Jackson's Military Road was a 19th-century route connecting Nashville, Tennessee, with New Orleans, Louisiana. After the War of 1812, it was improved with federally-appropriated funds. The road was named for Andrew Jackson, hero of that war's Battle of New Orleans.
The appropriation for Jackson's Military Road was made on April 24, 1816:
Be it enacted by the Senate and House of Representatives of the United States of America, in Congress assembled, That the sum of ten thousand dollars be and are hereby appropriated, and payable out of any moneys in the treasury not otherwise appropriated for the purpose of repairing and keeping in repair the road between Columbia, on Duck River in the state of Tennessee, and Madisonville, in the state of Louisiana, by the Choctaw Agency, and also the road between Fort Hawkins, in the state of Georgia, and Fort Stoddard, under the direction of the Secretary of War.
On September 24, 1816, William H. Crawford, Secretary of War, informed General Andrew Jackson, who was then commanding the Army district at Nashville, of the appropriation, and directing that $5,000 be spent on the road to Louisiana. He noted that "I have received no information of the length of this road, the nature of the country through which it passes, or its present state. If there are many bridges to be erected the appropriation will be inadequate to the object. In that event the employment of a part of the troops may become necessary."
Jackson was officially in charge of the entire construction, including the First and Eighth Infantry and the artillery detachment who supplied the labor. However, much of the construction was supervised by his subordinates. Captain H. Young surveyed the route, completing this task by June 1817. Bridges were indeed needed, and an additional $5,000 was appropriated in March 1818. Major Perrin Willis took command of the construction gang, then numbering about fifty, in April 1819, when the road reached the Pearl River. The road was completed in May 1820, after 75,801 man-days of labor.
