Columbia, SC’s Highest-Crash Intersections and Roads: A Driver’s Guide

Columbia, South Carolina sits at the crossroads of three major interstate highways — I-20, I-26, and I-77 — and Richland County consistently ranks among South Carolina’s highest-crash counties. Richland County, where most of Columbia is located, recorded 12,068 traffic collisions in 2024 — the third-highest total of South Carolina’s 46 counties, behind only Greenville and Charleston — including 60 fatal collisions in which 64 people died (SCDPS Traffic Collision Fact Book, 2024 edition). Certain Columbia intersections and highway interchanges are responsible for a disproportionate share of those crashes, and drivers who travel these routes daily face elevated risks of serious injury. If you have been hurt in a crash at one of Columbia’s highest-crash intersections, understanding your rights under comparative negligence law is critical to recovering fair compensation.

Why Columbia’s Roads Are Among the Most Crash-Prone in South Carolina

Columbia’s unique geographic position as the state capital and the hub of South Carolina’s interstate system creates traffic patterns that few cities of its size must manage. Three major interstates converge around the city, and SCDOT says the I-20/I-26 junction known as “Malfunction Junction” “no longer meets the demands of modern traffic.” The stretch of I-26 between St. Andrews Road and I-20 carried 143,900 vehicles a day in 2025 (SCDOT traffic counts).

Beyond the interstates, Columbia’s surface street network presents its own challenges. Many of the city’s busiest arterials — Two Notch Road, Broad River Road, Assembly Street, and Garners Ferry Road — carry about 20,000 to 50,000 vehicles a day (SCDOT, 2025). Rapid suburban growth in areas like Northeast Columbia, Irmo, and Lexington has pushed commuter traffic into corridors that lack adequate turn lanes, pedestrian infrastructure, and modern signal timing.

The presence of the University of South Carolina campus near downtown adds another layer of complexity. Thousands of students on foot, on bicycles, and on scooters share roads with heavy commuter traffic, particularly along Assembly Street, Gervais Street, and Blossom Street. Pedestrian accidents near campus are a persistent and serious problem.

The Highest-Crash Intersections in Columbia, SC

In this guide, “dangerous” means high crash counts in South Carolina Department of Public Safety (SCDPS) data. SCDPS publishes each county’s five highest-crash intersections every year: the I-20/I-26 interchange, I-20 at Broad River Road, and SC-12 at I-77 appear in those tables (SC-12 in 2023 only). The others are busy commercial intersections for which the state publishes no intersection-level counts. The numbering is not a ranking.

1. I-20 and I-26 Interchange (“Malfunction Junction”)

The I-20/I-26 interchange sits at the geographic center of South Carolina’s interstate system and has earned the nickname “Malfunction Junction” for good reason. In 2024 the I-20/I-26 interchange recorded 124 collisions on the Lexington County side, one of them fatal, and 95 more on the Richland County side (SCDPS Traffic Collision Fact Book, 2024 edition). The interchange’s tight curves, short merge zones, and the sheer volume of traffic — including heavy commercial truck traffic — create conditions where rear-end and sideswipe collisions are common. Truck accidents at Malfunction Junction are especially devastating due to the speed and weight of commercial vehicles navigating the interchange’s complex lane configurations.

2. I-20 and US-176 (Broad River Road)

The combination of interstate on-ramp and off-ramp traffic merging with heavy Broad River Road commercial traffic creates constant conflict points. Drivers exiting I-20 at highway speed into congested surface-street traffic are a common source of rear-end collisions at this location. It was Richland County’s highest-crash intersection in 2023 and 2024 — 224 collisions in 2024, second-most in South Carolina, none of them fatal (SCDPS). SCDOT rebuilt the interchange under its Carolina Crossroads program, and the new layout was fully operational in fall 2025.

3. Two Notch Road and Sparkleberry Lane Extension

The Northeast Columbia corridor along Two Notch Road has experienced explosive commercial growth, including around the intersection at Sparkleberry Lane Extension. Heavy traffic from the Village at Sandhill shopping district, combined with commuters traveling between Northeast Columbia and downtown, creates gridlock conditions that can lead to aggressive driving, red-light running, and failure-to-yield collisions.

