Unbreakable Bridges
A new bridge design replaces
reinforced concrete columns
and bars with steel tubes
filled with concrete. The
steel and concrete bind,
creating strong yet supple
columns For the bridge

Blue Jean Insulation
A medical center is
insulating its walls with
recycled blue jeans instead
of fiberglass. The new
construction material is
more environmentally
friendly, as fiberglass
contains formaldehyde, which
