Madison also approved federal spending on the Cumberland Road, which provided a link to the country's western lands. Congress planned for the road to extend from Baltimore to St. Louis, which would help provide for the settlement of lands formerly occupied by Tecumseh's Confederacy. In his last act before leaving office, Madison vetoed the Bonus Bill of 1817, which would have financed more internal improvements, including roads, bridges, and canals. In making the veto, Madison argued that the General Welfare Clause did not broadly authorize federal spending on internal improvements.
