Cumberland County has a total area of 298.5 square miles. No interstate highway passes through the county. There are two main roadways—U.S. Route 60 and U.S. Route 45. Route 60, which accounts for 15 miles of roadway, connects Cumberland County to Buckingham on the western boundary and to Powhatan on the east. Route 45 connects Cumberland to Farmville/Prince Edward on the southern border and to Goochland on the northern border.
Route 60 has several miles of 5-line road, with a center turning lane, located west of Cumberland Courthouse. This section of road comprises the only divided highway in the county. Many secondary roads remain unpaved gravel roads. Moreover, the county has no stoplights, although one traffic light exists at the southern end of the county leading into Farmville.
