I posted that they should bring the idea to the forums, I'm sure others said the same thing in their votes. I hope they do so we can all hash it out.
I agree. The concept is worthy of at least a discussion, but their execution for this category was poor by being so generic. They left it too wide open for any old strip of sidewalk under a road. Not as bad as the oft-threatened "Crosswalk" category, but it could be a disaster if they do not place some limitations.
The limitations need to be developed with the thought of why this site should be visited (remember there are two parts to waymarking, posting and visiting). Is it architectually or artistically interesting? Is it historically significant? Is it a key link between other important sites or otherwise important like a trailhead?
The pedestrian underpass that I am most familiar with is the Museum Campus Underpass in Chicago which links up Grant Park with the Field Museum and its neighbors under Lake Shore Drive. Its width is large with some public art displayed under 8 lanes of traffic. Not as smelly as some of the locations Team Sieni is thinking of, but, yes, urine is a common smell.
