State Route 124 connected SR 30 in Port Richmond (now within West Point limits) to the former Port Richmond Airport along present SR 701 (Euclid Boulevard).

[citation needed] SR 124 was downgraded to secondary in 1943 after the airport was abandoned.

[4] State Route 199 followed current secondary SR 684 from US 360 at Millers Tavern east across US 17 at Center Cross to the Rappahannock River at Bowlers Wharf.

9.6 miles (15.4 km), from Millers Tavern almost to Center Cross, was added to the state highway system in 1928 as State Route 604,[5] which was extended the rest of the way to Bowlers Wharf in 1930.

[14] The east end from Snell to Post Oak would return to the primary system in 1950 as part of SR 208, which took a more direct route from Post Oak southwesterly towards US 522.

A majority of the route from the Wilderness Corner end was added to the state highway system in 1928 as State Route 617,[21] which was extended the remaining 2.4 miles (3.9 km) to Spotsylvania in 1930.

[citation needed] State Route 213 followed current secondary SR 610 from the historic Aquia Church northwest across US 1 at Aquia Tavern to the Stafford-Fauquier County line east of Somerville.

[34] State Route 217 extended southwest from US 17 at Ark to 2 miles (3.2 km) short of Allmonds Wharf on the York River along present secondary SR 606.

[13] State Route 293 ran along present secondary SR 633 from SR 30 at Whites Shop (just southeast of King William) south to a point approximately 1⁄4 mile (0.40 km) south of Lanesville.

Never making it to Lester Manor on the Pamunkey River (as the descriptions from the 1930 and 1932 additions imply was the aim), SR 293 was downgraded to secondary in 1944[61] as an extension of existing SR 633.
