“收费公路”英语怎么说

摘要：全国收费公路专项清理第一阶段摸底调查已于8月底结束，按照要求，各地摸底情况近期将对外公布。截至昨日，至少已有北京、上海、山东等12省份公布了收费公路摸底调查结果。你知道怎么用英语表达吗?

Traffic authorities in the capital said on Saturday the city's toll roads are still in heavy debt, as one-third of the tolls collected from highways were paid as interest to creditors who financed construction of the roads.

Beijing Municipal Commission of Transport, the city's traffic watchdog, said on its website that at the end of 2010 there were 816 km of toll roads in the city, with unpaid loans worth as much as 44 billion yuan ($7 billion).

周六，北京交通委称北京收费公路仍然负债严重，高速公路收费的三分之一都用来偿还建设公路的贷款利息。北京交通监管机构—北京市交通委在其网站上称，截止2010年底，全市共有收费公路816公里，债务余额高达440亿元。

　【讲解】文中的toll roads即指收费公路，toll在这里指通行费，toll作名词时还有伤亡人数(death toll)和钟声的意思，toll还可以作动词，有敲钟(For Whom The Bell Tolls 《丧钟为谁而鸣》 )和收税的意思。文中的highway指高速公路，Highway toll fees指高速公路收费，loan指贷款。
