After the Revolution, various infrastructure projects began to be developed, including the Dismal Swamp Canal, the James River and Kanawha Canal, and various turnpikes. Virginia was home to the first of all Federal infrastructure projects under the new Constitution, the Cape Henry Light of 1792, located at the mouth of the Chesapeake Bay. Following the War of 1812, several Federal national defense projects were undertaken in Virginia. Drydock Number One was constructed in Portsmouth in the 1827. Across the James River, Fort Monroe was built to defend Hampton Roads, completed in 1834.
