Implementation of All Highway Projects Affecting Historically Significant

WHEREAS, the Iowa Division of the Federal Highway Administration (FHWA), administers ongoing annual appropriations of Federal Highway funding to the Iowa Department of Transportation (Iowa DOT) and the Iowa DOT may choose to use some part of that funding for ongoing programs to reconstruct, rehabilitate and maintain the various segments of the Lincoln Highway in Iowa; and

WHEREAS, the FHWA has determined that as a whole the Lincoln Highway in Iowa does not retain a high degree of integrity; however, some segments of the original Lincoln Highway do retain a high degree of integrity regarding original road design, landscape and historic driving experience and are considered eligible for listing on the National Register of Historic Places; and

WHEREAS, the FHWA and the Iowa DOT has determined that the reconstruction, rehabilitation and maintenance projects may have an effect upon the historic segments of the Lincoln Highway; and

WHEREAS, the FHWA and Iowa DOT have consulted with the Advisory Council of Historic Preservation (Council) and the Iowa State Historic Preservation Office (SHPO) pursuant to 36 CFR 800.14 of Section 106 of the Historic Preservation Act (revised 2001); and

WHEREAS, the Counties and Cities responsible for the maintenance of the historic segments of the Lincoln Highway have been consulted and invited to concur in this Programmatic Agreement;

WHEREAS, the Lincoln Highway Association of Iowa is a recognized interested party in the rehabilitation and maintenance of the historic segments of the Lincoln Highway have been consulted and invited to concur in this Programmatic Agreement;

NOW, THEREFORE, the FHWA, Council, SHPO, and Iowa DOT agree that the federally funded undertakings affecting the Lincoln Highway shall be administered in accordance with the following stipulations to satisfy Section 106 responsibility.


FHWA will ensure that the following measures are carried out:


  1. The FHWA/Iowa DOT will maintain a list of all the segments of the Lincoln Highway corridor that are considered eligible for the National Register of Historic Places as they retain a high degree of integrity of original road design, landscape and historic driving experience as agreed upon by the Iowa SHPO. [Appendix A]
  2. For all federally funded undertakings on all the segments of the Lincoln Highway route, FHWA shall follow the normal Section 106 process in accordance with the existing Programmatic Agreement between FHWA, IDOT and SHPO for the normal Section 106 Process; however, for segments of the Lincoln Highway route that are considered not eligible for listing on the National Register of Historic Places, the undertaking's effect on the Lincoln Highway route will not be considered significant.
  3. Federally funded undertakings that affect segments of the Lincoln Highway, listed as National Register eligible, shall be administered according to the plan titled "Engineering Strategies for the Management of Historic Segments of the Lincoln Highway within the State of Iowa" developed by the parties of this agreement.


1. Personnel Qualifications - Iowa DOT shall ensure that all cultural resource survey work shall be carried out by or under the direct supervision of a person(s) meeting, at a minimum, the Secretary of Interior's Professional Qualifications Standards for archaeologists, architectural historians and historians. (40 FR 44738-9)

2. Late Discoveries - Any unanticipated discoveries of historic properties or archaeological sites encountered during implementation of an undertaking shall be dealt with according to 36CFR 800.13(b).

3. Protection of Human Burials - All human burials in the State of Iowa are protected by law. In the event that human remains or burials are encountered during archaeological investigations or construction activities, the FHWA shall cease work in the area, take appropriate steps to secure the site, and notify officials at the Burials Program at the Office of the State Archaeologist or the Iowa Department of Health.

If the remains appear to be ancient (i.e., older than 150 years), the burial is legally protected under Chapters 263B and 716.5 of the Iowa Code, and the Office of the State

Archaeologist shall have jurisdiction until the cultural affiliation of the remains can be determined and their disposition can be arranged in consultation with the American Indian Tribe determined to be lineal descendants, following the provisions of the Native American Graves Protection and Repatriation Act (25 U.S.C. 3001 through 3005). If the remains appear to be less than 150 years old, the burial is legally protected under Chapters 144.34, 566 and 716.5 of the Iowa Code and would fall under the jurisdiction of the Iowa Department of Public Health.

4. Monitoring - The Iowa SHPO may monitor activities carried out pursuant to this Programmatic Agreement. The Advisory Council may review such activities if so requested.

5. Amendments - Any party to this agreement may amend this agreement upon written request; whereupon, the parties will consult to consider the amendment.

Engineering Strategies
for Management of
Historic Segments of the Lincoln Highway
within the State of Iowa

1. Introduction
The FHWA, Iowa DOT and SHPO recognize that the Lincoln Highway corridor is part of our historic heritage. Much of the route has been modified through the development of modern safe transportation facilities and no longer qualifies for inclusion in the National Register of Historic Places. However, there are a number of segments of the Lincoln Highway route that retain significant integrity to qualify for the National Register of Historic Places. This strategic plan proposes recommendations for maintaining and/or rehabilitating those segments that are historically significant while balancing the need to retain the features that qualify the route for the National Register.

