A potential project evaluated recently during the Hampton Roads Regional Connectors Study, which is now currently focused on the Third Crossing, I-664, and VA-164 Widening, would have extended the Third Crossing from I-664 to US-17, a new alignment parallel to US-258 to north of Smithfield along VA-10, and a new bridge over the James River tying back into I-64 somewhere near Williamsburg. This project, however, was dropped from further evaluation.
Perhaps, and this may be getting into more fictional territory, but extend VA-164 or the Third Crossing west of US-17 along the VA-10 corridor to meet I-295 south of Hopewell. This would provide a similar corridor what the now-defunct US-460 freeway proposal would have provided, and a viable alternative between Richmond-Petersburg and the Southside that avoids the Peninsula.
