A dam, a bridge, an expressway, an interchange, flood control improvements, wastewater treatment and a dredged material containment embankment round out the 1990 Outstanding Civil Engineering Award nominees. Few tourists at Minnesota's Fall Lake notice the Fall Lake Reconstructed Dam, actually an enormous concrete wall hidden by large boulders and rock materials. The population of the area surrounding Jacksonville, Fla. grew throughout the 70s, but the transportation infrastructure did not. The Napolean B. Broward Bridge was the answer to the problem. To avoid flood devastation and the possibility of spending more than $14 million on damage repair, the city of Englewood, Colo. instead spent $8.6 million on an innovative flood control program, The Little Dry Creek Flood Control Improvements, a three stage, multi-purpose project constructed over eight years. The $550 million, 13.5 mi I-279/I-579 North Hills/East Street Valley Expressway opens a new era of modern transportation for Western Pennsylvania by linking downtown Pittsburgh with its northern suburbs. The Project 88 Wastewater Treatment Plant in Columbus, Ohio returned fishable swimmable water to the Scioto River. The $25 million Wilmington Harbor South Disposal Area Development project provided a dredged material containment embankment for the 1 million cu yd of material dredged from the harbor each year. It took 20 cranes and 130 workers 14 months to build the 80 ft high, five level, $61.5 million Interstate Highway 10/Sam Houston Toll Road Interchange.
