Provincial Highway 8 – Central Cross-Island Highway

November Traffic Control Measures for the Eastern Section (Dayuling–Taroko Entrance)

Since the April 3, 2024 earthquake, the Taroko Maintenance Section of the Eastern Region Branch, Highway Bureau, has continued emergency repairs and reconstruction while taking into account the needs of local industries and road users. In the latter part of each month, it invites residents of the Greater Tianxiang area, industry associations, businesses, representatives of relevant agencies, and civil/geotechnical engineering consultants familiar with the Central Cross-Island Highway to discuss traffic control measures for the following month. Following the meeting held on October 29, the traffic control measures for November 2026 are as follows:

1. Guanyuan–Tianxiang (Provincial Highway 8, km 114.6–167.1)

(1) Traffic opening hours: Two-way traffic is permitted daily from 06:30 to 16:30. Control points: west end, in front of the Guanyuan Hehuan Police Station at km 114.6; east end, Tianxiang at km 167.1.

(2) Road clearance period: 16:30–18:30 daily. No vehicles may enter the controlled section; vehicles already inside may exit only.

(3) Nighttime closure: The road is closed daily from 18:30 to 06:30 the following day.

(4) Construction control sections: Mobile traffic control will be implemented at km 112.6 (Dayuling section), km 116.5 (Guanyuan section), km 140 (Xinbaiyang section), km 153.8 (Luoshao section), and km 157.7 (Horan Pavilion section).

2. Tianxiang–Taroko Entrance (Provincial Highway 8, km 167.7–184.5)

(1) Traffic opening hours: Traffic will be released in both directions in five scheduled periods daily between 06:30 and 18:00: 06:30–08:00, 10:00–10:05, 12:00–13:00, 15:00–15:05, and 17:00–18:00. Control points: west end, at the Lushui Shuiwen Bridgehead at km 169.5; east end, east portal of Shakadang Tunnel.

During each release period, the work zones on both sides will coordinate with one another. As a general rule, all vehicles that have arrived and are waiting at both ends of the work zones before the release will be allowed to pass before construction traffic control resumes.

(5) Traffic diversion: Traffic between Taroko Entrance and Changchun Tunnel will continue to be diverted as follows:

Westbound (Taroko to Tianxiang): Shakadang Tunnel (Taroko N. P. HQ) → Xila'an Tunnel → Changchun Tunnel (Provincial Highway 8) → Tianxiang.

Eastbound (Tianxiang to Taroko): Provincial Highway 8 → Changchun Tunnel → Taroko Entrance.

3. Other Temporary or Mobile Work Zones

For other temporary or mobile works, such as asphalt pavement milling and resurfacing, nearby work zones and the scheduled traffic release times at Guanyuan, Tianxiang, and Taroko Entrance will be taken into consideration. To minimize disruption, short-duration mobile traffic control may be implemented, or separate control measures will be announced.

Travel Advisory

The Taroko Maintenance Section reminds motorists traveling from Dayuling to Taroko Entrance (approximately 74 km) to plan their journeys carefully. Eastbound (Dayuling to Taroko): Arrive at Tianxiang no later than 17:00 to catch the final release period, 17:00–18:00. Westbound (Taroko to Dayuling): Pass the traffic control station at the east portal of Shakadang Tunnel no later than 15:00 to ensure that you can pass the Guanyuan control point before the 18:00 nighttime closure.

The eastern section of the Central Cross-Island Highway (Provincial Highway 8) continues to undergo disaster-recovery works on slopes, roadbeds, and pavement damaged by the earthquake and typhoons. Traffic releases may be delayed or cancelled due to weather or unforeseen circumstances. Please plan ahead, prepare contingency arrangements, and monitor weather forecasts and road control/access information.
