I-95 Bidirectional Lanes – June 2024 – Springfield to Dumfries, Virginia

Selected by HDR Engineering, we provided geotechnical drilling services for the Virginia Department of Transportation’s (VDOT) I-95 Bidirectional Lanes project. This major infrastructure initiative addresses congestion on one of the busiest sections of Interstate 95 between Springfield and Dumfries, Virginia.
The project involves widening the highway and implementing multi-use improvements, including a movable barrier system that allows dynamic lane allocation during peak hours.
Our scope included over 500 test borings ranging from 10 to 125 feet in depth. The investigation featured rock and pavement coring, undisturbed sampling, and groundwater monitoring well installations. All work took place under active highway conditions, requiring careful planning and execution of limited-access and night-shift operations.
This effort involved collaboration across multiple geotechnical divisions and demanded flexible scheduling to overcome early permitting and access delays. Successfully completing this phase demonstrated our ability to manage large-scale infrastructure investigations within active transportation corridors and challenging site conditions.
