The Potomac Company was created in 1785 to make improvements to the Potomac River and improve its navigability for commerce. The project is perhaps the first conceptual seed planted in the minds of the new American capitalists in what became a flurry of transportation infrastructure projects, most privately funded, that drove wagon road turnpikes, navigations, and canals, and then as the technology developed, investment funds for railroads across the rough country of the Appalachian Mountains.

The Mount Vernon Conference was a meeting of delegates from Virginia and Maryland held March 21–28, 1785, to discuss navigational rights in the states' common waterways. On March 28, 1785, the group drew up a thirteen-point proposal to govern the rights of both states on the Potomac River, Pocomoke River, and Chesapeake Bay. Known as the Mount Vernon Compact and formally titled as the Compact of 1785, this agreement not only covered tidewater navigation but also extended to issues such as toll duties, commerce regulations, fishing rights, and debt collection. Ratified by the legislature of both states, the compact helped set a precedent for later meetings between states for discussions into areas of mutual concern.
