AUTHORITY & DESCRIPTION: This project is authorized by Section 1135 of WRDA 1986, Environmental Restoration, and encompasses demolition and removal of a 500-foot buried concrete box culvert that currently contains a section of the Assunpink Creek between Broad and Warren Streets downstream from Mill Hill Park. The culvert roof has failed on two occasions and is a public safety hazard.  Day lighting of the stream will occur by completely removing the culvert roof, walls and floor, and exposing the stream to natural daylight and channel conditions.  Natural channel conditions are more conducive to aquatic habitat.  The new channel will improve anadromous fish migration by eliminating low-light conditions which disorient migrating fish and hinders their ability to spawn upstream. This reach of the Assunpink Creek was the site of the second battle of Trenton during the Revolutionary War and is immediately downstream of the historic Broad Street Bridge.

PROJECT GOALS:  The purpose of this project is to demolish and remove a 500-foot buried concrete box culvert to improve anadromous fish migration by eliminating low-light conditions. It also provides educational and cultural opportunities for the community as the site is the location of the Battle of the Assunpink Creek, known also as the Second Battle of Trenton during the American Revolutionary War in January, 1777.

STATUS: A $4.7 million contract for construction was awarded in August 2017 with completion expected in September 2018. Multiple contract modifications increased the contract value to $5.8 million and extended the completion date until September 2019. Partial funding for construction was provided by the New Jersey Department of Environmental Protection (NJDEP).
