In March 1933 (CTB), a permit was granted to Eastern Virginia Bridge Company to build a bridge between Scotland Wharf and Jamestown Island.
In July 1933, VA 510 became part of VA 31. From Jamestown to Williamsburg it is VA 5, VA 31, SR 682, west along today's Colonial Pkwy, then cut south at the parking area to a causeway (still visible on Google Earth) and crossed Thoroughfare Creek onto Jamestown Island to meet the ferry in the area of the historic settlement.

VA 510 #2: According to the 2001 and 2003 VDOT route logs, a proposed VA 510 will be built from I-564 to the US Naval Base and International Terminal.
In 2012, the project now known as the I-564 Intermodal Connector received the go-ahead. This road would run from I-564 near Chambers Field over to a new interchange near Hampton Blvd, connecting to N.I.T. and the southern part of Naval Station Norfolk. It lines up with the planned Patriots Crossing ("the thrid crossing") over to I-664 just south of the south tunnel entrance at MMBT.
The link above implies the connector might be part of I-564. No current document associated with the project retains the VA 510 designation.
The Intermodal Connector opened in 2018 with no primary route number designated initially. As of 2025 it is internally designated as I-564 EXT.
