technique is to inflate collapsible tubes and bend them into
arches. The tubes are filled with resin and concrete, which, the
researchers say, creates arches that are harder than steel. If it
works, the structures can be built faster, at a lower cost, with
greater durability, and look like other bridges. News of the
