Yep... I guarantee you it was a height issue...

And yep... It did ruin the aesthetic value of this bridge...

I just added a photo to the gallery of the bridge showing that the unique "link" railing has been altered. The railing was cut at about street level, a row of concrete blocks was inserted, and the original railing was placed on top of that.

I have to assume this was done to meet some standard for bridge railing height, but it ruined the aesthetic of this unique structure.

WOW!......This is the first I have seen (or heard) about this unique span.

Yes......It's definitely too organized to be graffiti. Looks more like a project that a local school or art class might have done. As long as it helps keep a 105 year old concrete bridge around.....I'm all for it.

Will have to check it out next time I'm in the area!

I'm not entirely sure, but it looks like too coordinated of an effort to be graffiti. I have vague memories -- someone correct me if I'm wrong -- that this bridge used to be painted in a more random color pattern.

Were the railings of this bridge painted by the owners or is it graffiti?
