An __________ is the connection of an expressway to a road or another expressway by a series of ramps.

Explanation

An interchange is a road junction where two or more roads cross over one another so as not to impede one another's traffic flow. Instead, the roads are connected through a series of connecting ramps. These ramps allow you to leave one road and enter another one safely, without disrupting the flow of traffic. There are cloverleaf, diamond, and divergent (diverging) diamond interchanges, among others.
