Krotz Springs Bridge



This bridge is a K-truss bridge and is one of six bridges of this truss type in Louisiana. The K-truss type is virtually non-existent outside of Louisiana. -- Historic American Engineering Record

Completed in the summer of 1934 at a cost of about $1 million, its opening was delayed until April 13, 1935 as the connecting roadways had not yet been finished. Up to this time, auto traffic had shared the 1908 Missouri Pacific (now Union Pacific) Railroad bridge 1/2 mile downstream for the past five years. A few months after its opening, the bridge became part of both US 71 and US 190. (US 71 was cut back to the junction west of Krotz Springs in 1951).

The bridge was converted to carry only eastbound traffic after being supplemented by a new westbound span in 1973.

From January to April 1986, the bridge was demolished by Boh Brothers Construction Co. of New Orleans. It was partially dismantled, and the three steel spans were blown up in a series of explosions spaced a few weeks apart. The current eastbound span was then constructed atop the old piers and was completed in 1988.

Such a shame we've lost almost all of our K-Truss bridges.
