Provincial Highways 8, 9, and 14A Traffic Control Information (July 2025)

Provincial Highway 8 (Central Cross‑Island Highway, Dayuling → Taroko Entrance)
Traffic Control Measures for July 2025

Since the 3 April 2024 earthquake, the Taroko Maintenance Section of the Eastern Region Branch, Directorate General of Highways (DGH), has balanced emergency reconstruction with the transportation and economic needs of local communities. At the end of each month, the Section convenes Tinaxiang‑area residents, businesses, civic groups and related agencies to decide the traffic plan for the coming month.
The following control measures apply throughout July 2025 (ROC 114):
I. Guanyuan → Tinaxiang (114.6 km – 167.3 km)

After the daily dawn patrol and rockfall clearing confirm that the road is safe, traffic is open 06:00 – 16:30.

16:30 – 18:30: gates at 114.6 km (Guanyuan / Hehuan Police Station) and 167.3 km (Tinaxiang, west end) are closed – exit only, no entry.

18:30 – 06:00 the next morning: full nighttime road closure.

Work‑zone traffic control within this section
Kilometre Location (section) Control
118.3 km Guanyuan section dynamic traffic control
138.9 km Xinbaiyang section dynamic traffic control
147.8 km Hualu River section hourly 10‑min openings on the hour
157.7 km Huoran Pavilion section dynamic traffic control
II. Tinaxiang → Taroko Entrance (167.7 km – 184.5 km)

After the morning patrol confirms safety, five daily release windows are provided:
06:30 – 08:00 • 10:00 – 10:05 • 12:00 – 13:00 • 15:00 – 15:05 • 17:00 – 17:30.
For the short 10:00 and 15:00 releases, only vehicles already waiting at the control point gates may pass.

17:30 – 18:30: at the control point gates at 167.7 km (Tinaxiang, east end) and the Shakadang Tunnel east portal are closed – exit only, no entry.

18:30 – 06:30 the next morning: full nighttime road closure.

Dynamic Traffic control Zones (08:00 – 16:00 daily)

175.7 km – Jinheng Tunnel section

179.5 km – west end of Baisha No. 1 Bridge

180.5 km – west end of Ning’an Bridge

183.1 km – near Changchun Bridge
 Both ends coordinate so that all vehicles waiting at the checkpoints pass before the road is closed again.

One‑way split traffic between Taroko Entrance and Changchun Tunnel

Westbound (Taroko → Tinaxiang): Shakadang Tunnel → Xila’an Tunnel → Changchun Tunnel → Tinaxiang.

Eastbound (Tinaxiang → Taroko): Provincial Hwy 8 → Changchun Tunnel → Taroko Entrance.

III. Other temporary / Dynamic Traffic Control Work Zone

Short‑duration controls (e.g., asphalt milling and paving) will be scheduled to coincide with the above release windows to minimize disruption. Separate announcements will be issued if necessary.
Important reminder for drivers (full 74 km Dayuling → Taroko road section)

Eastbound (Dayuling → Taroko): reach Tinaxiang before 17:00 to avoid missing the 17:00 – 17:30 release.

Westbound (Taroko → Dayuling): pass the Shakadang Tunnel east portal by 15:00 to avoid missing the 16:30 westbound entry closure at Guanyuan.

Because multiple slope‑stabilization and roadway repairs are still under way, release times may be delayed or cancelled at short notice due to weather or emergencies. Plan extra time, monitor weather and road reports, and use:
