Assunpink Creek Daylighting

Assunpink Daylighting Project

Assunpink Creek Daylighting

Before emptying into the Delaware River, the Assunpink Creek has been re-engineered to flow underground through parts of downtown Trenton.  One of these underground segments, or culverts, exists between South Broad Street and South Warren Street.  The creek is visible throughout Mill Hill Park before passing under the South Broad Street Bridge and into the culvert until it returns to the surface after the South Warren Street Bridge.

The City of Trenton has been working with the United States Army Corps of Engineers to return this segment of the creek to the surface, a process known as “daylighting.”  While this project has been nearly a decade in the making, it is anticipated that construction may begin within the next year.
