The Delaware River Port Authority is a regional transportation agency overseeing the port that connects global trade via the Delaware River. To keep the port competitive and to preserve over 80,000 quality jobs it was necessary to deepen the river which allowed it to accommodate larger ships. In 2008, the agency became the local sponsor to undertake the tristate project along 103 miles spanning PA, NJ and DE. As Port Director, Melissa Grimm co-managed the $300 million, multiyear project, including all of its external relations and communications with a complex array of stakeholders. The port dredging was completed in 2020.
