City seeks to stop erosion from claiming bridge, power lines

September 22, 2018

VICKSBURG, Miss. (AP) — Officials looking to rebuild a collapsed bridge in a Mississippi city have another problem — the underlying waterway is trying to change course.

The Vicksburg Post reports Hennessey Bayou began cutting a shorter channel to the Mississippi River after the river’s 2011 flood.

Engineers say river water that backed up the bayou and quickly receded undermined a bridge that collapsed in 2017. More erosion could undermine a second bridge, plus electrical transmission towers that carry power from an Entergy Corp. plant.

The U.S. Army Corps of Engineers is making a plan to stabilize the bayou’s bank. The city and the Corps are splitting the study’s $75,000 cost.

Vicksburg is seeking a $1.6 million federal grant to pay for stabilizing the erosion. Vicksburg and Entergy would pay for a $550,000 match.
