Well, seeing real life examples regularly - Warsaw has quite a few of them, one being near a major courthouse I visit occasionally - I'd say it is a bit on the small side. Still, there are at least three things that can be done with it, namely:
a) using styrene, it can be quite easily stretched and widened - I do not have pictures, but most bridges I've seen are at least twice as wide as this one, modern ones that is,
b) stairs from ground level to the first platform can be attached on both sides (needs two sets and a little surgery, but can be done),
c) different supports, especially concrete ones (for larger bridges that is a must) can be easily scratchbuilt. Plastic or metal tubes covered with Mr. Surfacer 500 will suffice, at least for rough concrete.
Other than that, looks like in terms of cheap and versatile diorama parts, Miniart takes the cake once again. And, my earlier comments on improving it notwithstanding, the bridge is a nice little kit. Pretty accurate, too.. there is a real world example standing next to the railway station in my wife's hometown. Heaven only knows how many times I've been walking on it back when we were dating.
