Carmel announces phased water and sanitary-sewer upgrades in Merchants Square; businesses will stay open

The City of Carmel and Carmel Utilities announced a 13-phase plan to modernize water and sanitary sewer networks along segments of Keystone Way, AAA Way, Merchants Square Drive, Medical Drive and Range Line Road. The city says work is scheduled to begin at the end of October 2026 and will proceed in localized, segmented steps rather than broad closures (City of Carmel newsflash: https://www.carmel.in.gov/CivicSend/ViewMessage/message/302919 and https://www.carmel.in.gov/m/newsflash/Home/Detail/148).

City communications say businesses will remain open and accessible throughout construction and that clear detour signs will be posted in advance of each phase; the local outlet Current Publishing reported the first phase will upgrade infrastructure under Keystone Way just west of Keystone Parkway (Current Publishing: https://www.youarecurrent.com/2026/10/11/infrastructure-upgrades-to-begin-soon-at-carmels-merchants-square/). The city provided a media contact and a utilities customer service phone number for updates (Carmel CivicSend).
