We’re currently working in Zone 2.

Use Blankenbaker Lane to access these locations:

  • Knights of Columbus
  • Rivers Edge Road
  • Waterglen Place
  • Longview Lane
  • Boxhill Lane
  • Woodside Road
  • Rockledge Drive (following mid-week access changes from Lime Kiln Lane. See below for more information on Rockledge Drive.)

Use Lime Kiln Lane to access these locations:

  • Virginia Chance School
  • Rockledge Drive (access will change to Blankenbaker Lane mid-week. See below for more information on Rockledge Drive.)
  • Glenview Avenue

For the week of July 7:

  • Zone 2 (River Road between Blankenbaker Lane and Lime Kiln Lane) will be limited to local access only. There will be staggered barricades to provide residents with access where River Road intersects with Lime Kiln Lane and at Blankenbaker Lane.
  • Our active construction zone is moving further east this week (July 7 – July 13). See the map below for details. We will be working between the River Valley Club and Glenview Avenue. Note: This will impact the intersection of Rockledge Drive this week. At the beginning of the week, residents of Rockledge Drive should use Lime Kiln Lane for access. That access will switch to Blankenbaker Lane at some point during the week as our open trench moves past that intersection. Residents of Rockledge Drive should follow signage for current entry and exit access.
  • Work in Zone 2 is expected to last approximately three to six months. The entire project will continue through this year and into 2026. Our goal is to finish most of the work on River Road by next summer.

Work Zone 1 is open.

Here’s how to access roads, businesses, and parks located in this zone.

You can take Zorn Avenue, Mockingbird Valley Road, Indian Hills Trail, or Blankenbaker Lane to River Road to reach these locations:

  • Different Strokes Golf Center                Cox Park
  • River House                                              Thurman-Hutchins Park
  • Kingfish                                                     Louisville Turners
  • River Road BBQ                                       Waldoah Beach Road
  • Haymarket                                                Wagners Beach Road

  • Riviera neighborhood is accessible from River Road or Blankenbaker Lane

residual line map

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.