2. Authority
Section 106 of the National Historic Preservation Act requires states to take into account the effects of federally funded or permitted undertakings upon historic properties and allow the Advisory Council on Historic Protection an opportunity to comment. According to Iowa Code 314.24 cities, counties and the Department of Transportation shall to the extent practicable preserve and protect the historic heritage of the state in the design, construction, maintenance and repair of the roads, streets and highways. Damage and destruction shall be avoided and state agencies shall use reasonable alternatives if available at no significantly greater cost.

According to the Iowa Code 303.2, state agencies that own, manage or administer historic properties must enter into a 28E agreement with the Department of Cultural Affairs to insure proper management, maintenance and development of the historic properties.

3. Goal
This strategic plan is designed to establish appropriate management practices to maintain and rehabilitate segments of the Lincoln Highway that has been determined to retain sufficient integrity to qualify for inclusion on the National Register of Historic Places.

4. Types of resources to be managed
The Lincoln Highway has been evaluated from many perspectives including the original road design geometrics - the traveled road way width, shoulder width, ditch width and depth, and right of way; road way features - bridges, culverts, road markers, fences and signs; landscape and land use; and transportation related buildings - gas stations, garages, cafes, hotel/motels and cabin courts. Historic districts and landscapes of which the Lincoln Highway may be an element should also be considered.

The significant routes may be paved, gravel, dirt or abandoned roads. The paved roadways have been divided into categories of rural local or rural collector. The rural collectors have been functionally categorized according to average daily traffic (ADT); less than 400 ADT, greater than 400 and less than 2000 ADT and greater than 2000 ADT.

Private parties may own historically significant structures related to the Lincoln Highway. This strategic plan will not apply to such properties unless a federally funded project would affect them.

5. Activities that will not adversely impact historic resources
It is essential for public transportation facilities to be properly maintained for the safety of the motoring public. On non-paved segments of the Lincoln Highway, most contemporary maintenance activities that retain the original roadway geometrics features should not adversely affect the historic nature of the route. Examples of these features include road and shoulder width, cross-slope or roadway crown, and ditch cross section. Applying additional granular material, cleaning ditches, mowing and brush/tree removal should not adversely affect the historic nature of the Lincoln Highway. It is recommended that local/regional quarries be used to obtain the appropriate type of granular material, in order to match existing granular surfacing on roadways where additional material is needed. [See exhibit 1]

6. Activities that are considered an adverse effect
The engineering technology of early twentieth-century roadway is a common thread that links Lincoln Highway resources across the state. Changing design features of that early technology such as the travel width, shoulder width, increasing the right of way beyond 100 ft, replacing original bridges and culverts could be considered adverse affects. Retaining the drivability of the current Lincoln Highway route is a priority. Retain, as much as practical, the alignment that illustrates many elements of the early 20th century driving experience - the engineering and construction techniques, following a Jeffersonian grid and cultural landscapes or landforms, and riparian system. The retention of the horizontal and vertical alignment reveals these relationships to the traveler. If realignment or abandonment is necessary, strive to retain the original features for interpretive value.

When safety issues dictate the need to reconstruct an historic road, context sensitive design practices must be considered. For example, resurfacing PCC pavement with asphalt could constitute an adverse effect, while a preferable context sensitive design could be to overlay the roadway with bonded or un-bonded concrete and white-topping or ultra-thin white-topping.

Other types of context sensitive strategies to consider:

Bridges and culverts that retain unique design and symbolism associated with the Lincoln Highway, and those designed by Conde B. McCullough contribute to the historic integrity of the Lincoln Highway. Before considering replacement explore options such as:

If avoidance strategies are not feasible, consider minimization through recommended context sensitive rehabilitation strategies. Consider the use of new bridge engineering technologies using state-of-the-art materials such as:

Managing the resources within the right of way through context sensitive designs that mitigate impacts of improvements solidify the linking thread as a significant, unique resource for the state. Cutting edge engineering strategies that built the first transcontinental highway became the modern equivalent of applying state-of-the-art engineering technologies to improve the roadway while retaining the characteristics that most exemplify the tradition of the Lincoln Highway.

7. How to proceed if adverse impacts cannot be avoid
If minimization or avoidance is not feasible and a historic property must be replaced, follow the Section 106 guidelines (36CFR800.6) of consulting with SHPO, FHWA,DOT and interested parties to resolve the adverse effect through the determination of appropriate mitigation measures for the specific historic property. Mitigation measures could include documentation of the historic and engineering technologies of the existing structure and the new technologies utilized in the new facility, context sensitive enhancements for the new facility, or measures that heighten public awareness of the Lincoln Highway.
