This section from a 1915 South Dakota map shows Cedar Pass Scenic Highway that went from the Oacoma area to Interior. In the 1920s and before, many roads in the United States received names. They were often associated with a booster group which collected dues and published trail guides and newsletters. Please contact us if you have information about the Cedar Pass Scenic Highway or its booster association.
The South Dakota map was published by the Geographical Publishing Company of Chicago, Illinois in 1915. After the 1920’s, the United States and many of the states developed a numbering system for roads. This route was slightly altered to became US Highway 16, and later, altered again to become Interstate 90.
This map will become part of the Chilson Collection.
