Road Control on the KOM Route: When the Highway Opens and Why You Cannot Ride at Night

By Sean (seh STUDIO) · Updated 2026-09-14

The east approach to Wuling, the Taiwan KOM Challenge course starting in Hualien, runs through a construction control zone on Highway 8. The road is open, not severed, but when you can pass and for how long is set by published time slots, and the two halves of the zone follow completely different rules. This page lays out the hours in the September 2026 notice, the waiting points along the way, and the same restrictions your support vehicle is under, so you know which plans are simply not possible before you build an itinerary.

The Single Most Important Point: You Cannot Ride This Road at Night

The construction control zone on Highway 8 closes completely from 18:30 until 06:30 the next morning. You will occasionally see the suggestion that waiting for daytime slots is a hassle so it is easier to ride at night. Under the current notice that does not work. The road is fully closed after dark, and your support vehicle cannot get in either.

Before that there is a clearing period: 18:00 to 18:30 on the eastern section (Tianxiang to the Taroko entrance) and 16:30 to 18:30 on the western section (Guanyuan to Tianxiang). During those windows the zone is exit-only. In practice this means you must be past Guanyuan by 16:30, or you are not getting up the mountain that day.

Two Sections, Two Sets of Rules, Do Not Merge Them Into One Table

The notice treats the highway as two separate sections with very different rules. The eastern half is a case of only a few minutes being usable; the western half is open all day but with waiting points along the route. Reading the two sets of hours as one schedule is the fastest way to build an itinerary that cannot work.

The eastern section has five release windows a day. Two of them, 10:00 to 10:05 and 15:00 to 15:05, are only five minutes long. In practice only the 90-minute window at 06:30 and the two hour-long windows at midday and early evening are worth planning around.

The Western Section Is Open in Daylight, but There Are Four Waiting Points

The western section is two-way, so you do not have to catch a window for the section as a whole. But there are four separate construction points along it, each releasing traffic on its own schedule. Allow extra time for waiting, and accept that the total cannot be calculated precisely.

Note that the five windows at Huoranting are not the same as the five on the eastern section: the 09:45 and 14:45 slots each differ by 15 minutes. The two tables look alike and must not be used interchangeably.

Route Profile: Which Climb Falls Under Which Rule

From Qixingtan the first 25 kilometres are almost flat; the real climbing starts at the Taroko entrance. From 60 metres above sea level to 3,275 metres at Wuling, the route gains over 3,200 metres in 78 kilometres. The two background colours below match the two control regimes described above.

Laying the terrain over the control makes one thing obvious: the heaviest climbing, Tianxiang up to Dayuling, sits entirely inside the western section, and that section has no single release window to wait for, only four separate construction points along the way.

Can You Still Do It in One Day Under These Rules

Yes, but there is only one way to do it: take the first 06:30 window at the Taroko entrance, use those 90 minutes to clear Tianxiang, ride the western section through the day, and be past Guanyuan before 16:30. After Dayuling you join Highway 14A to Wuling, which is outside the scope of this notice.

There is not much margin in that plan. Tianxiang to Guanyuan climbs close to 1,900 metres and you still have to absorb the waiting time at four construction points. If you are not confident about that, or you would rather not have the whole day dictated by the clock, there are two alternatives: enter on the 17:00-18:00 window and stay overnight at Tianxiang, then start at 06:30 with a full day ahead of you; or switch to the western approach from Puli, which avoids this control entirely.

Your support vehicle is under the same control and cannot follow you freely. This is the part people most often overlook when planning: the vehicle cannot be where you need it when you need it, so supplies and spares have to be distributed in advance.

This Page Will Go Out of Date: Two Things We Have Not Confirmed

Control hours are published month by month. Everything on this page comes from the September 2026 notice, and the Huoranting windows only run to 24 September. If your trip falls in October or later, look up that month and do not reuse this page.

One more thing we have not verified: we did not find any exemption for bicycles or slow vehicles in the text of the notice. Some controlled sections treat slow vehicles differently from cars, but until that is confirmed with the authority, plan on the assumption that bicycles are controlled the same as cars.

Checking again a week before departure is the cheapest insurance. The sources we use are listed below.
