    Traffic Control Measures for January on the Eastern Section of the Central Cross-Island Highway (Provincial Highway 8: Dayuling–Taroko)

    Following the April 3, 2024 earthquake, the Taroko Work Section of the Eastern Region Branch, Highway Bureau, MOTC, has been coordinating emergency repairs and reconstruction while also considering local transportation and industrial needs.
    Since the disaster, coordination meetings have been held in the latter part of each month, inviting residents of the Greater Tianxiang area, community groups, enterprises, relevant agencies, and civil/geotechnical engineering consultants familiar with the Central Cross-Island Highway to jointly discuss traffic control measures for the following month.

    After discussion at the meeting held on December 26, the traffic control measures for January of January 2026 have been determined as follows:

    I. Guanyuan to Tianxiang (Provincial Highway 8, 114.6 km–167.3 km)

    Daily road inspection and rockfall clearance will be conducted in the morning. Once conditions are confirmed safe for travel, the road will generally be open from 07:00 to 16:30.
    From 16:30 to 18:00, the control gates at 114.6 km (in front of Guanyuan Hehuan Police Station) and 167.1 km (western end of Tianxiang) will be closed, prohibiting vehicle entry (exit only, no entry between Guanyuan and Tianxiang).
    From 18:00 to 07:00 the following day, the road will be fully closed at night (Guanyuan–Tianxiang section closed).

    Construction-related traffic control between Guanyuan and Tianxiang includes one work zone at 117.4 km (Guanyuan section).
    Passage will generally be released five times daily at:

    07:00–08:00
    10:00
    12:00–13:00
    15:00
    16:30

    II. Tianxiang to Taroko Entrance (Provincial Highway 8, 167.7 km–184.5 km)
    After daily morning inspections and rockfall clearance, and once conditions are confirmed safe, traffic will be released five times daily between 07:00 and 17:30, at:
    07:00–08:00
    10:00–10:05
    12:00–13:00
    15:00–15:05
    17:00–17:30

    From 17:30 to 18:00, control gates at 167.7 km (eastern end of Tianxiang) and the eastern entrance of the Shakadang Tunnel (Taroko N. P. HQ) will be closed, prohibiting vehicle entry (exit only, no entry between Tianxiang and Taroko).
    From 18:00 to 07:00 the following day, the road will be fully closed at night (Tianxiang–Taroko section closed).

    At the following locations—155.8 km (Xuejiachang), 157.6 km (Huoran Pavilion), 172.3 km (west entrance of Jiuqudong Tunnel), 173.5 km (east entrance of Jiuqudong Tunnel), 174.8 km (east entrance of Zhuilu Tunnel), 176.8 km (west entrance of Jinheng Tunnel), and 180.5 km (west end of Ning’an Bridge)—traffic control will correspond to the five daily release periods between Tianxiang and the Taroko Entrance.
    Traffic will be managed dynamically. During each release period, all vehicles waiting at both ends of each work zone prior to the release will be allowed to pass before traffic control resumes.

    Between the Taroko Entrance and Changchun Tunnel, traffic will continue to be diverted as follows:

    Westbound (Taroko → Tianxiang):
    Shakadang Tunnel → Xila’an Tunnel → Changchun Tunnel (Provincial Highway 8) → Tianxiang

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

    III. Other Temporary or Mobile Work Zones

    Temporary or mobile construction (such as asphalt pavement milling and resurfacing) will be coordinated with nearby work zones and the scheduled release times at Guanyuan, Tianxiang, or the Taroko Entrance.
    Under the principle of minimizing traffic impact, short-term dynamic traffic control will be implemented, or separate announcements will be issued as necessary.

    Important Reminder

    For motorists traveling the Dayuling–Taroko Entrance section (approximately 74 km):

    Eastbound (Dayuling → Taroko): It is recommended to arrive at Tianxiang no later than 17:00, to avoid missing the final release period from 17:00 to 17:30.

    Westbound (Taroko → Dayuling): It is recommended to pass the control station at the eastern entrance of the Shakadang Tunnel by 15:00, to ensure clearing the Guanyuan control point before the 18:00 night closure.

    Due to ongoing earthquake- and typhoon-related repairs to slopes, roadbeds, and pavements, release times may be delayed or canceled because of weather conditions or unforeseen circumstances.
    Motorists are advised to plan ahead, stay flexible, and monitor weather forecasts and traffic updates.

    Partially Open
    Provincial Highway 14A (Mt. Hehuan Area)

    Forwarded from the Central Region Maintenance Branch, Highway Bureau

    According to information from the Central Weather Administration, due to the influence of a strong continental cold air mass, nighttime temperatures on high-altitude sections above 3,000 meters along Provincial Highway 14A are expected to drop below 0°C, with a high likelihood of snowfall and road icing.

    To ensure the safety of road users, a precautionary road closure will be implemented on Provincial Highway 14A from 18 km (Cuifeng) to 41.5 km (Dayuling) starting at 5:00 PM today (Jan. 8).
    During the closure, vehicles may exit but are not permitted to enter.
    In addition, due to the steep and winding terrain between 31.7 km (Wuling) and 32.7 km (Songxue Lodge), which is prone to skidding, this section will be placed under a full bi-directional closure, and all traffic will be prohibited.

    At 7:00 AM tomorrow (Jan. 9), the road will be reassessed based on weather and road conditions to determine whether to implement restricted access for vehicles equipped with snow chains or to fully reopen the road.

    Road users are advised to check weather forecasts and road conditions in advance, carry snow chains in their vehicles, and drive with caution at reduced speeds.

    Reminder to road users:
    Mountain weather conditions are severe and change rapidly. Traffic control sections and measures may be adjusted flexibly according to on-site conditions.
    In accordance with the 2026 Hehuanshan Snow Season Regulations, when snowfall or road icing occurs, Class A and B large passenger vehicles, trucks exceeding 3.5 tons, and all types of motorcycles (including large heavy motorcycles) are prohibited from entering controlled sections.

    Additionally, the Temporary Provincial Highway 8 Route 37 (Central Cross-Island Detour Road) will add a nighttime passage at 5:30 PM, exclusively for agricultural transport trucks from the Greater Lishan area, traveling from Deji toward Guguan.

    Motorists planning to travel on Provincial Highway 8 or Provincial Highway 14A are advised that road conditions in mountainous areas during the snow season are difficult to predict. Unless absolutely necessary, travel is not recommended. Before departure, please prepare appropriate personal equipment and snow chains, closely monitor weather forecasts and traffic information, and plan alternative routes in advance.

    For the latest road information, please tune in to Police Radio (FM 94.5) and pay attention to roadside Changeable Message Signs (CMS).
