Muddy Creek Bridge
Muddy Creek Enclosure, City of Arnold, Missouri This civil site development project was for a new Walgreen's Pharmacy and included: design of the parking lot with ADA accessibility, curbs and gutters, onsite stormwater infrastructure, paving, sidewalks, lighting, street entrances and utility extensions. A major part of this project included enclosure of Muddy Creek, which traversed across the lower segment of the project’s site.
In order to accommodate City site parking space requirements, approximately 180 feet of Muddy Creek was enclosed, with the structure designed to pass the area’s 500-year design storm. Because the creek was located within a floodway, the project required a nationwide permit from the U.S. Army Corps of Engineers (COE) and approval by the Missouri Department of Natural Resources (MoDNR). Due to MoDNR stream disturbance limitations, the enclosure structure was constructed using pre-cast / pre-stressed concrete box beams, with reinforced concrete cap beams sitting on top of steel sheet piling walls. Use of a steel piling eliminated the need for excavation below the stream’s ordinary high water level. The enclosure width was 30 feet, with a length of 180 lineal feet. The bridge was designed for AASHTO HS-20 loading and was privately funded.
