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).
