Amtrak and New Jersey Transit are partnering in constructing the Portal North Bridge, a two-track, fixed-structure railroad bridge across the Hackensack River to replace the century-old Portal Bridge. AKRF led the preparation of an Environmental Impact Statement and secured environmental permits for the project. These included permits and approvals from the U.S. Army Corps of Engineers, U.S. Coast Guard, New Jersey Department of Environmental Protection, and New Jersey Meadowlands Commission for substantial wetland and natural resource analyses, conceptual mitigation, Green Acres and parkland issues, contaminated materials investigations, and hydrology assessments. We also performed site selection and conceptual design oversight for the required tidal wetland mitigation for the project. AKRF contributed to all planning, design, and engineering phases of this $1.8 billion project.
