Historic Transportation Marker Grant Program

Sample of the Historic Transportation marker design.

The following subjects qualify for Historic Transportation marker grants:

Often considered a precursor to interstate highways, transportation canals helped facilitate the movement of goods and people. This spurred development of towns and villages along the way, leading to an overall expansion of the nation.

Bridges and tunnels allowed people to overcome natural obstacles such as rivers and mountains, expediting travel. If a bridge has been rebuilt or restored after 1945, components of the original structure must still be extant.

Existing railroad structures such as depots, stations, rail cars and engines will be considered. Trolleys and interurbans are included in this category. Applications for former railbeds that lack an existing structure will not be accepted for this marker program.

Existing airfields, hangers, planes and other aircraft will be considered. Use for transportation of goods or people must be proven.


Historic Transportation grants are available to 501(c)(3) organizations, nonprofit academic institutions, and local, state and federal government entities within the United States. Interested individuals are encouraged to contact an eligible local organization, such as a municipal historian or historical organization. They will often apply for the grant on behalf of the individual.

Historic Transportation markers must recognize a historical fact that occurred by 1945. After World War II, the United States saw a significant change in transportation with the increase in automobile ownership and the construction of the interstate highway system. We seek to commemorate the way in which goods and people were transported prior to these transformative events.

  • Marker inscription must be proven with primary source documentation.
  • Subject must be historically significant to the larger community or beyond.
  • Inscriptions must be clear about why the subject is historically significant.
  • Inscriptions should maximize available character limits.
  • Key dates must be included for framing context.
  • Markers must be installed near an existing site or structure.
  • Structures must be publicly accessible for viewing.

Marker Design and Text Guidelines 

The colors of the markers are blue with white lettering and a black border. Markers are 18” x 32” cast aluminum with a 7’ aluminum pole. 

The title line allows 15 characters and the five body lines can have 27 characters each, including spaces and punctuation. There is a required credit line at the bottom of the marker which is always included.  

Please review our marker inscription style guide as you prepare your application:  Marker Style Guide

Historical Accuracy 

Primary source documentation is required to verify historical accuracy. The applying agency is responsible for supplying photocopies, scans or photos of the sources and specific statements used to verify historical facts. If selected, the strength of the supporting materials substantially lessens the time between acceptance and funding. If the Pomeroy Foundation cannot substantiate the historical accuracy of the proposed marker text based on the supporting documentation provided, the opportunity for approval is limited.

  • proposed inscription for marker

Additional required documents are:

Grants for the Historic Transportation program cover the entire cost of a marker, pole, and shipping. There is no cost to you. If your application is approved, upon receipt of your signed Acceptance Letter, the William G. Pomeroy Foundation will mail a check for the total amount made payable to the applying agency. Instructions for ordering your marker will accompany the check. The grant recipient is responsible for installation of the marker.

Marker Placement

Please carefully consider the location where the marker is to be installed.

  • Markers should not be placed on high-traffic roadways or roadways where vehicles are traveling at a high rate of speed if there is no place for a vehicle to safely pull over out of traffic.
  • Markers should not be placed where the visitor must intrude on private property to read it.

Before installing your marker, please be sure you are following all of your state’s guidelines around digging and excavation.
