Street & Utility Improvements
This project encompassed eight downtown alley blocks over a single construction season. The improvements consisted of new underground telephone, cable and electric lines and converting the old overhead equipment. Sanitary and storm sewer mains were replaced or repaired. The full alley width was paved with new concrete. The project navigated narrow corridors and was staged to minimize disturbance to the public to create a revitalized look to the downtown business district.
