Not realistic. It wouldn't hold up in real life. The support wires have a lot of slack, so they would be purely aesthetic, thus leaving only the columns, which have high stress points, to support the thruout weight of the bridge, along with anything traveling atop it.. The bridge would sag and break in between the columns.
The blue is weird..
Other than the physical problems, which really aren't even an issue, it actually does look quite nice.
