The bank representing bondholders for the Garcon Point Bridge have filed a lawsuit seeking to force the state Department of Transportation to raise tolls to pay off construction bonds that are in default. The bridge opened in 1999, but neither the tolls nor the number of motorists using the bridge have been sufficient to pay off the debt from the bridge’s construction. The $3.75 one-way toll has not changed since 2011 and the lawsuit asks a judge to order the Department of Transportation to “upwardly adjust” the tolls.
