Can the cars in Tongmai section of National Highway 3 18 pass?

Yes ~ but drive slowly ~ speed limit ~ that section is dangerous. . .

Cycling is not recommended in the south of Sichuan-Tibet line ~ You can go to the next tour app~ There are many car owners posting motorcades on Sichuan-Tibet line and Qinghai-Tibet line ~ It is convenient to check the road conditions immediately ~

Road conditions of the southern section of the Sichuan-Tibet line:

1, Chengdu-Ya 'an, high speed, very good (14 1KM).

2. Ya 'an-Shimian-Kangding (due to the poor road conditions of Erlangshan Tunnel), it is suggested that the road conditions from Shimian to Hailuogou are good, basically asphalt (290KM), the driving time from Ya 'an to Shimian is about 2.5 hours, and the driving time from Shimian to Kangding is about 3.5 hours.

3. Kangding-Zheduo Mountain, asphalt road has been repaired, 40KM, all uphill (40 km).

4. Zheduo Mountain-xinduqiao, asphalt pavement. 40 km downhill (40 km).

Driving time from Kangding to xinduqiao: about 2 hours.

5. xinduqiao-Yajiang, except Yakou section 18km rotten road, the rest are asphalt roads. Gaoersishan Tunnel will be opened to traffic at the bottom of 15(70km).

6. Yajiang-Litang, the whole journey 135km, and the driving time is 4 hours. The top Wanshan tunnel has been opened to traffic, but the tunnel about 3 kilometers away from Litang has not been opened to traffic. It is expected to be open to traffic at the end of 2065, 438+05, and the road conditions at the old intersection are poor (135km).

7. Litang-Haizishan, with good asphalt road conditions (95KM).

8. Haizishan-Batang asphalt road, 99% of the road conditions are very good, and there are many tunnels. Special attention should be paid to dark ice (95KM) in special seasons.

Litang to Batang, the whole journey is 200KM, and the journey takes 3-4 hours.

9. Batang-Zhuka, asphalt road, many bends, narrow road surface, subgrade collapse in some places, so it is necessary to drive carefully (160KM).

Batang to Mangkang, 100 km, more than two hours' drive, enters the Tibet border at Jinsha River Bridge. Please prepare your ID cards, driver's licenses and driving licenses in advance, and provide your telephone numbers. After that, the Jinsha River Bridge reached Mangkang for more than 70 kilometers, with a speed limit of 2 hours and 40 minutes.

From Mangkang to Rumei, it is 60 kilometers, 20 kilometers uphill and 40 kilometers downhill. There are many bends, and there are two villages on the road. Please pay attention to pedestrians.

10, Zhuka-Zuogong, asphalt road, the famous Sanjiang exchange scenic spot, steep abyss, easy to fall rocks, narrow roads, difficult to meet cars, very thrilling, drive very carefully, the speed limit is 40 km/h (1 10KM). Zhuka-Zuogong, 65438+.

1 1, Zuogong-Bangda 90km, asphalt road, narrow road surface, good road conditions, speed limit section of 40km (90km) per hour.

12, Bonda-Basu, it's dangerous to turn 99 on asphalt road. Use the brakes less, put on the low gear and drive slowly. When there is water, try to cool the brakes and drive slowly.

16, Tongmai-Lulang, Earth-rock road, 30 km Tongmai natural barrier, the road condition is very poor, of which 14 km is the most dangerous, and the normal traffic time is two hours. I hope that riders can pass as soon as possible to ensure safety and smoothness. Because Tongmai is building tunnels and bridges, the road surface is more worn out. It is estimated that the tunnel bridge will be fully completed in July 2065438 1 day, when the natural disaster in Tongmai will become history and the speed limit section will be (14 1KM).
