Fuse our garbage bags into bike bridges?

In this morning’s mail, this intriguing find from Lynn Kisilenko: a plastic bridge, capable of supporting a battle tank, made almost entirely of recycled plastic bags.

Could it, she wonders, be converted to peaceful uses as a pedestrian bike bridge across False Creek, an idea that just won’t go away?

For this project, the US Army used “94 percent recycled materials including glass, vehicle bumpers and about 85,000 pounds of high-density polyethylene plastic. That’s equivalent to about 550,000 one-gallon plastic milk jugs which, laid end-to-end, would extend nearly 82 miles.”

Why not a bridge with recycled tanks?
