The Virginia Department of Transportation (VDOT) and Prince William County(PWC) just completed the widening of Route 1, between Mount Pleasant Drive and Annapolis Way just south of the Occoquan River in late 2020.
A massively over-designed interchange at Routes 1 and 123 was also included as part of the project to provide better network connectivity between the Belmont Bay community and Interstate 95. But, due to the high cost of the interchange, only the Right of Way (ROW) was obtained and the construction was shifted to a future Phase 2.
