In mid-1926, a separate piece of VA 392 was assigned to what had been put into the system as VA 351 from Dendron through Wakefield to its SCL (current SR 628-620 jct). This piece was not connected to any other part of the highway system.
In 1925 (per Wikipedia), the ferry from Jamestown to Scotland was established as a private enterprise. The Jamestown wharf was on Jamestown Island at that time.
About 1927, VA 392 was rerouted to use today's VA 5 and 31 directly to SR 682.
In March 1927 (CTB), VA 392 was extended from Dendron to VA 10 Surry C.H.
In March 1928 (CTB), a permit was granted to Eastern Virginia Bridge Company to build a toll bridge between Scotland Wharf and Jamestown Island.
In Aug 1928, both pieces of VA 392 were renumbered as VA 510. Today the southern piece is VA 31 and a liitle SR 628.

There were TO VA 392 shields in both directions on nearby US 58-221 back to at least 1993. The access road itself was posted from SR 707.
