History of state highways in Virginia

The History of State Highways in Virginia begins with Virginia's State Highway Commission, which was formed by the General Assembly in 1906. In 1918 the General Assembly designated a 4002-mile (6441 km) state highway system to be maintained by the Commission. Beginning in 1922, the Commission was authorized to add annually mileage equal to 2.5% of the original system (100 miles or 161 km). These highways were numbered from 1 into the 20s; by 1922 suffixed spurs had been added (such as 7X from 7). In 1923, the first renumbering was implemented, in which State Routes 1 to 9 became 31 to 39. The spurs were renamed to use numbers rather than letters (such as 114 from 11), and four-digit numbers were used for spurs of spurs (such as 1141 from 114) or for "rollovers" (such as 1010 from 10, as 10
