View Seoul Traffic Cameras →Seoul is one of the most densely populated cities on Earth, with nearly 10 million residents packed into 605 square kilometers. The Seoul Capital Area — including Incheon and Gyeonggi Province — is home to roughly 26 million people, making it one of the world's largest metropolitan regions. This extraordinary density produces some of the most congested traffic corridors in Asia, particularly where expressways converge near the Han River crossings and southern business districts.
TrafficVision.Live aggregates live camera feeds from the Korea Expressway Corporation (KEC), ITS Korea, and Seoul's metropolitan traffic management center. Our platform provides access to 135,000+ cameras from 600+ sources across 130+ countries, with deep coverage of Seoul's urban expressway system and surface arterials.

Eastern Seoul including Olympic Park, Lotte World Tower vicinity, and Jamsil area. Cameras cover Songpa-daero, Olympic-ro, the Misari junction, and eastern approaches to the Seoul Ring Expressway. Key monitoring zone for traffic flowing toward Hanam and the Yeongdong Expressway.
Northern Seoul — 350+ Cameras
Covers Dobong, Nowon, Seongbuk, and Jungnang districts. Camera feeds monitor Bukbu Expressway approaches, Dobong IC, Suraksan tunnel corridors, and arterials connecting to Uijeongbu and northern Gyeonggi Province. Critical for commuter traffic flowing into central Seoul from the northeast.
Key Expressway Corridors
Seoul Ring Expressway (Route 100)
The Seoul Ring Expressway forms a 127-kilometer loop around the capital, functioning as the primary bypass and distribution route for the entire metropolitan area. With over 100 cameras positioned along its length, this is the most heavily monitored corridor in the Seoul network.
Critical Sections:
- Southern segment (Pangyo IC to Haman IC): Carries Gyeongbu Expressway overflow; severe congestion during evening rush
- Eastern segment (Hanam IC to Toegyewon IC): Mountain tunnels create bottlenecks; reduced speed zones
- Northern segment (Goyang to Uijeongbu): Connects to Bukbu Expressway and northern satellite cities
- Western segment (Gimpo to Gwangmyeong): Airport-bound traffic merges with industrial corridor flows
Ring Expressway Strategy
The Seoul Ring Expressway is divided into inner and outer loops. During peak hours, the inner loop (clockwise) typically moves faster on the southern segment, while the outer loop (counterclockwise) is faster on the northern segment. Use cameras to compare both directions before committing to a route around the city.
Olympic Expressway & Gangbyeon Expressway
These two expressways run parallel along the Han River — the Olympic Expressway on the south bank and the Gangbyeon Expressway on the north bank. Together, they form Seoul's most critical east-west corridor.
Olympic Expressway (South Bank):
- Connects Gimpo area to Gangdong, running through Yeouido, Banpo, and Jamsil
- Heavy congestion at Yeouido exits during financial district rush hours
- Hannam Bridge, the city's busiest crossing, handles over 192,000 vehicles per day on weekdays
- Banpo Bridge and Jamsil IC are persistent bottleneck zones
- Camera coverage at every on/off ramp and bridge approach
Gangbyeon Expressway (North Bank):
- Runs from Gayang Bridge to Misari, paralleling the Olympic Expressway across the river
- Mapo and Seongsu exits create severe merge congestion
- Ttukseom and Jamsildaegyo areas see heavy weekend recreational traffic
- Full camera coverage including tunnel approaches at Eungbong
Monitor Han River Corridor Conditions
The Olympic and Gangbyeon Expressways carry a combined 800,000+ vehicle movements daily. Use our interactive map to compare conditions on both banks of the Han River before choosing your east-west route through Seoul.
View Expressway Cameras →Gyeongbu Expressway Entry Corridor
The Gyeongbu Expressway (Route 1) is South Korea's most important highway, connecting Seoul to Busan over 416 kilometers. The Seoul approach section — from Yangjae IC through Gangnam — handles enormous daily volumes as commuters, intercity travelers, and freight traffic converge.
