Why would it be cheaper per area when it's got so much more load?

I was talking about width versus cost per area of bridge. There are fixed costs to building a bridge and bridges with longer spans usually cost more than bridges with shorter spans above a certain minimum span length. However, for width, you only need to pay the additional cost of making the bridge wider while the costs of building a bridge at all get spread across more area.
