City of Redwood Falls, Minnesota
The southern portion of Gould Street was severely weathered but showed no evidence of base failure. The northern portion required both utility improvements and pavement restoration. The challenge was developing a solution that accomplished the needed roadway and utility improvements while maintaining access to the adjacent facilities, including the Redwood Area Hospital. Meetings were held with the hospital to ensure continuous access and utility service during construction, and uninterrupted use of the hospital heliport.
After analyzing existing roadway conditions, utilities, and several improvement options with city staff, a mill and overlay of the southern portion and a full-depth reconstruction of the northern portion of the roadway was selected, including full reconstruction of the existing underground utilities. To maintain continuous water service to the hospital, the existing watermain was kept in place while a new watermain and water service could be constructed, pressure tested, and disinfected. A short-term potable water supply was set up for the temporary connection of the new service. The water service to the hospital was completed without any interruption in service.
