In Fort Worth, Texas, a dozen 20-foot-tall, 163-foot-long precast arches will make up what could be the first precast-concrete network-arch bridge in the world, according to officials of the Texas Department of Transportation. Off-site precasting "was a huge selling point" for the city, said Val Lopez of TDOT. The new bridge will replace the current one, built in 1913, which will be demolished once the arches are in place.
