I-35 Texas Pile-Up Crash Reconstruction
This case involved a catastrophic multi-vehicle pile-up on a Texas toll road during icy winter conditions. Over 100 vehicles collided due to black ice, poor visibility, and the toll road operator’s failure to apply de-icing measures despite multiple weather warnings. The incident caused numerous injuries and fatalities, sparking legal action around liability and road maintenance negligence.

Case Overview
Challenge
Challenge:
-Over 100 impacted vehicles created a complex reconstruction environment.
-Icy conditions and weather warnings raised questions about proper road treatment.
-Needed to visually prove road conditions, driver visibility, and the timeline of events.
-Technical precision was essential to support expert and legal arguments.
Visual Strategy
Visual Strategy: Iconographics collaborated closely with attorneys and forensic experts to create a visual narrative that was scientifically accurate and emotionally impactful.
Compared software tools (Pix4D, Agisoft) for optimal photogrammetry results.
Chose Bentley iTwin for architectural-grade fidelity and texture realism.
Balanced visual immersion with technical accuracy to align with expert testimony.
Our Work
Our Work: Cinematic Flyover Reconstruction
Built using high-resolution drone footage and photogrammetry.
Included road textures, volumetric lighting, snow, fog, and smoke effects for immersion.
Follow-Cam Simulation of Prime Inc. Truck
Visualized the trajectory of the defendant’s semi-truck.
Demonstrated limited visibility and short reaction time approaching the crash site.
Medical Visualization & Injury Breakdown
Partnered with medical experts to animate the client’s position and injuries inside the vehicle.
Used realistic motion and anatomy (avoiding “T-pose” figures) for emotional and factual impact.
Supplementary Visual Evidence
Integrated dashcam footage and documented weather alerts.
Supported claims of driver error and inadequate de-icing by the toll road operator.
Results
Results: Delivered a suite of visuals that elevated mediation and trial preparation. Attorneys used visual aids to support expert opinions and causation arguments. Set a new standard in 3D crash scene reconstructions with cinematic clarity and forensic accuracy.
