Revolution, coal produced in the Midlothian coal pits supplied the cannon factory on the James River at Westham, upstream from Richmond; it produced shot and shells for the Continental Army. By the end of the War, developers shipped Chesterfield coal to Philadelphia, New York, Boston and to every city in Virginia. Commenting on the area's coal in his Notes on the State of Virginia (1781–82), then-Governor Thomas Jefferson stated: "The country on James river, from 15 to 20 miles above Richmond, and for several miles northward and southward, is replete with mineral coal of a very excellent quality." During his presidency, Jefferson ordered coal from the Black Heath Mine in Midlothian for use in the White House. In 1989 the Chesterfield County Board of Supervisors approved a special area plan for Midlothian Mines Park, partly as a response to economic growth along Midlothian Turnpike resulting in population explosion. The core of the new "Special Area Plan" was based on the boundary of the plan of 1989 and extended westward to Route 288 as a natural boundary, and a map of the Midlothian community special area plan boundary was provided by John G. Ownby for the Richmond Times-Dispatch. Midlothian Mines Park, on the site of the first commercially-mined coal deposits in the Colony of Virginia, first opened for visitors in 2004. Early roads, first turnpike, and railroads In 1802, a petition to form the Manchester Turnpike Company was created by mine owners and investors. They wanted the construction of a macadam toll road at least 30 feet wide from Manchester to Falling Creek bridge. The toll road, Manchester and Falling Creek Turnpike, was built in 1804 to ease traffic on what is now Old Buckingham Road. Farm and passenger wagons were allowed to only pay the toll one-way, however coal wagons were to pay half toll on return due to the wear the heavy wagons would create on the road. It was graveled in 1807, making it Virginia's first hard-surfaced road. The road's descendant is known today as Midlothian Turnpike. By 1824, an estimated 70 to 100 wagons, each of which was loaded with four or five tons of coal, made a daily trip on the turnpike, transporting to the docks near Manchester the million or more bushels (30,000 metric tons) of coal that were produced in Chesterfield County each year. The heavily loaded coal wagons tended to cut deep ruts
