"The bridge in the middle looks quite strong, how can it be broken?And, Qingqing, what is the car Baotong Bridge?" the other girl asked puzzled, Chu Qian was also very curious, wanting to know the answer.

"The car Baotong bridge in the middle is indeed quite strong, but this bridge is only a temporary car Baotong bridge at all. Well, the car bridge refers to a kind of bridge that ensures that cars can pass, and this kind of bridge is usually temporary. ”

"Then why not build a permanent bridge? like the Tonmai Bridge. Chu Qian asked.

"I heard my dad say that there used to be a permanent bridge here, which was built when the Sichuan-Tibet Highway was built, and it was a reinforced concrete bridge. However, in the 2,000 years of Yigong Zangbo upstream of Yigong Township there was a landslide, the collapsed mountain blocked the upstream Yigong Lake, forming a dammed lake, as a result of the Yigong Lake dam failure, the water mixed with a large amount of mud and rocks along the Yigong Zangbo River rushed down, directly the bridge was washed away. I heard my dad say that the impact of the dam failure was very great, not only did it wash away the bridge here, but the excess water poured down the Palung Zangbo River into the Yajiang River, and finally destroyed the Jiefang Bridge in Beibang Township, Medog County, 180 kilometers away......

Chu Qian was a little messy, "Sister Qing, you asked me to sort it out, you said that the dam burst actually washed away the liberation bridge in Motuo's back collapse township?

It's no wonder that Chu Qian doesn't believe it, it's really too far away from here, nearly two hundred kilometers. Moreover, how could a dam failure in the upper reaches of the Yigong Zangbo River affect the Beibang Township in the lower reaches of the Yajiang River? Do you really think that the wide channel of the Yajiang River is an ornament?

In order to see Nanga Bhava Peak in the summer, Chu Qian had a very detailed understanding of the surrounding situation, and even learned about the hiking route of Motuo, so she naturally knew where Beiban Township was.

That township borders Asan in the south, and it belongs to the border.

Zhao Qing shrugged his shoulders and said, "Don't ask me about this, I don't know." I was five years old when it happened, and I listened to my dad. But I think it's true, because my dad was still here with a team......

Chu Qian and the other girl couldn't refute it.

Zhao Qing continued: "My dad said that the time when the bridge was washed away was in early April, and in order to ensure that the Sichuan-Tibet Highway was restored to traffic as soon as possible, it took them more than a month to build a temporary suspension bridge, which was the smallest suspension bridge. The suspension bridge was built for the construction of the Auto Baotong Bridge to transport materials. After having this suspension bridge, my dad and they started to build the car bridge again, and it took them seven months to build the middle car bridge, which was repaired in December in the 2000th year. In other words, the dam failure that occurred in 2,000 years directly caused the Sichuan-Tibet Highway to be interrupted for eight months!

My dad said, "This temporary car bridge only has a load of 20 tons, so you can only pass one car at a time." If the truck exceeds this weight, it must first unload a part of the cargo. My dad led a team to stay here for more than half a year after the bridge was repaired. He said that the daily work of his soldiers at that time was three things: daily inspections, restricting the passage of overloaded vehicles, and clearing the traffic jams on the road. ”

Chu Qian and the other girl were silent.

Although they had not seen those lovely and respectable soldiers with their own eyes, they could fully imagine what kind of danger these soldiers had taken to build the bridge here, and how hard they worked every day to ensure the safety of the bridge.

Although these loveliest people did not go to the battlefield to defend their families and defend the country, they used their silent efforts to ensure the smooth flow of the main artery of the Sichuan-Tibet Highway, and they are also heroes!

None of the three girls noticed that the three male companions who had finished smoking had quietly come up.

Liu Moang, the three of them also heard what Zhao Qing said just now, and they were all silent.

After a long while, Lao Liu asked, "Has the Baotong Bridge for cars also been broken?"

Zhao Qing nodded, "On August 2, 2013, the night was broken, and the next morning, my father and my mother and I were blocked here, and it took three days to return to Bayi." Because we didn't know that the car Baotong Bridge was broken, there was no way back when we walked here. At that time, the 14-kilometer road of Tongmai and Pailong was not built without a tunnel and the Qilonggou Bridge, and the road was very difficult to walk, and it was fast to walk this section in two hours. ”

Lao Liu nodded silently, and he remembered what he had heard from Li Junyi about this place before.

At that time, Tongmai was known as the "encyclopedia of the world's highway diseases". There are still many people who say: "If you haven't walked through Tongmai, you don't know the difficulty of the Sichuan-Tibet line." ”

These words can directly prove how difficult the road to Tongmai is to walk.

