nation, with 56,620 bridges.
- The average Texas bridge is about 44 years old.
- Texas also has 33 international highway bridges, helping connect the U.S. and Mexico.
- Proposition 7 helps fund non-tolled roads and transportation debt reduction through dedicated sales tax and motor vehicle tax revenue.
- TxDOT’s 2026 transportation plan includes more than $146 billion in projected investment over 10 years.
- A lot of that funding targets safety, congestion relief, rural corridors, major economic routes, and the state’s most congested roadways.
It’s easy to joke that Texas roads are “always under construction,” but with this much traffic, freight, population growth, and distance to cover, it kind of makes sense.
