Which South Carolina Interstates Are The Most Dangerous?

Dangerous Roads & Highways In SC

Like any state, South Carolina has its share of dangerous interstates. Especially in Mount Pleasant, Charleston and other more heavily populated areas, otherwise safe intersections become much more dangerous as traffic increases.

If you or a loved one has been in a serious auto accident, our team of experienced attorneys can help you. We have the knowledge and tenacity to make sure you get the compensation award you deserve for the injuries you have suffered.

South Carolina Interstates

Right in the heart of Charleston, Interstate 26 is one of the most dangerous roadways in the entire state. In fact, the intersection of Ashley Phosphate and I-26 just north of Charleston has nearly double the accidents of any other intersection in the entire Tri-County area. ^*

Interstate 95, which also runs through Charleston, I-85 and I-77 all have their share of serious accidents, as well.

I‑26 (Charleston — Columbia — Spartanburg corridor)

I‑26 connects Charleston with Columbia and the Upstate and is one of the state’s busiest east‑west interstates. Around Charleston and Mount Pleasant, heavy commuter traffic, freight movements and frequent construction produce sudden slowdowns, work‑zone collisions and multi‑vehicle pileups. In the Midlands and Upstate, high speeds and steep grades can increase rollover and severe truck‑involved wreck risk. Typical injuries on I‑26 range from whiplash to catastrophic spinal and brain injuries when large vehicles or high speeds are involved. Critical evidence often includes traffic‑camera and construction logs, dashcam footage, and, in truck cases, ELD/driver‑log and maintenance records. If you were hurt on I‑26, contact Drennan Law Firm at 843-352-4149 so time‑sensitive evidence can be preserved.

I‑95 (coastal / Pee Dee / Lowcountry corridor)

I‑95 is South Carolina’s major north‑south freight route and sees heavy long‑haul truck traffic, seasonal tourist surges, and varied weather that contribute to high‑speed rear‑ends, tractor‑trailer collisions and multi‑vehicle pileups—especially near rest areas and major interchanges around Florence and the Lowcountry. Injuries in I‑95 crashes are often severe, including TBIs, spinal injuries and fatalities when trucks are involved. Truck collisions add regulatory and evidentiary complexity (FMCSA rules, ELD data, driver logs), so prompt preservation of electronic records and carrier files is crucial. If a truck was involved in your crash on I‑95, call Drennan Law Firm at 843-352-4149 for immediate assistance preserving critical evidence.

I‑85 (Upstate corridor: Greenville — Spartanburg — Anderson)

I‑85 carries dense commuter and commercial traffic through the Upstate, with frequent interchanges, heavy merging and speed differentials that create risky weaving zones. Common collisions include unsafe lane changes, sideswipes, and chain‑reaction crashes near urban junctions. Victims may suffer broken bones, neck and back injuries, and more severe trauma in truck‑involved or high‑speed incidents. Investigations often rely on dashcam/traffic camera footage, skid‑mark analysis and, when commercial vehicles are involved, carrier maintenance records. Early legal involvement helps ensure evidence isn’t lost and that all potential defendants are identified. If you were injured on I‑85, contact Drennan Law Firm at 843-352-4149.

I‑77 (Charlotte area connector / Rock Hill — Columbia corridor)

I‑77 serves as a busy regional connector in the northern part of the state and through areas that see commuter bottlenecks and abrupt merges. Typical risks include rear‑end pileups in congestion, rollover crashes on higher‑speed stretches, and severe impacts when heavy vehicles are involved. Injuries often include spinal trauma, fractures and head injuries. Key investigative steps include preserving scene photos and camera footage, obtaining vehicle event data and analyzing roadway geometry or signage at problematic interchanges. If you or a loved one were hurt on I‑77, call Drennan Law Firm at 843-352-4149 for a free case review.

I‑20 (Columbia — Augusta / Midlands corridor)

I‑20 carries heavy commuter and freight traffic through the Columbia metro and east toward the Midlands and can be hazardous where urban congestion meets high‑speed rural segments. Common crash types are rear‑end collisions in backups, left‑turn and ramp‑related impacts at busy interchanges, and work‑zone incidents. Injuries range from soft‑tissue harm to catastrophic injuries in multi‑vehicle or truck crashes. Evidence such as traffic camera recordings, work‑zone logs, and medical records are often decisive; municipal or contractor liability can arise in poorly signed construction zones. If you were injured on I‑20, contact our personal injury lawyers at 843-352-4149 so investigators can preserve perishable records.

US‑17 / Coastal highways (Charleston — Myrtle Beach corridor)

US‑17 and other coastal highways mix local, tourist and commercial traffic and face unique hazards: narrow shoulders, frequent access points, pedestrian activity, and seasonal congestion. Common collisions include intersection and left‑turn crashes, pedestrian or bicycle strikes in town centers, and run‑off‑road incidents during storm or flooding events. Injuries to vulnerable road users are often catastrophic. When infrastructure, signage or poor lighting contributes, municipal records and surveillance footage can be key evidence. If you or a family member was injured on US‑17 or a coastal route, call Drennan Law Firm at 843-352-4149 to discuss your claim.

US‑501 / Ocean Boulevard corridor (Myrtle Beach / Grand Strand tourist routes)

US‑501 and Ocean Boulevard corridors around Myrtle Beach experience heavy seasonal tourist traffic, frequent lane changes, lots of pedestrian activity, and a high incidence of distraction‑related crashes. Typical wrecks include rear‑ends, intersection collisions, and vehicle‑vs‑pedestrian incidents, often producing fractures, head injuries and significant soft‑tissue damage. Preservation of business surveillance, pedestrian crosswalk studies, and police reports is essential in building claims in this area. If you were injured on US‑501 or Ocean Boulevard, contact our lawyers at 843-352-4149 for a free consultation.

Avoiding Accidents

When navigating our highways, be especially careful when entering into bigger towns and cities where traffic becomes more condensed. When vehicles get closer together and there are more exits and complications, the chance of an accident increases significantly. Always keep a reasonable distance between yourself and other vehicles, and drive defensively at all times.

Fight For Your Compensation

No matter how careful you are, however, sometimes accidents are unavoidable, especially when caused by another driver who is driving intoxicated or distracted.

At Drennan Law Firm, we represent clients throughout the area, as well as out-of-state drivers who have been in accidents. We handle everything from whiplash to the most catastrophic head-on collisions and fatal accident claims.
