The 1891 Water Main Under Shelby Park Runs on Southern Jefferson County's Summer Schedule

While digging out the old main in Shelby Park, Louisville Water inspector Dennis Pike's crew found the iron cradles that once held the pipe up off the ground. In the utility's video on the project's history, an archive photo from the 1890s shows those cradles carrying a four-foot pipe over Beargrass Creek and a pasture with cows in it. "So in over years, the city has been built up over this water main and everything's been elevated," Pike says in the video. "So at one point, it looks like the water main's out of the ground, but now 130 years later, it's 5-ft below ground."

Everything about the work that returns to Shelby Park this fall follows from that photo. The pipe came first and the neighborhood was built on top of it. Its job is to supply homes miles to the south, so Shelby Park gets construction from fall through spring and a break each summer. It moves slowly because 13 decades of other utility lines now sit around it.

Two crews, opposite ends, one meeting point

Louisville Water scheduled active construction to resume Monday, October 26. For the first time since the project began, the work leaves Oak Street. One crew starts near East Oak and South Clay. The other starts on East Kentucky Street between the Beargrass Creek bridge and Vine Street. The two will work toward each other until they meet.

Here is the full route Louisville Water lists for fall 2026 through summer 2027:

The utility's October update places the work "in the Shelby Park and Germantown neighborhoods" and expects the whole project to finish next summer. The project page carries the current detour map, and its route list matches the update.

Why the cones disappear every summer

This is the third fall in a row with cones on Oak Street, and the reason is in Shelby Park's own taps. The new 48-inch pipe will carry water from the Crescent Hill Water Treatment Plant to the Brook Street main. Louisville Water calls that line a vital connection that supplies "hundreds of thousands of people in southern Jefferson County." According to the utility, it is "a vital feed to the southern part of the county and to our Cardinal Hill Reservoir."

A transmission main that important can't be torn up when demand peaks. In 2025, Louisville Water said crews packed up in May because "Summer is a peak season for water users with watering lawns, filling pools, irrigation systems, and overall higher usage for things like showering and laundry." It happened again this year. The utility halted the work over the summer for "peak season" and reopened the blocks between Jackson and Clay streets for those weeks.

So the dig happens on Shelby Park's side streets in the cold months, when lawns and pools across the south end of the county need the least water.

The pipe size explains why this phase digs at all. Phase 1 started in July 2024 near 12th and Dumesnil streets in a different part of the city. Crews used sliplining, which pushes a new pipe through the old one, and that phase ran until summer 2025. Pike explained in Louisville Water's 2025 update that "a 42-inch pipe (used in Phase 1) unlike a 48-inch pipe just doesn't carry enough water to fit the demand going south." The original main in Shelby Park is itself a 48-inch pipe, so a new 48-inch line can't slide through it the way the 42-inch pipe did in Phase 1. On these blocks the old pipe comes out and the new one goes in.

Why a handful of blocks takes a whole winter

Back in 1891, nothing was in the way when the main went in. Today the ground around it is full of utilities that came later. Louisville Water says Phase 2 has been "slower and more complicated because of an abundance of other utilities' service lines in the area, including Louisville MSD sewer lines, which required extra attention."

Project engineer Michael Meyer described the job in the 2025 update. "We're coordinating with the utility companies – MSD and Louisville Gas & Electric – to thread this new pipe with the dig and replace, so that we can have the same capacity if not a little better than what we have now."

The pace shows in the numbers. By October 2025, after more than a year of work that included the faster sliplining phase, crews had installed a little over 5,000 feet of pipe. The July 16, 2024 Board of Water Works minutes show an approved project budget of $25,660,079 and a $13,865,050 contract bid from Garney Companies for Phase 2. Phase 2 alone accounts for more than half of the budget.

The neighborhood that grew over the pipe keeps turning up

Digging below the modern street means digging through earlier versions of it. Near Oak and Brook streets, Pike found a section of the original pipe stamped with its maker. As he told Louisville Water's blog, "The pipe indicates it was made in 1891. It (DL Long) was a local foundry here in Louisville; I believe from records U.S. Pipe bought that foundry out."

The route also follows an old streetcar line. Crews found wood, rail ties and a long piece of metal track along East Oak Street, one block from Toonerville Trolley Park, which used to be an amusement park and a streetcar destination. "We'll be following these trolley tracks all the way down Oak Street. It was major thoroughfare back in the '(19)30s and '40s," Pike said. WHAS11 reported the same finds.

The streetcar tracks went in above the 1891 main, and sewer and gas lines followed. Each of them now sits between the crews and the pipe they are replacing.

What the work zone means on your block

Here is what Louisville Water has told people living and working along the route to expect:

• Access: Local traffic can still get in on either side of a work zone. Local access may shift as crews move, so follow the posted signs.
• Parking: Street parking will be limited or unavailable in and around the active zone. Spaces come back once crews move past.
• Noise and dust: Pike said people in the zone may get periods of equipment noise, ground vibration and dust.
• Water service: The utility says you will not lose water service during construction. Meyer explained that homes are fed by smaller distribution lines that stay on while the large transmission main is replaced. Louisville Water also says no one has lost water service at any point in the project.

Getting to the usual stops

Most of the regular places in Shelby Park are still open. Getting to them just takes a little more planning.

Shelby Park is listed at 600 E. Oak St. That's the same street where the western crew begins, between Hancock and Clay. Metro Parks has owned the 16-acre park since 1907. It is open 6 a.m. to 11 p.m. and includes a community center, an inclusive playground, tennis courts and a walking path. On days when the curb along Oak is closed, it's easier to walk in or come from a side street.

Logan Street Market is at 1001 Logan St. Its main lot is diagonally across the intersection, on the northwest corner of Logan and Kentucky. That's close to the eastern crew's East Kentucky segment. The market says there is unmetered street parking around its building and 30-minute spaces at the Logan Street entrance. It also asks drivers to keep clear of the loading docks on St. Catherine alley.

The St Catherine is at 729 E. St. Catherine St., on a street that is part of the work route. Construction on the building started in 1876 as Saint Stephen's. It is now restored as an event venue, and its owners describe it as the second-oldest Episcopal church building in Jefferson County. The building is 15 years younger than the main. If you're hosting or attending an event there this winter, check the detour map before you send directions to guests.

Louisville Water expects to finish next summer. Until then, the project page is the most reliable place to check which blocks are open before you head out.
