I-495-& I270 Managed Lanes Study

National Capital Regional Office » I-495-& I270 Managed Lanes Study » Document List

The Federal Highway Administration (FHWA) and the Maryland Department of Transportation State Highway Administration (MDOT SHA), pursuant to the National Environmental Policy Act (NEPA) and Council on Environmental Quality (CEQ) regulations at 40 CFR 1505.2, prepared their Final Environmental Impact Statement (FEIS)/Final Section 4(f) Evaluation and Record of Decision (ROD) for the I-495 & I-270 Managed Lanes Study (Study). The Study evaluated alternatives to address roadway congestion within the project area. The FHWA ROD approved the Preferred Alternative, Alternative 9 Phase 1 South, as their Selected Alternative, which includes improvements that will construct two new high-occupancy toll (HOT) managed lanes in each direction along I-495 and I-270 within the Phase 1 South limits, also referred to as the Project in this document. The limits of Phase 1 South follow I-495 from the George Washington Memorial Parkway in Virginia, to west of MD 187 and along I-270 from I-495 to north of I-370 and on the I-270 east and west spurs. There is no action, nor any proposed improvements included at this time on I-495 east of the I-270 east spur to MD 5.

This ROD documents NPS's decision to authorize the use of land from the George Washington Memorial Parkway, Chesapeake and Ohio Canal National Historical Park, and Clara Barton Parkway for the Selected Alternative, Alternative 9 - Phase 1 South, as described in the FEIS published on June 17, 2022, and as described in the FHWA ROD. That authorization will occur through an NPS Special Use Permit and a Highway Easement Deed. In consultation with the NPS, FHWA and MDOT SHA identified and committed to specific avoidance, minimization, and mitigation measures to reduce the impact of the Selected Alternative on the three NPS units listed above. This approval is conditional upon implementation of these mitigation measures and commitments relating to NPS lands and resources, as well as those listed in the FEIS, the FHWA's ROD, Statement of Findings, Section 4(f) determination, and the Programmatic Agreement between the FHWA, MDOT SHA, NPS, Virginia State Historic Preservation Officer, the Maryland State Historic Preservation Officer, and the Advisory Council on Historic Preservation.

The decision made by the NPS and documented in this ROD resulted from consultation efforts throughout the NEPA process, as well as the process outlined in Section 106 of the National Historic Preservation Act of 1966, as amended, and Section 4(f) of the U.S. Department of Transportation Act. The NPS served as a consulting party for the Section 106 process and as an official with jurisdiction for Section 4(f). This ROD includes a brief description of the Study's purpose, need, background, the role of the NPS, the Selected Alternative, and other alternatives considered; a statement of the NPS decision and basis for the decision; impacts and measures to minimize and mitigate harm to resources; and an overview of public involvement and agency coordination in the decision-making process.
