The Delaware River connects New Jersey, Pennsylvania and Delaware. It connects upriver habitats with the ocean. And it connects inland ports like Philadelphia’s with international commerce. But as much as the river connects, an effort to deepen it divides.

Today on Radio Times, Marty talks with MAYA VAN ROSSUM, the Delaware Riverkeeper who has led the environmental opposition to the dredging effort; and JOHN H. ESTEY, chairman of the Delaware River and Philadelphia Regional port authorities, the lead agencies sponsoring the much-delayed project.
