The Krotz Springs Bridge are dual cantilever bridges in the U.S. state of Louisiana which carries US 190 over the Atchafalaya River at Krotz Springs. The original bridge, a truss span costing $1 million, was built in 1934 and carried two lanes of US 190 traffic. It was one of many bridges constructed in the early 1930s named the Long-Allen Bridge. In 1973, a parallel span was built to accommodate westbound traffic as traffic counts overwhelmed the original bridge. In 1985, the original span closed and was demolished, temporarily converting the 1973 span to two-lane traffic. The current eastbound span opened in 1988. In September 2015, the bridge was named for Frank and Sal Diesi (Wikipedia).
