We’re done installing pipe on River Road!
Louisville Water’s residual line pipeline installation on River Road was completed in less than a year, well ahead of schedule. During the final phase of construction, workers will install valves in the new manholes and adjust final surfaces. This will involve closing one lane of River Road with the assistance of flaggers to direct traffic around these small work zones. The work will begin Monday, January 19 on River Road between Zorn Avenue and Transylvania Avenue.
This work is expected to last four weeks. To minimize traffic concerns, the lane closure will occur between 9:00 a.m. – 3:00 p.m.. The work will NOT impact access to restaurants, parks, or residences and no one will lose water service. When this work is completed, our contractor will return in the spring to complete restoration of unpaved areas and final cleanup efforts.
We greatly appreciate your patience and understanding as we work to complete this important project.

A Louisville Water project is underway to improve the reliability of our infrastructure.
Louisville Water’s filtration process produces residual solids that must be removed from the treatment plant. The residual line is the pipeline that takes the residuals from the Crescent Hill Water Treatment Plant to lagoons at our B. E. Payne Water Treatment Plant in Prospect. The system is critical to daily water production at Crescent Hill. The current line, built in 1971, is reaching the end of its useful life, so we are building two new lines for increased redundancy.
The project runs along Reservoir Avenue from our plant in Crescent Hill down Zorn Avenue, along River Road from Zorn Avenue to Transylvania Avenue, and along Transylvania Avenue to our property at the B.E. Payne Water Treatment Plant. The plan includes the installation of dual 24-inch residual lines.
In order to maintain the safety of the public and our crews, it will be necessary to close sections of River Road during construction of these mains. The construction along River Road will occur in four work zones. Only one work zone at a time will be closed. Detours will allow access to homes and businesses. When construction is completed in each work zone, the road will be paved and reopened as we move east.
