Construction began on January 6, 2025. It is expected that construction will take approximately five months to complete. Work hours will be 7 a.m. to 6 p.m., Monday through Friday, and Saturdays if needed.

What's Happening Now

The City’s contractor is using open trench excavation. Open trench excavation consists of digging down to and exposing the existing pipe, removing and replacing it or repairing it in place, backfilling the trench, and then apply a temporary asphalt patch. Permanent pavement restoration of the disturbed area will occur after construction is complete.
