SEH received the Grand Award for the 10th Avenue Bridge SE Rehabilitation in Minneapolis, Minnesota, and an Honor Award for the Morningside Avenue/CSAH 15 in Glencoe, Minnesota.
ACEC-MN’s Awards Program recognizes engineering achievements that “exhibit the highest degree of merit and ingenuity.” Entries were judged by an objective panel based on “uniqueness and/or innovative application of new or existing techniques; future value to the engineering profession and perception by the public; social, economic, and sustainable development considerations; complexity; and successful fulfillment of client/owner needs.”
SEH, Olson & Nesvold Engineers (ONE), and the city led a thorough rehabilitation project, including removing and replacing the entire deck of concrete arch span portion of the bridge. Project highlights include using a cathodic protection system to protect the bridge’s arch ribs and using tower cranes for construction. Multimodal improvements included reducing vehicle lanes from four to two and adding sidewalks and protected bike lanes, supporting the city’s commitment to reducing carbon emissions.
The project features include a new regional highway connection, a roundabout, water main replacement, improved drainage to address local flooding, a regional trail connection, and a new railroad crossing.