Chu Qian asked in surprise, "Your family of three has been blocked for three days, did you spend it in the car?"

Zhao Qing shook his head and said, "No, one of my father's soldiers stayed here back then? When we were blocked that year? That uncle was already the captain of the fourth brigade of the third traffic detachment of a certain unit of the army? They were guarding here at Tongmai Bridge." My dad looked for him, and our family of three crossed the river from the suspension bridge and stayed in the barracks at the Tongmai military station for three days. My dad went out every day to help clear the vehicle, and he came back every day with muddy water.

When I was staying in the barracks, I heard from the soldiers that it was almost 12 o'clock that night when a truck happened to cross the bridge, driven by two Tibetan compatriots. As a result, when the car was walking on the bridge, the rivets on the bridge fell off, causing part of the bridge deck to collapse. The car, along with two Tibetan compatriots, fell into the river below and could not be saved. Two other hikers who were also on the bridge at the time were also missing. ”

The crowd was silent again.

If you don't listen to it, you don't know it, but this listener really feels the danger of Tongmai Tianwei.

No wonder it is known as China's No. 1 automobile cemetery.

Although the car Baotong Bridge was repaired later, the state still invested heavily in the transformation of Tongmai Tianbao. In the most dangerous Pailong Laohuzui and here, the Qilonggou Bridge and the Tongmaite Bridge were built, and the Palong No. 1 and No. 2 Tunnels, Xiaohuzui Tunnels, Feishiya Tunnels and Tunnel 102 were also built. Well, after you cross the Tongmai Bridge and walk about 10 kilometers forward, you will see Tunnel 102. At that time, the situation there was even worse than here, which was the third in the world, the first in Asia, and the most difficult to rectify in Asia. What's even more terrifying is that there used to be cars smashed by collapsed mountains, and that section of the road is known as the death section of the Sichuan-Tibet Highway!

But now, after the 102 tunnel was built, there has never been a case of a vehicle being smashed there, and there has never been a road break. You can keep an eye out for a moment when you walk there, and on the south side of the tunnel entrance you can still see the old Sichuan-Tibet Highway. When you see that road, you know how difficult it was back then. ”

......

"It's better to read 10,000 books than to travel 10,000 miles, and that's true. This time it's really a long experience!" In the co-pilot's seat, Chu Qian said with some excitement while eating a pack of shrimp crackers.

"Yes, if we hadn't met Zhao Qing and them, we wouldn't have known that so many things had happened here back then. However, after listening to these things that Zhao Qing said, I felt a little uncomfortable, I didn't expect that Tongmai Tianbao would be like this back then. No wonder Zhao Qing and they want to remember Tongmai Tianwei here. ”

Chu Qian smiled: "If I experienced so much on this highway when I was a child, I will definitely remember it now." ”

Laughing, the car drove across the Tongmaite Bridge, walked forward for a short time, and saw the monument to the ten heroes on the Sichuan-Tibet line on the side of the road.

After seeing this monument, Lao Liu took the initiative to drive the car over and park it in the parking lot, and then went over to remember the ten heroes who died when they encountered a huge landslide when they were carrying out the logistics support and transportation mission.

These heroes are the most memorable, and what they did is worthy of the title of "heroes"!

The monument is in the west of Tongmai Town, not far from the east is the Tongmai Military Station, for decades, the soldiers stationed here have changed one after another, and the soldiers who have fought here do not know how many people, they use their efforts and struggles to silently protect the smooth flow of the Sichuan-Tibet Highway.

They may be unknown, but there is no doubt that they are no less heroes!

After about 10 kilometers of eastward travel, the car passed through the town of Tongmai and saw a tunnel. To the north of the entrance to the tunnel, a barely visible path branched off the Sichuan-Tibet Highway and headed up the mountain.

Obviously, this road is the old Sichuan-Tibet Highway that Zhao Qing said before.

Just looking at the width of this road, Lao Liu and Chu Qian both felt a little shocked.

If it weren't for Zhao Qing's special words before, neither Lao Liu nor Chu Qian would have thought that this road hidden in the jungle was actually the old Sichuan-Tibet Highway.

"Sister Qing said before that the road conditions on the 102 class were not much worse than those of Tongmai Tianha, I didn't believe it at first, but now I believe it after looking at this road. Chu Qian looked at the road next to the milestone with a worried expression on her face.

"Yes, this road was only one-way traffic back then, there were special personnel at both ends of the road holding walkie-talkies to communicate, and passing vehicles lined up at both ends. I can't even imagine how to go on that road......" Lao Liu is also a little toothy.

