During the week of March 8, the Gowanus Remediation Team continued dredging activities along the canal, north of Union Street. We are pleased to report that this Phase 1 of dredging has been completed. Over the coming weeks our crews will begin the removal of aging timber batter piles and timber dolphins (protective barriers for bridges, bulkheads, and other canal structures) north of the Union Street Bridge. Once the piles and dolphins have been removed, dredging activities will resume, between the Carroll Street Bridge and the Third Street Bridge.

The dredged material is loaded from smaller “mini” hopper barges that can navigate the narrow canal to the transloading area at Huntington Street. The dredged material is then dewatered and transloaded to larger barges and shipped across New York Harbor to the dredged material processing facility in New Jersey.

The Carroll Street Bridge will remain in the open position while the New York City Department of Transportation (NYCDOT) performs maintenance on the bridge. Carroll Street will be closed to vehicular and pedestrian traffic until further notice.

Photos of construction activities are provided below.
