Although the steel may be covered by concrete it is sometimes possible to see a series of lines running parallel to the direction of travel indicating where the metal is beneath (above) the concrete.
Luten strategically placed his steel in the areas under highest tension, e.g. the bottom of the highest part of the arch, saving weight.

I need to inspect this bridge closer when the leaves are off the trees, but I am curious if it might be a rare example of a Melan arch.
The Melan system used a series of parallel arched steel reinforcing, often small trusses. See fig. 5 here:
