Seoul fireworks festival 2026 subway: what changes tonight
The main fireworks run from 20:00 to 21:10 on Saturday, September 5, over the Han River between Mapo Bridge and Hangang Railway Bridge.
This is the 70-minute core of a much longer day: the festival grounds open at 13:00 and citizen programs, food trucks, and stage events run until 22:00.
The festival runs for two days for the first time this year, with an eve event on Friday, September 4.
Teams from Korea, the USA, and the UK shoot under the theme ‘Your Infinite Colors’.
Events and food truck zones open at both Yeouido and Ichon Hangang Park, so the riverside is busy on both banks.
City officials expect about 1 million visitors across the evening.
If the goal is only the fireworks, arriving well before the 20:00 launch is enough to find a riverside spot.
Seoul’s official announcement carries the full schedule and venue map.

Subway changes tonight: extra trains on Lines 5 and 9
Seoul Subway Lines 5 and 9, the two lines that serve Yeouido, run additional trains during the festival.
The city also adjusts bus routes and Hangang water bus operations during both the eve event and the main show.
Shared bikes and electric scooters stop working in the area, so a Ttareungyi shortcut home is not an option tonight.
Wonhyo Bridge and Yeouido-ro are under full traffic control on September 5, and roads around the venue allow walking only in the core area.
In practice this means walking is the default inside the festival zone, and the subway is the only realistic way out for most people.
The city’s traffic measures cover bus, subway, and road changes in one notice.
Check a real-time map app before leaving, because individual bus detours change through the evening.
Crowd control: 6,800 staff and heavier fences
About 6,800 safety personnel are stationed at the venue and at nearby subway stations for both days.
That is roughly one staff member for every 147 expected visitors, and police, fire teams, and four district offices run a joint safety headquarters.
Safety fences and equipment increased 20 percent compared to last year.
This scale matters for one practical reason: after the 21:10 finale, the crowd moves toward the stations at once, and the areas around Yeouido-side stations are the choke points.
Prior editions saw the heaviest crowding around the stations closest to the park, and station-level 2026 guidance was not published in advance.
Waiting a while after the finale, or walking to a station further out, shortens the wait at the gates.
The staff at fences and station entrances can point to the less crowded exit on the spot.
How to get out: three exit plans for tonight
Plan one is to wait out the peak.
Stay by the river or at a food truck until about 22:00, then board when platforms have thinned.
Plan two is to walk away from the core before boarding.
A 20 to 30 minute walk along the river or toward the next districts puts access to stations outside the tightest control zone.
Plan three is to leave before the finale.
Leaving a few minutes before the finale from a spot slightly away from the river trades a small loss of view for a much shorter line.
Fences, closed roads, and one-way crowd flows mean the route in is not always the route out, so follow on-site guidance rather than the map line.
Taxis cannot reach the core area while Wonhyo Bridge and Yeouido-ro are controlled, so booking a ride from a pickup point outside the zone is the workable version.
Phone networks slow down when a million people share the same towers, so agree on a meeting spot with your group before the show starts.

Day-of tips for foreign visitors
- Use a T-money card or a charged transit app; cash lanes slow down when platforms are packed.
- Arrive by 19:30 for a riverside spot if the fireworks are the only goal.
- Do not rely on shared bikes or scooters near the venue; they are suspended during the event.
- Follow fence lines and staff directions on foot; some roads allow walking only.
- Set a group meeting point before 20:00, when phone networks get crowded.
FAQ
Q. Until what time is Line 5 service extended tonight?
No confirmed last-train times or extension schedule for the night of September 5, 2026, were published in the sources used here. Lines 5 and 9 do run additional trains during the festival, and the Seoul Metro real-time notice is the place to check before boarding.
Q. Which station should I use instead of Yeouido after the show?
No official 2026 station-by-station list was published in advance. The confirmed pattern is that stations nearest the park face the heaviest crowding, so walking 20 to 30 minutes to a station outside the core area, or waiting out the peak, shortens the wait.
Q. How long do the road controls on Wonhyo Bridge and Yeouido-ro last?
The full control on September 5 is confirmed, but exact start and end hours were not published in the retrieved sources. Treat those crossings as closed to vehicles for the evening and plan around them.
