Tongmai Bridge Review

From Bomi to Nyingchi, Tongmai was once a national highway 318 on the sky risk, easy to landslides, mudslides, now Tongmai Bridge has been built, the sky is variable, the same location in different periods of three bridges people feel thousands of.

Tongmai Bridge is a throat project on the famous Tongmai Tianxian Road section of the 318 National Road South Line of Sichuan-Tibet Highway. Three cross-river bridges are distributed in the same location in different historical periods. The main open-tower Tongmai Bridge is a single-tower slant bridge. The two original seats have already suspended motor vehicle traffic.

Tongmai Bridge is a bridge on the 318 National Road Line. It is a cable-stayed bridge in the middle of Bomi to Bayi Town, Nyingchi City. It is very beautiful. It is said that this section of the road is very dangerous. This time, there is no feeling from here. It is very smooth.

The Tongmai Bridge of the three generations of the grandsons made Tongmai Tianxian no longer dangerous "Sichuan-Tibet difficulties, difficult to go to the West Tiantian". I have always heard such a sentence "I have not walked through the Tongmai Tianxian insurance of National Highway 318, I don't know the hardship of the Sichuan-Tibet Highway." Tongmai Tianxian insurance is 14 kilometers long, located between Bomi and Bayi. Known as "Tongmai Cemetery", it was once the most dangerous section of the Sichuan-Tibet Line <>318 National Road. The soil of the mountains along the line is relatively loose, and there are snow-capped mountains and rivers nearby. When wind and rain or ice melt, mudslides and landslides are easy to occur. It is known as the "world's second largest mudslide group". Therefore, Tongmai and Pailong have the "death section" on the front line. The Palon 10 kilometers in front of Tongmai Town is even more known on the Sichuan-Tibet line. The famous Tianxian. Now the "five tunnels and two bridges" of the Sichuan-Tibet Highway Tongmai section is officially opened to traffic, the Sichuan-Tibet Highway once "Tongmai Tianxian" has become gorgeous history. First generation: Yigongte landslide in April 2000, Yigong Lake burst dam, the original reinforced cement-filled bridge was engulfed by floods, and traffic on the Sichuan-Tibet South Line was completely interrupted. In June of that year, the local transportation department built a bridge, which is the first generation of existing bridges. Second generation: built in December 2000, this is a temporary two-tower double suspension bridge, due to safety considerations, the weight limit of 20 tons, so the traffic queues waiting to cross the bridge is very common. The bridge suffered serious failure in 2013 and 2015, which caused traffic disruption on the Sichuan-Tibet South Line. Third generation: single tower single-span steel truss suspension bridge, bridge length 256 meters, door cable tower, tower height 59.5 meters. TIPS from Nyingchi Bayi City to Bomi is said to have a regular operation shuttle bus, but I can't buy tickets at the ticket counter of the passenger terminal. It is said that I only bought one of the Iveco in the passenger terminal square. I walked around and couldn't find it. I could only give up. I also tried to take a black car (100 yuan/person), but because I can only make up for the full talent to leave, I can't stand it after more than an hour. I decisively took a Didi ride, and the cost was more than ten yuan. It only takes 4 hours (because of the speed limit) to be sent to the inn in Bomi.

Walking 318 to #Tongmat Bridge# This is a must stop, anyway, punch a card, formerly called #Tongmai Tianxian#, here can be said to be witness, three generations of bridge, lamenting that China really spent a lot of money on infrastructure, worthy of infrastructure mad demon, finally repaired here is no longer a Tianxian, The place where ordinary vehicles can pass, it is worth taking pictures~ There are really many places on this road with the sign of 318 must-check in~

I have to praise these army of road and bridge construction. Now the new Tongmai Bridge is open to traffic, which is beautiful and safe.
