The transportation vehicles of the 1860’s did not require the wide, straight highways of the present. However, several good roads came into the city from the east, south, and west where they joined with the Richmond Turnpike. Along these roads passed supply wagons, couriers, and, on occasion, troops on their way to repel the foe. Several were built of logs laid across the road to form a hard surface. Because of this they were called “plank roads.” Two of the most important arteries of traffic into Petersburg were the Jerusalem Plank Road, connecting Petersburg with Jerusalem (now Courtland), Va., and the Boydton Plank Road which led south through Dinwiddie Court House. Among others of importance were the City Point, Prince George Court House, Baxter, Halifax, Jordon Point, Squirrel Level, and Cox Roads.

The shaded area is the approximate line of Union control in early 1864. The three arrows indicate the major drives planned by the Union army for 1864. (Railroads serving Rich. and Petersburg are in heavy lines.)] It was the railroads more than the highways, however, which gave to Petersburg a significance out of all proportion to its size. Tracks radiated from the city in all directions. The Richmond and Petersburg Railroad left the city to the north; the Southside Railroad ran west to Lynchburg; the Petersburg and Weldon Railroad led south to North Carolina; the Norfolk and Petersburg Railroad passed through a ravine east of the city before turning southeast toward Norfolk; and the Petersburg and City Point Railroad struck out for the hamlet of City Point, situated at the junction of the James and Appomattox Rivers about 8 miles away. Because of its proximity, Petersburg became a part of the transportation system of the Confederate capital, serving as a major point of transfer to the larger metropolis for products and materials from the vast regions to the south and southwest. By June 1864, all but one railroad from the south and west into Richmond—the Richmond and Danville Railroad—passed through Petersburg. As other lines of supply were cut off or threatened, the dependence of Richmond upon Petersburg increased and made the security of that city a matter of vital concern.
