Jurisdiction FiledMarch 19th, 2012The City of Grand Island had two separate engineering firms’ complete studies on the condition and status of the Sycamore Street underpass which was built in 1950. These studies outlined some repairs and replacements which should be implemented to extend the life of the structure. Most issues needing to be addressed are related to the retaining walls of the structure as well as the South Front Street Bridge. The current storm sewer pumping system for the underpass is also outdated and in poor repair. The main purpose of this project is to do further geotechnical and structural analysis, analyze the recommendations, and to develop the most cost effective design to present to council prior to construction.
