Historic Roads

The preservation of historic roads is important to the preservation of national heritage and culture. Both governmental and non-governmental agencies have created programs intended to create an appreciation for and safeguard historic roads and the social history they embody. Examples of programs and projects in historic road preservation are listed below.

National Cooperative Highway Research Program (NCHRP) Web-Only Document 189: Design and Management of Historic Roads - This Transportation Research Board (TRB) document explores how the inherent flexibility in the current policies, manuals, criteria, rules, standards, and data sets that underlie the transportation planning and project development process may be used to preserve historic roads and roads in historic districts and settings.

The Lincoln Highway is a 3300-mile long road stretching across the United States from New York City to San Francisco. Its creation was the result of the first successful effort to build an all-weather transcontinental highway specifically for automobiles. Sites related to the Lincoln Highway include:

The Lincoln Highway Association is dedicated to preserving and promoting the Nation's first transcontinental highway for the automobile.
While the Lincoln Highway runs from coast to coast, Pennsylvania has designated a six-county region as the Lincoln Highway Heritage Corridor. The LHHC works to promote economic development through tourism grant programs and community beautification projects.

As the Dwight D. Eisenhower National System of Interstate and Defense Highways (Interstate Highway System) approached the fifty-year anniversary on June 29, 2006, large sections of the Interstate System would have achieved the mark at which resources are often evaluated for historic significance. In order to address the volume of administrative work this could foster, the Advisory Council on Historic Preservation adopted the Section 106 Exemption Regarding Effects to the Interstate Highway System on March 10, 2005.

This exemption effectively excludes the majority of the 46,700-mile Interstate System from consideration as a historic property under Section 106 of the National Historic Preservation Act (NHPA). In addition, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU, Public Law 109-59, Aug. 10, 2005) includes a provision (Section 6007) that exempts the bulk of the Interstate Highway System from consideration as a historic resource under Section 4(f) of the Department of Transportation Act. With these two exemptions in place, Federal agencies are no longer required to consider the vast majority of the Interstate Highway System as historic property under Section 106 and Section 4(f) requirements.

Excluded from these respective exemptions are elements of the Interstate System that are exceptional in some way or meet a national level of significance under the criteria for the National Register of Historic Places. The final list above identifies those elements that are not covered by the exemptions discussed above and will therefore continue to be subject to consideration under the Section 106 and Section 4(f) processes.
