The canal that was to become later known as the 17th Street Canal seems to have had its origin at the start of the 1850s as a canal dug through swampy ground to raise a parallel right of way where the Jefferson and Lake Pontchartrain Railway was built. The railway, in business from 1853 through 1864, connected the town of Carrollton, Louisiana (along the Mississippi River front) with a shipping port on Lake Pontchartrain at what became Bucktown, Louisiana, a distance of about . At the time, most of the land between the two terminals was undeveloped swamp.
