A turnpike is a road or highway on which drivers may travel for a fee. On a turnpike, an authority collects a toll from drivers as they enter the road, exit it, or while they’re traveling on it. Turnpikes, or toll roads, exist around the world. In the United States, they are most heavily concentrated in the eastern portion of the country. Toll amounts vary with each turnpike; in some places, tolls vary according to vehicle class as well.
也就说：Turnpike是针对司机收费的普通或高速路。司机在进出turnpike时，需向公路管理方交费（toll）。Turnpikes，也被称为toll roads，在全球非常普遍。在美国，Turnpike主要集中在东部地区。各条收费路的费用标准不尽相同，并会针对车辆的类型进行收费。
我们来看个关于turnpike的例句：
The Pennsylvania Turnpike Commission (PTC) has approved toll rates for a cashless, nonstop tolling point for westbound motorists crossing the Delaware River Bridge from New Jersey into Pennsylvania on Interstate 276.
参考译文：宾夕法尼亚州收费路委员会（PTC）批准了一个不停车电子收费点的收费标准。该站收费对象为：经由州际公路276从新泽西州进入宾夕法尼亚州，并西向穿越特拉华河大桥的车辆。
