Mendrop Engineering Resources, LLC was selected by the Mississippi Department of Transportation to evaluate the potential for scour and develop a plan of action at the bridge site on U.S. Interstate Highway 55 (I-55) Bridge #266.8A & B over Hickahala Creek in Tate County. The bridge scour evaluation study was performed in four phases, including hydrologic, hydraulic, and scour analysis and a geotechnical and structural assessment. Burns Cooley Dennis, Inc. was subcontracted to perform subsurface exploration at the site, while Amec Foster Wheeler (AFW) was subcontracted to perform the structural assessment. Mendrop then utilized the data and analysis to provide MDOT with a recommended plan of action.