Yangjae IC is the primary chokepoint where the Gyeongbu Expressway transitions into urban Seoul. During evening rush, backup from Yangjae extends 15+ kilometers southward past Pangyo. Morning inbound traffic stacks from the Gangnam business district back through the interchange.
Naebu Expressway & Bukbu Expressway
Naebu Expressway cuts through central Seoul, connecting Seongsan Bridge in the west to Hanam IC in the east via a network of tunnels. Tunnel sections create unique challenges — incidents inside tunnels cause immediate severe delays with no alternate routing available. Camera coverage at tunnel portals and interior sections is essential for monitoring this route.
Bukbu Expressway runs north-south through eastern Seoul, connecting the Seoul Ring Expressway to the Gangbyeon Expressway. It serves as the primary route for northeast Seoul commuters and carries heavy traffic toward Namyangju and Guri.
Traffic Patterns and Peak Hours
Seoul's traffic congestion ranks among the worst globally. Understanding the patterns is essential for anyone navigating the city.
Morning Rush (7:00–9:30 AM):
- Inbound flows from Gyeonggi Province satellite cities (Bundang, Ilsan, Incheon) converge on all expressways
- Seoul Ring Expressway southern segment backs up from Pangyo through Yangjae
- Bukbu Expressway southbound queues extend past Uijeongbu
- Gangbyeon and Olympic Expressways see heavy westbound flows toward central Seoul
Evening Rush (6:00–9:00 PM):
- Extended duration — Seoul's evening rush lasts significantly longer than morning peak
- Gangnam district generates massive outbound flows in all directions
- Gyeongbu Expressway approach from Yangjae IC becomes gridlocked
- Han River bridge crossings slow to crawl as south-side workers head north
Friday Evening Exodus:
- Friday evening combines regular rush hour with weekend travel departures
- Gyeongbu Expressway (toward Busan/Daejeon), Yeongdong Expressway (toward Gangneung), and Seohaean Expressway (toward West Coast) experience 2-3x normal congestion
- Delays begin as early as 3:00 PM and persist past midnight on major holiday weekends
South Korea Road Safety
South Korea has faced challenges with high traffic fatality rates, particularly among senior citizens, who accounted for nearly 49% of all road deaths in 2023. Unlicensed driving remains a critical issue, contributing to over 400 deaths between 2021 and 2024. Real-time camera monitoring, combined with strict enforcement in the city's Green Transport Zones, is a vital tool for improving safety outcomes and reducing incident-related gridlock in the capital's high-density corridors.
Holiday Traffic — Chuseok and Lunar New Year
During Chuseok (Korean Thanksgiving) and Seollal (Lunar New Year), Seoul's expressway network reaches total gridlock. A drive from Seoul to Busan that normally takes 4 hours can take 10-14 hours. The exodus begins 2-3 days before the holiday. Monitor cameras continuously and consider departing very early morning (before 5 AM) or very late evening to avoid the worst congestion.
Weather Impacts on Seoul Traffic
Monsoon Season (June–September)
Seoul receives approximately 60% of its annual rainfall during the summer monsoon. Intense downpours regularly flood underpasses, low-lying expressway sections, and Han River bridge approaches.
High-Risk Flood Zones:
- Gangbyeon Expressway depressed sections near Ttukseom
- Olympic Expressway sections adjacent to Banpo Hangang Park
- Naebu Expressway tunnel portals and low-grade approaches
- Jamsu Bridge (submerges entirely during high water; designed to flood)
Use street cameras and expressway feeds to check for standing water, lane closures, and diversion points during heavy rain events. When the Han River level rises significantly, authorities close Jamsu Bridge and portions of the Gangbyeon Expressway preemptively.
Yellow Dust and Air Quality
Yellow dust (hwangsa) storms — fine particulate matter carried from Chinese and Mongolian deserts — periodically reduce visibility across Seoul. While these events don't typically close roads, reduced visibility on elevated expressway sections and bridge crossings warrants camera monitoring. During severe yellow dust warnings, traffic volumes often decrease as residents avoid driving, paradoxically improving road conditions.
