The yellow line in the middle of the road is naturally the dividing line. It is designed to avoid head-on collisions of vehicles that are approaching each other. It is said that after the yellow line in the middle of the road, the traffic accident rate has decreased a lot and quickly It is popularized on a large scale.

Although the vehicles of the Great Tang are all carriages, the driving speed is relatively low, and the probability of head-on collision is relatively low, but the road regulation work still needs to be done in advance. After all, the steam freight car has been put into use. In the future, Steam passenger vehicles will also appear, so the speed must be faster than the carriage, and a collision is a major accident.

In addition, when there is no middle line rule, dignitaries often fill the entire road surface, and oncoming vehicles and pedestrians must retreat to the side of the road, or even into the fields beside the road, Caused great damage, this situation must be stopped.

“Your Majesty, the yellow line in the middle of this road is the pedestrian separation line. Pedestrians and vehicles going out of the city go to the right of the yellow line, and pedestrians and horses entering the city go to the left. The accident can also avoid the dignitaries fighting with the 100 surnames, reflecting the love of the people of Imperial Court. “

Li An explained.

“Well, the yellow line for Minister Li is well set up. In this way, it can reduce the occurrence of disputes over the Taoism. According to my will, in the future, officials and nobles should not fight against the 100 surnames. Everyone must travel on the right. , As long as the road is wide enough, it must not exceed the center line. “

Li Longji spoke the imperial edict, and the ministers quickly responded.

The rules of the middle line and the right-hand line can only be implemented very well in the vicinity of the metropolis. After all, in many remote areas, the road can only barely accommodate a carriage. If you drive on the right, the carriage will be difficult to walk Of course, this is another situation, and with the gradual popularization of cement and concrete, in the future, many major roads in Great Tang will be paved with concrete pavement, and as long as the road above the county level, there must be 3 cars The width above meets 2 carriages facing each other.

The concrete pavement is very strong. With the current carriage and pedestrian horses of Great Tang, even if you walk on it day and night, it will not cause any harm to the concrete pavement. Such a hard pavement can be maintained for hundreds of years without damage. Small cracks and sinking bumps can be repaired quickly.

With the subsequent steam freight vehicles driving onto the road, the damage to the road may be greater, but the manufacturing capacity of Great Tang is very limited. A small number of freight vehicles will not cause too much damage to the concrete road. Moreover, as long as When the time is ripe, Li An will invent tires, and the development of tires requires rubber materials, that is, plants native to South America. Traveling to South America and bringing back the Rubber Tree seedlings will take many years. That is to say, if It will take many years to invent rubber, and for the time being, only iron wheels will be used.

After taking a few hundred steps, Li Longji and the ministers boarded a wide concrete bridge.

This bridge incorporates a lot of steel materials to serve as a skeleton. It is far stronger than ordinary stone bridges, and it is also designed to be more atmospheric and luxurious. In addition to the necessary stripes to prevent thermal expansion and contraction, the bridge deck has also carved a lot of Dragon Phoenix The pattern looks quite spectacular, most of which are in the middle and can be used to separate pedestrians.

On the 2nd side of the bridge is a concrete guardrail. The side of the guardrail is also carved with a considerable number of various patterns. On each stigma at the top of the guardrail, a lion and various Divine Beasts are also carved, which looks very domineering.

Of course, what surprised Li Longji and the ministers most is that such a large-scale concrete bridge was built in half a month, and neither the quality nor the scale was said.

“This concrete bridge is much faster than the stone bridge before it was completed in half a month.”

“The construction is completed so quickly, will there be any problem with the quality!”

Several ministers talked to each other, and Li Longji looked towards Li An, instructing Li An to introduce the specific situation of the bridge.

“Your Majesty, the concrete bridge not only has a fast construction speed, saves costs and manpower, but is also much stronger than a stone bridge, can bear greater weight without collapse, and is very suitable for replacing the stone bridge. In addition, with this technology After that, bridges can be erected on the Yellow River and the Yangtze River, so that the sky will become smooth, and in the future, the railroad tracks can be directly paved to all the states of Great Tang. “

Li An spoke introduced.

