Historic Properties

The Long Bridge is a contributing resource to the East and West Potomac Parks Historic District and is, therefore, a “historic property” for the purposes of Section 106 of the National Historic Preservation Act (NHPA). The Federal Railroad Administration (FRA) and the District Department of Transportation (DDOT) conducted a preliminary identification of other historic properties within or adjacent to the Long Bridge corridor, which extends approximately 3.2 miles from the Virginia Railway Express (VRE) Crystal City Station in Arlington, Virginia to Virginia Interlocking located near 3rd Street SW in Washington, DC. 

Section 106 of the National Historic Preservation Act (NHPA) Overview

Section 106 of the NHPA requires that Federal agencies consider the effects of their projects on historic properties. Historic properties are any prehistoric or historic district, site, building, structure, or object included in, or eligible for inclusion in the National Register of Historic Places (NRHP) maintained by the Secretary of the Interior.

The Advisory Council on Historic Preservation’s (ACHP) Section 106 implementing regulations in 36 CFR Part 800 define a four-step decision making process for compliance with Section 106. The four steps are:

  1. Initiate consultation;
  2. Identify properties that may be affected by the project, and determine if the property or properties are historic as determined by eligibility or listing on the NRHP;
  3. Assess the effects of the undertaking on historic properties; and
  4. Resolve adverse effects on historic properties by developing and evaluating alternatives that could avoid, minimize, or mitigate those effects.

The result of consultation could be a legally binding Memorandum of Agreement (MOA) or a Programmatic Agreement (PA).

Consultation Process

Section 106 of the NHPA requires Federal agencies to identify and consult with SHPOs, Tribes, and other consulting parties to avoid, resolve or mitigate adverse effects to historic properties.

Consulting Parties are:

  • Applicants for Federal assistance / approvals (for the Long Bridge Project: DDOT)
  • State Historic Preservation Officers (Virginia and District of Columbia);
  • Federally recognized Indian tribes / Tribal Historic Preservation Officers;
  • Local governments;
  • Advisory Council on Historic Preservation;
  • Other individuals/organizations with interest due to the nature of their legal or economic relation to the project or affected properties, or their concern with the project’s effects on historic properties (subject to FRA approval)

Potential roles of the consulting parties:

  • Discuss views
  • Help identify historic properties
  • Review pertinent historic preservation information provided by FRA
  • Help develop and consider possible solutions to avoid, minimize, or mitigate adverse effects to historic properties
  • Implement mitigation measures
