Explain with the help of sketches, the following types of interchanges:

a) Diamond interchange

b) Clover leaf interchange

c) Trumpet interchange

Interchange:

It is a system where traffic between two or more roadways flows at different levels in the grade separated junction.

The main types of interchanges are;

a) Diamond interchange

b) Clover leaf interchange

c) Trumpet interchange

Step-by-step explanation

Trumpet interchange:

• It is a form of three leg interchange.
• In this type of interchange, one of the legs of the interchange meets a highway at some angle but does not cross it.

• Diamond Interchange:

• It is popular form of four-leg interchange.
• It is basically found in the urban locations where major and minor roads crosses.
• The important feature of this interchange is that it can be designed even if the major road is relatively narrow.

  Clover leaf interchange:

• It is a four legged interchange.
• It is used when the two highways of high volume and speed interest each other with considerable turning movements.
• The main advantage of this type of interchange is that it provides complete separation of traffic. In addition, high speed at intersections can be achieved.
• The disadvantage is that a large area of land is required. Therefore it is mainly provided in rural areas.