The contrast between the two paths is too stark. On this side is a new, smooth two-lane asphalt road, and on the other side, it is not much stronger than a country dirt road......

After getting on the bus, pass through the 1,731-meter-long Tunnel 102 and continue east along the Sichuan-Tibet Highway that runs through the Palung Zangbo Valley.

When passing through Guxiang Lake along the way, I got out of the car and stayed for about 15 minutes to take pictures and videos.

The white lion is also loved by the local Tibetan compatriots here, and a Tibetan mastiff with a clear blue color even keeps coming to the white lion's side. As a result, the concubine was ruthless, and the white lion was stunned and ignored the female dog. was in a hurry, the white lion still wanted to bite people, and was driven back to the car by Lao Liu with his ass.

However, before leaving, an elderly Tibetan in the local area also gave Lao Liu some fresh offal, and pointed out that it was for the white lion to eat.

Because of the language barrier, it was the old man's child who made the translation, and Lao Liu figured out the old man's mind.

This time, Lao Liu learned well, and he brought Hada in the car, so Lao Liu gave the old man and his children a Hada, and the old man said that he would also leave Lao Liu and Chu Qian for lunch.

The two eventually fled in a hurry......

Because they had stayed in Tongmai Tianbao for a long time, when they entered Bomi, it was almost twelve o'clock in the afternoon.

The morning meal was early, and the two of them were already hungry by this time. So I found a small restaurant where I could bring my dog in. The white lion's food is naturally the cow offal sent by the enthusiastic old Tibetan compatriot.

After eating, Lao Liu planned to rest in the car for half an hour. It is very exhausting for a person to drive on the road conditions of National Highway 318 for a long time, and even Lao Liu can't stand it anymore.

Chu Qian found a supermarket to hang out by herself, of course, it is estimated that her biggest purpose is to buy some snacks.

Lao Liu squinted in the car for half an hour, in good spirits, and the two continued to drive all the way up.

In fact, since passing Tongmai, this road is basically climbing a mountain. The altitude of Tongmai is only about 2,000 meters, but when you reach Bomi, the altitude has reached 2,007, and when you arrive at Ranwu two and a half hours later, the altitude has reached 3,960.

There is a very famous alpine dammed lake in Ranwu, which is known as the most beautiful lake on the Sichuan-Tibet line.

Just as Cuona Lake is the source lake of the Nu River, the largest lake in eastern Tibet is also the source lake of the Palung Zangbo River.

However, this lake is nothing to the young couple who have seen the Namco and the wrong lake.

After staying at Ranwu Lake for about half an hour, the little couple continued their journey. Today's destination is Hachijuku, 90 kilometers away.

After walking a short distance from Ranwu, I saw snow on the side of the road. Lao Liu put snow chains on the car, and the car continued to climb up, because it was about to cross the pass of Anjura Mountain at an altitude of 4,475 meters.

Unlike the passes of many famous mountains and rivers, which are generally steep and undulating, the Anjura Pass is surprisingly gentle. It's a bit like the Tojula Pass and Tanggula Pass that Lao Liu walked through when he drove home from the Qinghai-Tibet Line in August. Before I knew it, I had reached the pass of Anjura Mountain, which was full of wind and horse flags.

However, it is the inconspicuous pass of the Anjura Mountain, which belongs to the Peshula Mountains, but it is the watershed of the Nu River and the Brahmaputra River. After crossing the pass, it is from the Brahmaputra River basin, where legends and myths have grown, into the Nu River basin!

There is a huge blue sign on the Anjura Pass, which reads "Anjura Mountain, 4475 meters above sea level", and there are four slogans under this line - not afraid of hardships and dangers, not afraid of bloodshed and sacrifice, Baotong Sichuan Tibetan moat, forging rescue pioneers.

The final payment was the second traffic detachment of the armed police.

When you see a sign like this, you will be in awe!

The 4,475-meter Anjura Pass is already covered with snow. At this time, the mountain passes with an altitude of more than 4,000 are basically covered in snow.

After crossing the Anjura Mountains, the car began to go downhill. I found a wide place to remove the snow chains halfway through, and by the time we arrived at Yajukude, the sun had already begun to sink in the west.

Although the total mileage from Lulang Town to Basu on this day was less than 400 kilometers, there was a lot of delay on the way, so the road took nearly 12 hours.

The county seat of Basu is very small, and even Lao Liu feels that it is not as big as the town of Ranwu that he passed by before.

The two booked two rooms in a hotel on the way. There are no star-rated hotels here, let alone suites, so you can only book two single rooms.
