A freeway entrance, also known (at least in the US) as an onramp, is the road that provides a transition from surface street to superhighway. Freeway entrances tend to be one-lane, one-way roads, and often take a circular, gently banked path as they deposit vehicles into a whizzing blur of traffic.
