From The Dirt:
"Over a three year period, there were 23 accidents, mostly involving jaywalkers. This is six times the national average for urban streets. As a result, one of the key goals was to improve the "accessibility and functionality of the crosswalk and bicycle path systems."
"While this redesign can achieve a whole set of "goods" like increasing pedestrian and bicyclist safety and creating a more artful urban landscape, it's also a real-life example of sustainable reconstruction in action."
According to one of the project's designers, "the textured and irregular appearance of the medians, which can be perceived as looking 'scary or dangerous' actually make pedestrians safer."
The project's supporters estimate that the release of 60 tons of Carbon Dioxide was avoided by reusing the construction materials, as opposed to transporting, disposing, and crushing it.
