The City of Carmel said it will replace aging water and sanitary sewer lines across parts of Merchants Square in 13 rolling, localized phases. Initial work will start under Keystone Way just west of Keystone Parkway and continue west toward the AAA Way/116th Street roundabout; clear detour signs will be posted and businesses will remain open.

Drivers should allow extra travel time and follow posted detours. For project updates, phasing maps and detour routes the city provided Carmel Utilities Customer Service at (317) 571-2442.

WHY IT MATTERS

This is a utilities upgrade announced by the City of Carmel to modernize aging water and sanitary sewer pipes in one of the city’s commercial hubs. Replacing old pipes is intended to strengthen reliability and allow the utility network to serve future growth in the Merchants Square area.

The project will be done in 13 rolling phases and the city says crews will work in localized, segmented steps rather than broad closures. That approach is meant to keep businesses open and limit traffic disruption, though drivers should expect temporary detours and slower travel through affected streets.

For people who live, work or run businesses in the Merchants Square corridor: follow posted detour signage, allow extra travel time during construction phases, and check the city’s phasing maps before you travel. The city listed Carmel Utilities Customer Service at (317) 571-2442 for updates and mapping; watch those official updates for the exact timing and boundaries of each phase.
