Why are there so many overpasses on the highway?

A highway is a highway that allows cars to separate lanes and drive at high speeds and control all access to highways. Generally able to accommodate speeds of 120 km/h or more.

In order to ensure the high-speed and safe driving of high-speed vehicles without interference, three-dimensional crossing, pedestrian cross-line bridges or tunnels are used with other lines to avoid mutual waiting (such as intersection traffic lights) and plane crossing interference caused by plane crossing. The expressway not only has many overpasses, but also has more road crossings that cross up and down.

In addition, expressways require smooth routes, gentle slopes, and road widths of more than 4 lanes. A dividing belt is set in the middle to divide the vehicle into different directions. The pavement is made of asphalt concrete or cement concrete high-grade pavement, and there are complete signs, markings, signals and lighting devices to ensure driving safety; Install isolation and protection facilities on the outside to avoid animals and pedestrians; Pedestrians and non-motorized vehicles are not allowed to walk on the road.

In short, it is to ensure that the vehicle drives at high speed and safely.

There are many overpasses built on the highway:

The first is to allow the car to drive at high speed on the road unimpeded;

second, in order to play the role of adjusting highways;

This is because there are also signs and communication facilities on the road, which prohibit pedestrians and non-motorized vehicles.

The main thing is to let everyone drive safely.

The main differences are, different properties, different main functions, and different main features, as follows:

First, the nature is different.

1. Viaduct.

Generally refers to bridges that cross deep ravines and canyons in place of high embankments, as well as bridges that cross roads in urban bridges, supported by towers or pillars with high support.

2. Overpass.

The full name is "three-dimensional orange year excavation cross bridge", which refers to the modern bridge established at the intersection of more than two intersecting roads, including the sunken tunnel in the three-dimensional crossing project (because the bridge structure will be formed above the main body of the tunnel).

Second, the main functions are different.

1. Viaduct.

Towers or pillars with high supports, bridges that cross valleys, rivers, roads, or other low-level obstacles. After the development of the city, the traffic is congested, the buildings are dense, and the streets are difficult to widen, the use of this kind of bridge can evacuate the traffic density and improve the transportation efficiency. In addition, in the inter-city highway or railway, in order to avoid horizontal intersection with other lines, save land, and reduce subsidence of the roadbed (in some areas), this kind of bridge can also be used instead of embankment.

2. Bird's Eye Overpass.

Avoid multi-directional vehicles intersecting at interchanges. The main function is to enable vehicles in all directions to pass quickly without being controlled by traffic lights on the intersection.

Third, the main features are different.

1. Viaduct.

The height of the pier is high, and the reinforced concrete row frame or single-column and double-column reinforced concrete piers are generally used.

2. Overpass.

The road plane is separated or the three-dimensional circle core crosses to form multiple layers.

Hello, it is my pleasure to serve you and give you the following answer: An interconnected bridge is a connection between two or more bridges, which can be on the same river or on different rivers, and they can be connected to each other so that traffic and pedestrians can move freely between different bridges. An overpass is a bridge built at the intersection of two or more roads, and they allow pedestrians and vehicles to move freely between different roads without the need to bypass the intersection.

The difference between an interchange bridge and an overpass is that an interchange bridge is a connection between two or more bridges, whereas an overpass is a bridge built at the intersection of two or more roads. For example, the causes of problems with silver: 1

Unqualified construction quality: Due to unqualified construction quality, the structure of the bridge may be unstable and prone to damage, which will affect traffic safety. 2.

Poor maintenance: Due to poor maintenance, the structure of the bridge may be damaged, which will affect traffic safety. 3.

Climate change: Due to climate change, the structure of bridges may be damaged, affecting traffic safety. Workaround and Procedure Steps:

1.Strengthen the quality of construction: When building bridges, quality control should be strengthened to ensure the structural stability of bridges to ensure traffic safety.

2.Strengthen maintenance: The bridge should be maintained regularly, and the damage to the bridge should be found in time and repaired in time to ensure traffic safety.

3.Strengthen protection: Effective protective measures should be taken to prevent the impact of climate change on bridges to ensure traffic safety.

Personal Tips:1When building bridges, quality control should be strengthened to ensure the structural stability of the bridges to ensure traffic safety.

2.The bridge should be maintained regularly, and the damage to the bridge should be found in time and repaired in time to ensure traffic safety. 3.

Effective protective measures should be taken to prevent the impact of climate change on bridges to ensure traffic safety.

Interchanges (highway interchanges or overpasses) are called "three-dimensional cross-line bridges", which refer to modern bridges built at important traffic intersections in the city, layered up and down, multi-directional traffic, and do not interfere with each other. Due to the high cost of construction, it is usually only built at the intersection of highways, urban arterial roads, or expressways. Its main function is to enable vehicles in all directions to pass quickly, not affected by the traffic lights at the intersection.

It is the inevitable product of human transportation modernization and urbanization of residential areas, one of the urban public infrastructure, and an indispensable part of the efficient transportation system of contemporary society. The most important function of the overpass is to use the method of air isolation to eliminate the conflict of cross traffic on the road plane, alleviate congestion, save driving time, and enhance driving safety. To a certain extent, divert the traffic flow in the direction of the main road or even the branch road, so that the straight traffic of the two intersections is unimpeded; In addition, it can reduce or eliminate the mixing probability of motorized vehicles, non-motorized vehicles and pedestrians, and improve the overall safety factor of the road.

The difference between a standing standard and a large standard.

The difference between the station logo and the big mark is that the Mercedes-Benz brand is defaulted here. Strictly speaking, there is no difference between a standing bid and a large bid. If you insist, it seems that the bid is more luxurious; The big logo is more sporty and fashionable.

In fact, to put it bluntly, the manufacturer intends to make the front grille of the car more beautiful with the big logo or vertical logo.

And the owner can change it himself if he wants to. Online bidding is less than 100 yuan, while 4S stores may cost more than 500 yuan. If there is no hole in the hood where you can insert a logo, then buy a logo that you don't need to plug in and stick it on the hood.

A brief summary of the history of large-scale bidding: the earliest Mercedes-Benz was a tender. And in foreign countries, only the standard Mercedes is the most authentic Mercedes pedigree.

However, since the promotion of the C-class in China, the overall sales of the C-class have been immediately improved, so the new models in the later period are all using the big standard, but the standard is still retained.

Mercedes-Benz Profile:

Mercedes-Benz, a century-old German car brand, the pioneer and leader of automobile civilization, is considered one of the most successful high-end car brands. The Mercedes-Benz Trident Star has become one of the most famous car and brand icons in the world.
