As settlers moved into the old Northwest Territory after 1800, transportation routes became an important priority. Indiana’s brief experience with canal building began with the passage of the Indiana Mammoth Internal Improvement Act of 1836. Whitewater Canal was one of several projects funded by this act. The Whitewater Canal started in Lawrenceburg and originally ended at Cambridge City, on the Old National Road. Hagerstown merchants financed an extension to their town, making the canal 76 miles in length.