“Minister Li actually wants to build bridges on the Yellow River and Yangtze River, how is this possible.”

“The Yellow River and Yangtze River are as wide as several li, even a dozen or more li.”

“The Yellow River is surging, how can the bridge stand on it.”

The ministers were shocked, they all felt that Li An was crazy, even though concrete bridges are stronger than stone bridges, but they cannot be arrogant to think that bridges can be erected on the top of the Yellow River and Yangtze River, which is too difficult. .

Li Longji is also a facial expression grave, looked towards Li An: “Minister Li, you really think that you can build bridges over rivers, how much do you have confidence?”

“Your Majesty, as long as you have enough manpower, materials, and technology accumulation, it is entirely possible to build bridges on the Yangtze River and the Yellow River. However, it takes a lot of time to accumulate technology and material preparation. If you want to build a bridge on the Yellow River and the Yangtze River, at least 3 -5 years later! This Small Official feels that it is possible to build concrete bridges on not too wide rivers such as Luoshui, Grand Canal, and Jishui to accumulate technology, and at the same time facilitate the subsequent laying of rails east of Mount Tai In Laizhou and Mizhou, your Majesty will arrive in Mount Tai within a few days. “

Li An opened the introduction, and stated the next step of the rail laying plan, that is, starting from Luoyang City, laying eastward, after crossing a large number of Water Element, arrived at the junction of Mizhou and Laizhou.

There is a large bay, which is very suitable for a seaport, that is, the Jiaozhou Bay in later generations, and Li An chose to lay the rails to the Jiaozhou Bay. Next step is marine strategic services.

“It turns out that Minister Li’s next step is to lay the rails towards Mizhou and Laizhou. It would be great if it could be repaired.”

“Whether the rails can be smoothly paved to Mizhou and Laizhou depends on whether the bridges along the way can be successfully built.”

“Yeah! If you can’t build these bridges across the canals, the rails will be difficult to pave to the east.”

“I’m afraid it’s not easy! Although the Luo River and the Grand Canal are not as wide as the rivers, they are not too narrow! If you want to build a bridge on it, I am afraid it is not easy.

“I think it is feasible. Since Minister Li is determined, these bridges should be able to be built.”

“Even if the bridge can be built, how to ensure the passage of ships, especially the Grand Canal, is the top priority of the water transportation. If the bridge blocks the boat, the water transportation will be abandoned.

“Eh, since Minister Li has proposed to build these bridges, I must have taken this into consideration long ago, and it will certainly not affect the transportation.”

“Yes, yes, Minister Li did not let me wait and start this time, this time, I will be able to lay all these bridges successfully.”

All the ministers heard that Li An was going to build a large number of bridges along the way, and they thought they would lay rails in the future.

“Minister Li, these rivers along the way are not so narrow, how sure are you?”

Asked Li Longji facial expression grave.

In addition to the 2 River Water Element, Luoshui, the Grand Canal, and Jishui are not narrow, especially Jishui. The width of the downstream is nearly 2 miles. It is inevitable that it is not easy to build a bridge on it. At least, Li Longji does not want to. Dare to think, shocked and puzzled by Li An’s plan.

“Your Majesty, This Small Official has complete assurance, you can definitely repair these bridges, first build the narrowest bridge to gain experience, and finally build the Jishui Bridge, and the Huaihe River in the south of the Yangtze River, and the bridge will also be built in the future.”

Li An answered confidently.

Of course, Li An can say this remark so confidently, it has the strength to support it, concrete and steel have come out, and there are various basic machinery. As long as you spend time researching and training a bridge-building team, it is not a problem. of.

“Since Minister Li is so confident, I also hope that these rivers will be able to build bridges, but it must not interfere with water transport, which must be guaranteed.”

Li Longji still supports these major projects. After all, these projects can benefit 1000 autumns and 10000 generations, and Great Tang currently has such a national power, of course, to be built.

“Yes, Your Majesty, This Small Official will form a team dedicated to building bridges, and all big bridges in Great Tang will rely on this team in the future.”

