What are the four types of interstate interchanges?

There are four correct answers to this question, which are:

A. Cloverleaf- eliminates left turn and cross-traffic. With this interchange, ramp roads handle the left turns. It is an interchange, which as two levels.

B. Diamond-little traffic crosses a busy expressway. This interchange is very common, and it occurs when a freeway crosses a minor road.

C. Trumpet- side road forms at the intersection with an expressway. This occurs when one highway ends at another one.

D. Directional-complicated intersections with a high volume of traffic, diff directions. This has connected, which are directed at the major turning movements. Those directions usually are 90 degrees.

Directional T interchanges use fly/over/underpass ramps for both connecting and mainline segments. They require an average amount of land and costs. Cloverleaf interchange is typically a two-level, four-way interchange where all turns across opposing non-directional loop ramps handle traffic.

The diamond interchange is economical in use of materials and land than other interchange designs. Basketweave interchange is commonly found on highways using a collector/express system of running collector-distributor lanes. Trumpet interchanges are used where one highway terminates at another highway.
