"Texas Crossings" (no culverts) and they have lasted for years with minimal repair and much over-flooding, and the road is fairly 'high-speed'. There

the A-- to maintain in the desert, and they almost always plug-up and overflow in flash-flood conditions, often ruining the road bed above them.
Just my 2-cents.
