Lima in Allen County, Ohio — The American Midwest (Great Lakes)
Wayne C. Gerdeman, P.E., P.S.
11-7-1945 to 8-18-2005
During Wayne's time at the Allen County Engineer's Office he supervised the replacement of 252 bridges, 59% of the bridges in Allen County. He personally designed 109 bridges, 44% of the bridges designed from 1967 thru 1999 in Allen County. Those 109 bridges represent 1 of 4 of the bridges in Allen County. The other 143 bridges he supervised during this time period were designed by ten engineers and consultants. He also designed many roadway projects in Allen County. During his tenure at the engineer's office, he hand-drew over 1500 detailed drawings, even after the use of computer aided drafting to prepare the drawings for a set of plans was the typical practice.
Some of the projects that Wayne designed and/or supervised include: the Metcalf Street Bridge Replacement over the Ottawa River, the Collett Street Bridge Replacement over the Ottawa River, the American Avenue Phase II Project, the Sugar Street Improvement Project, and the Cole Street & State Route 115 Intersection Improvement Project. As the Allen County Engineer Wayne was also instrumental in the planning and construction of the Eastown Road Improvement Project; this project widened the road from Elm Street to State Route 309 and extended the road from State Route 117 to Elm Street.
During Wayne's 5-year tenure as Allen County Engineer, he was responsible for reducing the number of bridges with weight limits or closed from 31 bridges in 2001 to 14 bridges in 2005, a 64% reduction. He was also able to secure over $21,000,000 in state funds and federal funds for bridge projects and roadway projects that were scheduled for construction from 2001 thru 2009.
Wayne has left his everlasting legacy on the transportation system of Allen County and will be forever remembered for his significant contribution to help increase the safety and improve the ease of travel for the motoring public on the county and township maintained bridges and roads within Allen County over his 37 years of service at the Allen County Engineer's Office.
