A cultural resources study of historic roadside development properties was conducted in 1996-1998 by Gemini Research for the Minnesota Department of Transportation (Mn/DOT). The study's goal was to inventory all roadside development properties on current Mn/DOT right-of-way that contain pre-1961 standing structures and to evaluate the National Register eligibility of the sites. A total of 102 properties were inventoried. Eleven of the properties are listed on the National Register or located within a National Register historic district. The study recommends that 51 individual properties and 1 historic district containing 7 properties meet the registration requirements of the historic context entitled "Roadside Development on Minnesota Trunk Highways, 1920-1960" and are therefore eligible for the National Register under this context. A set of 102 inventory files and this final report are included among the study's final products.
Note: Some corrections/changes have been made in this supplement (November 1, 2006; August 26, 2008).
In 2002-2004 the Minnesota Department of Transportation (Mn/DOT), working through its consultant Gemini Research, conducted a cultural resources survey and evaluation of eight properties to be added to Mn/DOT's Historic Roadside Development Structures Inventory. The addition of the eight brings the total inventory to 110 properties. Gemini Research recommends that three of the eight newly-inventoried properties are eligible for the National Register of Historic Places. This document, intended as a supplement to the 1998 inventory report Historic Roadside Development Structures on Minnesota Trunk Highways, adds the eight new properties to the inventory, updates key inventory information, and corrects selected errors in the original inventory. The updated information lists, for example, the historic preservation treatment reports that Mn/DOT has prepared for National Register-eligible and -listed sites. The report also briefly discusses serious threats facing the inventory sites including their deteriorating physical condition.
