The World's First Precast Network-Arch Bridge
Currently under construction in Fort Worth, Texas by Sundt Construction. The bridge is a series of 12 post-tensioned concrete arches, six on each side, which are the main structural elements. Each arch is 163 feet long and over 23 feet tall. While the new bridge will remain with four traffic lanes, it will be much wider to incorporate lanes outside the arches for pedestrians and cyclists.
The plan calls for building the precast arches off-site, with expected total bridge closure time of no more than 150 days.

A Paragraph to Ponder
From the Free Exchange column of the September 28, 2013 Economist - The Mission Millions:
"Between 2007 and 2012 the number of applicants for DI [disability insurance] shot up from 11.2 per 1,000 working-age people to 14. Unpublished research by Mary Daly of the San Francisco Fed, Richard Burkhauser of Cornell University and Brian Lucking, a graduate student, estimates that this rise in applications equates to 2.6 m people. Depending on how many of those applications are eventually awarded benefits, this could explain between 31% and 59% of the decline in participation among 16-to-64-year olds."
