$60M Settlement in I-55 Work Zone Paraplegia Case

Multiple construction, engineering, and traffic control companies have agreed to pay $60 million to resolve claims that negligent highway work on Interstate 55 in Illinois contributed to a chain-reaction crash that left Sarah Grasser permanently paraplegic. According to court filings and counsel’s public announcement, the settlement concludes the litigation just days before trial was set to begin in the Circuit Court of Cook County. The underlying lawsuit alleged that work performed in an active construction zone created an unreasonably dangerous roadway condition, including a deep pothole, and that deficient traffic-control measures failed to protect motorists from foreseeable hazards. The resolution underscores the high exposure that can arise when roadway maintenance, inspection, and traffic-control responsibilities intersect.

Allegations Centered on an Unsafe Construction Zone

The amended complaint alleged that defendants involved in the I-55 project created and/or allowed a hazardous condition to persist in a three-lane construction zone in Will County, Illinois. Plaintiff contended that a “major pothole” attributable to the work area prompted a vehicle in the adjacent lane to make an evasive maneuver that precipitated the crash. The defendants included entities described as contractors performing road construction, engineers inspecting the work, and traffic control companies charged with maintaining safe travel through the zone, with alleged failures spanning roadway surface conditions, work-zone monitoring, and warnings to drivers.

The incident occurred on Aug. 30, 2022, while Grasser was traveling northbound in the left lane, according to the pleadings and counsel’s account of events. Plaintiff asserted that an unknown white vehicle to her right swerved into her lane to avoid the pothole and struck her vehicle, causing her to lose control, leave the roadway, and overturn in a ditch. The claimed injuries included a T12 vertebra burst fracture, resulting in paralysis from the waist down. The case proceeded on theories that the hazardous condition and associated work-zone safety deficiencies were substantial contributing causes of the collision sequence and its catastrophic outcome.

Disputed “Phantom Vehicle” and Causation Issues Approaching Trial

As the matter headed toward trial, a central factual dispute concerned the existence and role of the unidentified white vehicle described in the pleadings. Plaintiff maintained that the vehicle collided with her car, while the defense position, as characterized by plaintiff’s counsel, was that no such vehicle was involved. The record also included at least one witness statement asserting there was no car that hit Grasser, though plaintiff’s counsel indicated that the witness’s position was not entirely consistent with earlier statements to police contemporaneous with the crash.

Causation analysis also appeared to incorporate alternative crash dynamics tied to the roadway condition itself. Plaintiff’s counsel indicated that the plaintiff’s expert evaluated the possibility that the white vehicle may have swerved into the lane without making contact, while still setting in motion the loss of control in the construction zone environment. That framing preserved a theory in which the alleged pothole and work-zone configuration remained pivotal even if physical contact could not be conclusively shown. With juror perception and competing reconstructions likely to dominate trial presentation, the parties resolved the dispute through a global settlement before opening statements.

Settlement Structure and Implications for Roadway Project Risk

The $60 million agreement was announced by the plaintiff’s counsel, and it apportions payment among multiple defendants rather than a single entity. According to counsel’s identification of settling parties, contributors include K-Five Construction Corp., D. Construction Inc., Gallagher Asphalt Corp., R.M. Chin & Associates Inc., Aecom Technical Services Inc., Atlas Engineering Group Ltd., Traffic Control & Protection Inc., TSI Traffic Control LLC, Maintenance Coatings Co., and Work Zone Safety Inc. The plaintiff is represented by Clifford Law Offices PC, according to the announcement and court filings.

The settlement amount reflects the significant lifetime costs associated with permanent paraplegia, including ongoing attendant care and durable medical equipment, as described by counsel. Although the case ended without a verdict, the resolution highlights how work-zone condition allegations can create multi-party exposure spanning contractors, inspectors, and traffic-control providers when the asserted mechanism involves roadway defects and driver behavior in constrained lanes. More broadly, the matter illustrates how factual uncertainty—such as the presence of a “phantom” vehicle—may be managed through settlement when parties weigh trial risk against the potential for large damages tied to catastrophic injury.