Li An is happy to accept the task and is ready to form such a bridge-building team immediately after going back.

After crossing the concrete bridge, on the left side of the road is a large-scale pavilion. This pavilion is larger than other pavilions. There are dozens of concrete stone benches in it, which can accommodate more people to rest together to avoid rain. Is more appropriate.

On the right side of the road, there are two-story concrete buildings, which are no problem for living.

Li Longji and the ministers first made a round in the pavilion, asked about the cost, and then went to the 2-Layer building, and climbed onto the small platform on the 2nd floor, overlooking the scenery around all around.

“Your Majesty, this concrete pavilion and house is much stronger than wood. The sword can only hurt its hair, and cannot move its root. The ultimate thing is that the concrete cannot be burned, and there is no need to worry about being destroyed by the fire.”

Li An introduced the advantages of concrete buildings.

“A house that is not afraid of fire, not bad, very good.”

Li Longji was very satisfied with the concrete structure of the house, paused, and asked, “How many layers can be covered by such concrete prevention?”

“Back to Your Majesty, as long as the financial resources, labor and materials are sufficient, there is no pressure to build a 100-story building, and it is sturdy and abnormal and will never collapse.”

Li An had no choice but to answer.

“It’s possible to build 100 floors with 100 floors. How is this possible.”

“The treasure tower in the temple is not more than a dozen floors, how to build these 100 floors?”

“Minister Li said, if you can build 100 floors, then you will be able to build so high, I believe Minister Li.”

“I really want to see what a 100-story house looks like!”

The ministers whispered that they did not dare to think about the 100-story building. After all, it was too high, beyond their knowledge of the building.

“Minister Li, can you really build a 100-story house?”

Li Longji’s expression was extremely shocked. There was a trace of excitement in the surprise. If you can really build such a high house, wouldn’t it be standing on the upper floors and you can see the scenery of the whole capital, how cool should that feel! Moreover, a 100-fold telescope has now been developed. As long as there is a commanding height, the whole city can be taken in the entire scene, and even what the 100 surnames in each city are doing can be seen clearly.

“Your Majesty, This Small Official dare not to joke, as long as all the materials are sufficient, you can definitely build a 100-storey house, but building a 100-storey house does not make much sense, and it consumes too much material and manpower.”

Li An gave an affirmative answer, and at the same time, pointed out that building a house that is too high has no practical meaning, so Li Longji should not be overheated.

“It’s not necessary to have 100 floors, but building a 20th-layer house is a try. The Taishi Bureau observes the nebula and needs a higher position. I will let Minister Li build it later.”

Li Longji has n’t figured out where to build the 20th-layer building. After all, such a high-rise building is too conspicuous, and he is an Emperor of a country. He needs to consider various aspects in a comprehensive way. For example, build such a high-rise building and put it in Where can we embody the prestige of the Great Tang Empire, how to avoid being used to observe the Imperial Palace, how to facilitate the climb to the top of the building, and observe the scenery of the capital, these must be considered. Who made him the Emperor?

After affirming the great role of cement and concrete, Li Longji and all the ministers agreed that cement production workshops should be built throughout the Great Tang, and the counties should organize manpower during the agricultural slack to build important roads in the country. The roads at the county level of Great Tang can be concreted to facilitate the travel of 100 people and promote economic development.

To promote cement workshops, it is necessary to train talents in cement manufacturing first, and then let them go to various states and counties to build cement workshops, and gradually mobilize manpower to build main roads in the country.

Because there are too many states and counties in Great Tang, there are more than 300 formal states, and the county-level units are more than 1000. The training of such a scale of talent is too exhausting. For this reason, Li An decided to train a small number of talents first. After letting them learn, they went to various construction cement workshops and recruited a large number of personnel for training. Then, some of the talents were drawn out and organized into cement workshops in each state. Most of Tang’s counties and counties popularize cement manufacturing workshops.

Of course, this is only a very ideal state. In the actual operation process, all states and counties must not be allowed to build cement workshops. After all, some states have no raw materials, so of course, it is not suitable for building cement workshops.
