Partial Opening | Controlled Construction | Nighttime Road Closures
Eastern Section of Provincial Highway 8 (Dayuling to Taroko Entrance)
Traffic Control Measures for June 2025 (Including the Dragon Boat Festival Holiday)
Since the April 3 Earthquake, the Taroko Maintenance Section of the Eastern Region Branch, Directorate General of Highways (DGH), has continued to implement post-disaster road repairs and reconstruction work along the eastern section of Provincial Highway 8. To balance repair progress with the transportation and economic needs of local communities, the Taroko Maintenance Section invites Tianxiang area residents, organizations, businesses, and related agencies to a coordination meeting at the end of each month to discuss traffic control measures for the upcoming month.
The following traffic control measures have been scheduled for June 2025 (including the Dragon Boat Festival holiday period):
Section 1: Guanyuan to Tianxiang (114.6km–167.3km)
Controlled Segment: Hehuan Police Station to Tianxiang
Based on daily morning road inspections and rockfall clearing, traffic will be permitted from 06:00 to 16:30, except at three major reconstruction sites.
From 16:30 to 18:30, entry gates at Hehuan Police Station (114.6km) and the west end of Tianxiang (167.3km) will be closed, and vehicles may exit only (no entry in either direction).
From 18:30 to 06:00 the next morning, the road will be fully closed to all traffic (nighttime closure).
The three major reconstruction sites at:
126.9km (near Sacred Tree)
134.8km (Xinbaiyang section)
158.8km (near Xibao)
will operate with scheduled hourly openings from 08:00 to 16:00.
Vehicles that arrive before the scheduled release time will be allowed through. The road will then close again immediately for continued construction.
Section 2: Tianxiang to Taroko Entrance (167.7km–184.5km)
Controlled Segment: Tianxiang to Taroko (east entrance)
Based on daily road conditions, five daily traffic release time will be provided:
07:00–08:00
10:00
12:00–13:00
15:00
17:00–17:30
For the 10:00 and 15:00 releases, only vehicles that arrive at the construction zones prior to the release will be allowed to pass.
At 17:30, entry gates at Tianxiang (167.7km) and the east entrance of the Shakadang Tunnel will be closed, and vehicles may exit only (no entry in either direction) until 18:30.
From 18:30 to 07:00 the following morning, the road will be fully closed (nighttime closure).
The three major construction sites at:
179.5km (west end of Baisha No. 1 Bridge)
180.5km (west end of Ning'an Bridge)
183.1km (near Changchun Bridge)
will operate with mobile traffic control from 08:00 to 16:00 daily. During traffic release periods, both ends of the site will coordinate to allow all vehicles waiting at the checkpoints to pass before the road is closed again.
Traffic between the Taroko Entrance and Changchun Tunnel remains under one-way control, as follows:
Westbound (Taroko to Tianxiang): Shakadang Tunnel → Xila'an Tunnel → Changchun Tunnel → Tianxiang
Eastbound (Tianxiang to Taroko): Provincial Highway 8 → Changchun Tunnel → Taroko Entrance
Section 3: Dragon Boat Festival Holiday (May 30–June 1)
During the Dragon Boat Festival holiday, the same traffic control measures as outlined above will be in place. However, all construction activities will be suspended along the route to allow smoother traffic flow through the reconstruction areas.
Section 4: Additional Temporary or Mobile Work Zones
Other construction activities, such as asphalt pavement milling and resurfacing, will be carried out with short-term mobile traffic controls. These controls will be coordinated with release times at Guanyuan, Tianxiang, and the Taroko Entrance to minimize disruption. Additional control measures will be announced separately if necessary.
Important Reminder for Road Users (74-kilometer Route from Dayuling to Taroko)
The Taroko Maintenance Section strongly advises drivers traveling the full route between Dayuling and the Taroko Entrance to plan their trips carefully:
Eastbound travelers (Dayuling → Taroko) should arrive at Tianxiang (167.7km) before 17:00 to avoid missing the final traffic release at 17:00–17:30.
Westbound travelers (Taroko → Dayuling) should enter at the Shakadang Tunnel checkpoint before 15:00 to ensure passing through the Tianxiang–Guanyuan section before the last westbound entry closure at 16:30.
Due to the extensive post-earthquake and typhoon recovery efforts along the eastern section of the Central Cross-Island Highway, many slope and roadbed repairs are still ongoing. If weather conditions worsen or emergencies arise, traffic releases may be delayed or canceled without prior notice. Road users are urged to stay updated with real-time road and weather information and make appropriate contingency plans.
Please refer to the DGH Real-Time Road Conditions Service website (https://168.thb.gov.tw), download the “Happy Road” mobile app, or listen to local traffic broadcasts for the latest updates. Drive with caution and stay safe.