4. Assembly Street and Gervais Street

Located in the heart of downtown Columbia, this wide, multilane intersection mixes heavy vehicle traffic with frequent pedestrian crossings, raising the risk of side-impact collisions and pedestrian accidents. Drivers running red lights and failing to watch for crosswalks are persistent problems. The intersection’s proximity to the South Carolina State House, University of South Carolina, and the Main Street entertainment district means that pedestrian traffic is heavy throughout the day and into evening hours. Bicycle riders navigating between campus and downtown are also at elevated risk at this intersection.

5. SC-12 (Percival Road) at I-77

This interchange recorded 116 collisions in 2023 — third in Richland County — including one fatal crash in which one person died, and 29 people injured (SCDPS Traffic Collision Fact Book, 2023 edition); in 2024 it dropped out of the county’s top five. The interchange handles heavy commuter traffic between East Columbia and the I-77 corridor leading to Rock Hill and Charlotte, and the merging patterns at the on-ramps create dangerous speed differentials between highway and surface-street traffic.

6. Garners Ferry Road and Leesburg Road

This intersection in Southeast Columbia sits at the junction of two heavily traveled corridors — about 50,000 vehicles a day use Garners Ferry Road here (SCDOT, 2025). The combination of commercial traffic and residential commuters creates congestion that can lead to rear-end collisions and T-bone crashes, particularly during morning and afternoon rush hours. Victims of crashes here may suffer traumatic brain injuries or spinal cord injuries that require long-term medical care.

7. Broad River Road and Bush River Road

The meeting of two busy arterials near I-20 and Dutch Square creates heavy turning traffic. The multiple turn lanes and the constant flow of vehicles entering and exiting shopping centers generate conflict points that can produce angle collisions and sideswipe crashes throughout the day.

Columbia’s Highest-Crash Highways and Corridors

Interstate 20

I-20 had more fatal crashes than any other interstate in the Columbia area: 35 in Richland and Lexington counties between 2020 and 2024, against 31 on I-77 and 30 on I-26 (NHTSA Fatality Analysis Reporting System). Within Richland County alone, I-20 accounted for 21 fatal crashes and 25 deaths over those five years. Statewide, SCDPS recorded 2,155 collisions on I-20 in 2024, including 15 fatal collisions that killed 18 people (SCDPS Traffic Collision Fact Book, 2024 edition). The highway carries heavy long-distance commercial truck traffic between Atlanta and I-95 at Florence, and the interchanges within Columbia — particularly at I-26, Broad River Road, and Monticello Road — are where the heaviest crash concentrations occur.

Two Notch Road (Full Corridor)

Two Notch Road stretching from downtown Columbia northeast to the Sandhills area is one of the metro’s most consistently dangerous corridors: US-1, which carries Two Notch Road, was Richland County’s highest-crash roadway in 2023 and 2024, with 944 collisions in 2024 (SCDPS). The road’s transition from a dense urban street to a high-speed suburban arterial — combined with dozens of unsignalized commercial driveways — creates dangerous conditions for the length of the corridor.

Broad River Road

Broad River Road from downtown Columbia northwest to Irmo and the Lake Murray area crosses both I-20 and I-26 at Richland County’s two highest-crash intersections (SCDPS, 2024). The corridor’s mix of heavy commercial development, residential neighborhoods, and school zones creates hazards along its length. Motorcycle riders are vulnerable here, where other drivers can fail to see smaller vehicles in heavy traffic.

Common Causes of Intersection Crashes in Columbia

Understanding what causes intersection crashes helps victims identify the at-fault party and build a strong injury claim:

• Red light running: Disregarding signs and signals was one of the five most-cited crash factors in Richland County in 2024 (SCDPS). Drivers who enter an intersection after the light has turned red cause violent T-bone collisions that frequently result in catastrophic injuries.
• Failure to yield: Failure to yield the right of way was the second most-cited crash factor in both Richland and Lexington counties in 2024 (SCDPS) — left turns across oncoming traffic are a classic example.
• Distracted driving: Cell phone use, GPS navigation, and infotainment system distractions cause drivers to miss traffic signals and other vehicles in intersections.
• Aggressive driving and speeding: The chronic congestion on Columbia’s major corridors breeds frustration and aggressive driving behavior, including speeding through yellow lights, tailgating, and unsafe lane changes near intersections.
• Impaired driving: Late-night traffic around Columbia’s nightlife districts, including Main Street and Five Points, raises the risk of impaired-driving crashes.
• Dangerous road conditions: When a dangerous road condition — a malfunctioning signal, missing sign, or road defect the responsible agency knew or should have known about — contributes to a crash, the agency may be liable under the South Carolina Tort Claims Act, but not for the highway’s design itself (S.C. Code § 15-78-60(15)).

