Two existing structures on County Highway 7 (north of Bruce, SD) had reached the end of their serviceable life and required replacement. Banner’s team performed the initial site surveys and hydraulic analyses to determine replacement structure types and sizes. After the replacement structure types and sizes were selected, Banner performed the final design of the replacement structures and preparation of the construction plans, including approach grading and guardrail.