Winter Cold and Snow
Seoul winters bring temperatures as low as -15C and occasional heavy snowfall. Camera feeds help monitor:
- Ice formation on elevated expressway sections and bridge decks
- Snow accumulation on northern mountain passes (Bukhansan area approaches)
- De-icing operations on Seoul Ring Expressway tunnel approaches
- Reduced visibility during snowfall events affecting Bukbu Expressway hillside sections
Typhoon Season
Late summer typhoons occasionally track through the Korean Peninsula. Strong winds can close Han River bridges and elevated expressway sections. Heavy rain combined with wind makes the Olympic and Gangbyeon Expressways particularly dangerous due to their riverside exposure.
Using TrafficVision for Seoul
Our platform offers several features particularly useful for navigating Seoul's complex road network.
Navigating Seoul's Districts
Seoul's 25 administrative districts (gu) each have distinct traffic characteristics. Gangnam-gu and Seocho-gu generate the heaviest business-district traffic. Jongno-gu and Jung-gu see government and tourism-related congestion. Mapo-gu and Yeongdeungpo-gu handle financial sector commuters. Songpa-gu experiences event traffic from Olympic Park and Lotte World.
Surface street cameras cover major arterials like Teheran-ro, Gangnam-daero, Sejong-daero, and Songpa-daero. These feeds are valuable for checking intersection-level congestion that expressway cameras cannot reveal — particularly useful around subway station exits during rush hours, where pedestrian and vehicle conflicts cause localized gridlock.
Seoul's traffic management center operates an adaptive signal system on major arterials. During peak hours, signal timing adjusts automatically based on real-time sensor data. Camera feeds let you verify whether these adjustments are effectively clearing congestion or if you should seek alternate routing through secondary streets.
Regional Connections
Seoul sits at the center of South Korea's expressway network, with major routes radiating outward to every part of the country.
- Gyeongbu Expressway (Route 1): Seoul to Busan via Daejeon and Daegu — the country's busiest intercity corridor
- Yeongdong Expressway (Route 50): Seoul to Gangneung on the East Coast — extremely heavy during ski season and summer beach travel
- Seohaean Expressway (Route 15): Seoul to the West Coast via Pyeongtaek and Seosan
- Gyeongin Expressway (Route 120): Seoul to Incheon — critical for airport access and port traffic
- Jungbu Expressway (Route 35): Seoul southward through central Korea

How do I find Seoul traffic cameras on TrafficVision?
Use the search bar to type "Seoul" or filter by country (South Korea) on our interactive map. You can also browse Seoul cameras in grid view, which lets you scan multiple feeds at once. All 2,500+ Seoul cameras are accessible free without any account or login required.
Do the cameras cover Korean expressways in real time?
Yes. Camera feeds from the Korea Expressway Corporation and ITS Korea update continuously. Expressway cameras along the Seoul Ring Expressway, Olympic Expressway, Gangbyeon Expressway, and Gyeongbu Expressway provide live imagery refreshed every few seconds, showing current traffic density, incidents, and weather conditions.
What are the worst times for Seoul traffic?
Morning rush runs from 7:00 to 9:30 AM, and evening rush extends from 6:00 to 9:00 PM — notably longer than most cities. Friday evenings are the worst regular occurrence, especially on expressways leading out of the city. Holiday periods (Chuseok and Lunar New Year) produce multi-day gridlock on all intercity expressways.
Can I see live Seoul street cameras and intersection feeds?
Yes. Beyond expressway cameras, TrafficVision includes hundreds of street cameras covering major arterial roads, intersections, and district-level streets across all 25 of Seoul's administrative districts. These feeds are especially useful for checking surface-street conditions when expressways are congested.
How do monsoon rains affect Seoul's expressway cameras?
Cameras remain operational during monsoon rains and are essential for checking flood conditions. Key areas to monitor include the Gangbyeon Expressway depressed sections, Jamsu Bridge (which submerges during high water), and Naebu Expressway tunnel approaches where flooding commonly blocks lanes. Authorities close affected sections proactively — cameras show closures in real time.
