What is Interchange (road)?
[[File:Florida SR 408 at SR 435.jpg|thumb|Diamond style]] [[File:Klaverblad unknown location .jpg|thumb|Cloverleaf style]] An '''interchange''' is a place where two [[freeway]]s meet, or where a freeway and another [[road]] meet. An interchange has two levels so traffic going through does not meet. Different levels are connected by ramps. There are many different types of freeway interchanges. The two most common types of freeway interchanges are the diamond interchange and the cloverleaf interchange: * A diamond interchange has four [[inclined plane|ramps]] that enter and leave the freeway at a small angle and meet the non-freeway at almost right angles. These ramps at the non-freeway can be controlled through stop signs or [[Traffic light|traffic signal]]s. The name comes from the diamond-like shape. * A cloverleaf interchange has eight ramps that handle all traffic without stop signs or traffic lights. To turn left, traffic goes in a 270° turn. The name comes from the four-leaf [[clover]]-like shape. [[Category:Roads]] [[Category:Bridge types]] {{transport-stub}}
