Key Takeaways
The I-526 Lowcountry Corridor project is widening I-526 from 4 to 6 lanes across 7 miles in North Charleston and West Ashley, with a budget estimated at $1.5 billion (total program approaching $7 billion). In November 2025, a pickup truck struck two construction workers in the I-526 East work zone at the Westmoreland Bridge — Kaleb Tilley, 23, was killed. In February 2026, a tractor-trailer with a high load struck an I-526 sign and then hit the Eagle Drive overpass on I-26. South Carolina gives injury victims 3 years to file a lawsuit (S.C. Code § 15-3-530) and allows recovery if less than 51% at fault. Claims against SCDOT require compliance with the SC Tort Claims Act. Contact Roden Law's Charleston office at (843) 790-8999.
The I-526 Lowcountry Corridor Project: Up to $7 Billion in Construction
The I-526 Lowcountry Corridor project is widening I-526 from four to six lanes across approximately 7 miles from Rivers Avenue to Paul Cantrell Boulevard in North Charleston and West Ashley. With an estimated budget of $1.5 billion — and some reports citing the total program cost approaching $7 billion — this is one of the largest highway construction projects in South Carolina history. The corridor serves as the primary beltway around Charleston, carrying commuters, port freight, and commercial trucks through a ring that connects I-26, the Port of Charleston, Charleston International Airport, and the region’s major employment centers.
For the duration of construction, drivers and truckers must navigate narrowed lanes, active lane shifts, temporary barriers, bridge work, and constantly changing traffic patterns on a highway that already operates at or above capacity during peak hours. The combination of heavy truck traffic, active construction, and high speeds creates conditions where crashes are more frequent and more severe.
Recent Fatal and Serious Crashes in the I-526 Construction Zone
November 2025: Construction Worker Killed at Westmoreland Bridge
In November 2025, a pickup truck struck two construction workers in the I-526 East work zone at the Westmoreland Bridge. Kaleb Tilley, 23, of Mount Airy, North Carolina, was killed. He was transported to MUSC where he died from his injuries. I-526 East was blocked until 1:45 a.m. while investigators processed the scene. This crash underscores a critical and often overlooked dimension of construction zone safety: the workers building these projects face daily exposure to high-speed traffic separated from them by nothing more than cones and temporary barriers.
February 2026: Tractor-Trailer Strikes Overpass on I-526 to I-26
In February 2026, a tractor-trailer carrying a “high load” struck a sign on I-526 westbound before Rivers Avenue, then continued onto I-26 and struck the Eagle Drive overpass. Construction zones frequently alter overhead clearances, ramp heights, and sign placements. Truck drivers relying on pre-construction clearance data or outdated GPS may not realize that temporary structures, lowered signs, or reconfigured ramps have reduced the available overhead space. An overheight strike on a bridge or overpass can cause catastrophic structural damage and endanger every vehicle on and under the structure.
March 2025: Deadly Hit-and-Run on I-526 East
In March 2025, a deadly hit-and-run occurred on I-526 eastbound in the construction corridor. Hit-and-run crashes are especially dangerous in construction zones because narrowed lanes and concrete barriers can trap disabled vehicles in the travel lane with no shoulder to escape to. Victims may be struck by secondary traffic before emergency responders can reach them through the construction zone congestion.
Why the I-526 Construction Zone Is Dangerous for Trucks and Workers
Drivers and Construction Crews Share the Same Space
Unlike a rural highway widening where construction occurs far from travel lanes, the I-526 project requires workers to operate immediately adjacent to live traffic. Bridge work, barrier placement, and lane restriping all occur within feet of vehicles traveling at highway speeds. The November 2025 fatality at Westmoreland Bridge demonstrates the lethal consequences when a vehicle enters the work zone. Construction workers have no protection beyond temporary barriers and high-visibility vests against an 80,000-pound truck.
Altered Clearances and Overhead Hazards
The I-526 project involves significant bridge and overpass work, which can temporarily change overhead clearances. The February 2026 overheight strike — where a truck hit a sign on I-526 and then struck the Eagle Drive overpass on I-26 — illustrates the cascading danger. Truck drivers must verify current clearance heights, but construction zones may not update all signage in real time as work progresses. A single overheight strike can close an overpass for emergency structural inspection, disrupting traffic across the entire corridor.
No Shoulders, No Escape
The widening project places concrete jersey barriers on both sides of the travel lanes, eliminating shoulders and emergency pulloff areas. When a crash occurs — whether a rear-end collision in congested traffic or a tire blowout — disabled vehicles remain in the travel lane. This creates a chain-reaction hazard, particularly for trucks that cannot stop quickly. The lack of shoulders also delays emergency response, as ambulances and fire trucks must navigate through the same narrow lanes as regular traffic.
Liable Parties in I-526 Construction Zone Crashes
| Potentially Liable Party | Basis for Liability |
|---|---|
| Truck driver | Speeding in work zone, distracted driving, failure to verify overhead clearances, failure to obey construction zone speed limits |
| Trucking company | HOS violations, inadequate training on construction zone navigation, failure to update route planning for active construction |
| SCDOT / project owner | Inadequate signage, improper traffic control design, failure to update clearance warnings (claims subject to the SC Tort Claims Act, S.C. Code § 15-78-80) |
| Construction contractor | Improperly placed barriers, equipment in travel lanes, inadequate work zone lighting, failure to follow MUTCD standards |
| Subcontractors / traffic control vendors | Failure to maintain safe lane closures, missing or incorrect signage, improperly placed cones and barriers |
What to Do After a Crash in the I-526 Construction Zone
- Call 911 immediately — South Carolina Highway Patrol and North Charleston Police respond to I-526 crashes. If you are in the construction zone with no shoulder, stay in your vehicle with your seatbelt on and hazard lights activated.
- Document the work zone: Photograph construction signage, speed limit signs, barrier placement, lane markings, and any construction equipment near the crash. Conditions in the corridor change weekly.
- Record the truck: Company name, USDOT number, trailer number, cargo type, and any overheight or overweight markings.
- Get medical treatment: MUSC is Charleston’s Level 1 trauma center and the closest major hospital to the I-526 corridor. Get evaluated even if you feel fine — construction zone crashes frequently involve high-speed impacts with delayed-onset injuries.
- Contact a truck accident attorney within 24–48 hours — ELD data, dash cam footage, work zone traffic control plans, and SCDOT project records must be preserved before they are altered or overwritten.
South Carolina Law: Deadlines & Fault Rules
- Statute of limitations: 3 years from the date of injury (S.C. Code § 15-3-530)
- Comparative fault: South Carolina allows recovery if you are less than 51% at fault. Your compensation is reduced by your percentage of fault.
- SC Tort Claims Act: Claims against SCDOT or government entities are subject to the SC Tort Claims Act (S.C. Code § 15-78-80), which imposes caps and procedural requirements. Filing deadlines for government claims may be shorter than the standard statute of limitations.