South Carolina Laws That Protect Accident Victims

These South Carolina rules shape an accident claim in the Columbia area.

Statute of limitations: South Carolina gives accident victims three years from the date of injury to file a personal injury lawsuit under S.C. Code § 15-3-530. Missing this deadline typically bars your claim entirely.

Comparative fault: South Carolina follows a modified comparative fault rule. You can recover compensation if you are less than 51% at fault for the accident, but your award is reduced by your percentage of responsibility. Insurance companies aggressively argue comparative fault to reduce what they owe, making strong evidence collection essential.

Right-of-way laws: S.C. Code § 56-5-2310 through § 56-5-2350 govern right-of-way rules at South Carolina intersections. Violations of these statutes — such as failing to yield to oncoming traffic when making a left turn — constitute negligence per se, which can establish the other driver was negligent — though you must still show the violation caused your injuries.

Uninsured motorist coverage: South Carolina requires drivers to carry uninsured motorist coverage under S.C. Code § 38-77-150, which protects you if the at-fault driver has no insurance or flees the scene. Underinsured motorist coverage, for a driver whose limits are too low, is optional (S.C. Code § 38-77-160). This coverage is especially important at high-crash intersections where hit-and-run incidents occur.

What to Do After an Intersection Accident in Columbia

The actions you take immediately after a crash at one of Columbia’s dangerous intersections can significantly impact your ability to recover full compensation:

1. Call 911 and request police and medical response. South Carolina law requires you to notify police immediately after a crash that injures or kills anyone (S.C. Code § 56-5-1260). If no officer investigated a crash involving injury or $1,000 or more in property damage, the driver or owner must file a written report with the DMV within 15 days (S.C. Code § 56-5-1270). The police report is key to your insurance claim, although South Carolina does not allow it as evidence of fault at trial (S.C. Code § 56-5-1290).
2. Seek medical treatment immediately. Even seemingly minor symptoms can indicate serious injuries like traumatic brain injuries or internal bleeding. Delaying treatment creates gaps in your medical records that insurance companies will exploit.
3. Document everything. Photograph vehicle damage, the intersection layout, traffic signals, road conditions, skid marks, and your injuries. Note the time of day, weather conditions, and traffic signal status at the time of the crash.
4. Collect witness information. Get names and phone numbers from anyone who witnessed the crash. Eyewitness testimony can be crucial in establishing who had the right of way.
5. Do not admit fault. Anything you say at the scene can be used against you in a comparative fault analysis. Let the investigation determine liability.
6. Contact a Columbia car accident lawyer before speaking with any insurance adjuster. Insurance companies often contact crash victims within days seeking recorded statements designed to minimize your claim.

Proving Fault at Columbia’s Dangerous Intersections

Establishing liability after an intersection crash in Columbia requires building a comprehensive evidence portfolio. An experienced attorney will pursue:

• Video footage: SCDOT’s traffic cameras stream live and do not record, so footage usually comes from nearby businesses, dashcams, or doorbell cameras — and it must be requested quickly before it is overwritten.
• Police accident report: The investigating officer’s report includes witness statements, diagrams, citations, and a fault determination that carries significant weight in settlement negotiations, though the report itself and any traffic conviction are inadmissible as proof of fault at trial (S.C. Code §§ 56-5-1290, 56-5-6160).
• Accident reconstruction: In serious cases, expert reconstructionists analyze vehicle damage, road markings, and physics to determine exactly how the collision occurred and who is responsible.
• Cell phone records: Subpoenaed phone records can prove the at-fault driver was texting, calling, or using social media at the time of the crash.
• Road maintenance records: If a maintenance failure or a malfunctioning signal contributed to your crash, records from SCDOT or Richland County may show the government entity knew about the hazard and failed to correct it.
• Black box data: Modern vehicles record speed, braking, and steering data that can be extracted to prove exactly what the at-fault driver was doing in the seconds before impact.
