To use your own example, they're designed to handle a certain quantity of 18 wheelers but they're not designed to handle traffic that is entirely composed of 18 wheelers.

Raising the average vehicle weight from 1.5 to 3 tons will definitely have an effect.

But not as much as it would seem, since road damage is a quadratic function of weight and one truck does as much damage as 9600 1 ton cars. Doubling the weight of the car would maybe narrow that by a few percentage points, but vehicle miles for any personal vehicle at essentially any weight is a rounding error compared to one truck.

Bridges at least need to be designed for just 18 wheelers because over 50 years that’s going to happen at least once.
