BATON ROUGE- The Water Institute of the Gulf's headquarters will be a futuristic feat of glass and metal that's propped up above the Mississippi River. That's according to a rendering released Monday shows.
    
Construction of the $22 million headquarters, research and interpretative center will start later this year.
    
The building is one of many that will make up The Water Campus, a national and international hub of river and coastal research.
    
Two other buildings have already broken ground, and they will be the LSU Center for River Studies and the Coastal Protection and Restoration Authority.
