Bridge aesthetics

On my way back from a recent trip, I travelled through Albuquerque by car. Over the years, they have been widening and rebuilding a stretch of I-40 in the city, which includes several bridges over the interstate. I snapped pictures of most of the aesthetic bridge elements I saw along that several mile-long stretch of road. There is always the debate of whether artistic/aesthetic elements should be added to a bridge or whether the bridge structure itself should be the art - I have to admit I do believe that first and foremost, the bridge structure should aim to be the artwork (I am particularly fond of arch wall bridges). But, if that is not feasible and there is opportunity to add elements to a standard bridge structure, it can be a great way to make it more interesting and inviting to the travelling public (maybe even educational or a public art opportunity) - only if done very judiciously. Decide for yourself which of these you like or don't like...!
