The $120 million federally funded Interstate 95 / Route 630 Interchange Relocation and Route 630 Widening project constructed a new diverging diamond interchange at Exit 140 in Stafford County, Virginia. This project addressed growing regional transportation needs by improving traffic flow and safety. Key components included building two bridge overpasses, widening Route 630 to four lanes west of I-95, and implementing signalized intersection upgrades at Ramoth Church Road and Winding Creek Road.
The project also extended Hospital Boulevard to connect with Route 1 at Stafford Hospital and constructed two new commuter parking lots to support regional transit. Completed on time and under budget, the project met all milestones and earned the design-builder completion incentives, exemplifying efficient and effective infrastructure delivery.

Comprehensive Management and Inspection Solutions
ATCS supported VDOT with managerial, technical, and administrative professionals, providing expertise in project management, environmental compliance, construction management, inspections, project controls, ITS, stakeholder facilitation, public outreach, communications, safety inspections, and survey and mapping services. Our Responsible Charge Engineer oversaw daily operations, offering decisive leadership, supervising staff, and overcoming complex challenges to ensure steady progress.
To adapt to project demands, ATCS’ Construction Inspection Coordinator worked closely with VDOT’s construction management team to reassign or add staff as needed, maintaining an efficient and lean workforce. Our Senior Scheduling Specialist was instrumental in establishing the project’s baseline schedule and conducting monthly updates, ensuring adherence to timelines and mitigating risks.
Beyond schedule management, ATCS handled Right-of-Way management, oversaw the plan review process, and addressed stakeholder needs by coordinating with local organizations and citizens. This coordination included sharing project updates, work schedules, and traffic maintenance strategies to enhance public awareness.
Over the 2.5-year project, ATCS provided consistent engagement, ensuring environmental compliance and supporting seamless project progression toward successful completion.

Drone Technology Enhancing Infrastructure Delivery
ATCS’ Unmanned Aerial Systems (UAS) played a crucial role in several project aspects, providing a cost-effective, efficient, and safe means of data collection and monitoring:
- Public Outreach and Visualization: Drone photography gave the community a bird’s-eye view of the new interchange, helping residents visualize its function and prepare to navigate the redesigned alignment.
- Inspections and Compliance: Aerial video and photography facilitated inspections of erosion control measures and water quality compliance across active work zones, streamlining environmental oversight.
- Milestone Monitoring: Regular drone-captured imagery documented monthly progress, allowing the team to track schedule adherence and identify areas requiring mitigation.
- Project Evolution: Comprehensive drone documentation captured the project’s progression from inception to completion, delivering valuable insights into work performance and contract compliance.
- Close-Out Documentation: Aerial imagery provided concrete evidence of as-built conditions, expediting the C-5 process and ensuring efficient project closeout.
Community and Regional Impact
This project significantly enhances mobility and safety for Stafford County residents while addressing the region’s growing transportation demands. The new diverging diamond interchange improves traffic flow and reduces congestion, while widened roadways and upgraded intersections create a more efficient transportation network. By supporting regional transit with commuter parking lots and connecting key destinations like Stafford Hospital, the project contributes to a more connected, resilient, and sustainable community.
