Partially Open
Provincial Highways 8, 9, and 14A Traffic Control Information (October 2025)
Provincial Highway 8 (Central Cross-Island Highway, Dayuling → Taroko Entrance) Traffic Control Measures for November 2025
Partial Openings | Controlled Construction | Nighttime Road Closures
Since the April 3, 2024 earthquake, the Taroko Maintenance Section of the Eastern Region Branch, Directorate General of Highways (DGH), has been balancing reconstruction progress with the transportation and livelihood needs of local residents and industries. At the end of each month, the Section convenes residents, community organizations, local businesses, relevant agencies, and civil/geotechnical engineering consultants familiar with the Central Cross-Island Highway to discuss and finalize the following month’s traffic control plan.
However, due to the overflow of the Swallow Grotto Landslide-Dammed Lake in October, which flooded the Jinheng Tunnel and Ludan Bridge sections of the highway, the November 2025 traffic control measures will follow the previous month’s resolutions as listed below.
I. Guanyuan → Tinaxiang (114.6 km – 167.3 km)
After daily morning patrols and rockfall clearing confirm safety, the road will be open 06:00 – 16:30.
16:30 – 18:30: Control gates at 114.6 km (Guanyuan / Hehuan Police Station) and 167.1 km (Tinaxiang, west end) will be closed; vehicles may exit only, no entry.

III. Temporary or Mobile Work Zones
For temporary works such as asphalt milling and paving, control measures will be adjusted in coordination with nearby work zones and the Guanyuan, Tinaxiang, or Taroko control gate release times. Dynamic short-term traffic control may be implemented to minimize disruption. Separate announcements will be made if additional control measures are required.
Important Reminder for Drivers

Eastbound (Dayuling → Taroko): It is recommended to reach Tinaxiang before 17:00 to avoid missing the 17:30 release.
Westbound (Taroko → Dayuling): It is recommended to pass the Shakadang Tunnel east portal before 15:00 to avoid missing the 16:30 westbound release at Guanyuan.
⚠️ Due to ongoing slope stabilization and road repairs, traffic release times may be delayed or cancelled without notice due to weather or emergencies. Drivers should plan accordingly and check for real-time updates.
