Ameren Mississippi River crossing, Brown win ASCE section awards

SPRINGFIELD, Ill. — Ameren Transmission Co. of Illinois, Hanson Professional Services Inc. and Steven Brown, P.E., CFM, a civil engineer at Hanson’s Springfield headquarters, were recognized Sept. 27 during the 93rd Annual American Society of Civil Engineers’ (ASCE) Central Illinois Section Meeting and Banquet in Champaign.

Ameren’s 1.56-mile Herleman-Maywood Mississippi River crossing (HMX) in Quincy was honored with the Outstanding Civil Engineering Achievement Award, which recognizes a project that best illustrates civil engineering skills and represents a significant contribution to the profession and society as a whole. The crossing is part of the Illinois Rivers Project’s 375 miles of 345-kilovolt transmission line running from roughly Palmyra, Missouri, across Illinois to the Indiana state line that will help improve the reliability of Illinois’ and the nation’s electric grid and provide the capacity needed to support new generation, including renewable energy.

The HMX crossing has six latticed transmission towers, including three on the river side of flood protection levees, two of which are on islands. Hanson conducted a subsurface investigation, provided foundation designs for the transmission towers and designed land and river access needed for the crossing’s construction.

Hanson’s foundation designs addressed structural challenges including scour, ice, flooding and wind. The foundations’ all-steel tripod construction substantially reduced the project’s environmental impacts by precluding the need to produce and transport concrete.

Steven Brown, P.E., CFM

Brown received the Young Civil Engineer of the Year Award, which recognizes civil engineers who are 35 years old or younger for demonstrated leadership potential and significant engineering contributions. He served on the boards for the ASCE Central Illinois and West Branch sections. He was awarded the Central Illinois Section President Award in 2013 for serving on the board. In addition to ASCE, he is a member of the Association of State Dam Safety Officials, Illinois Association for Floodplain and Stormwater Management and Illinois Society of Professional Engineers.

ASCE is a professional organization and the oldest national engineering society in the United States. Founded in 1852, ASCE has more than 140,000 members worldwide.
