“收費公路”英語怎麼說

摘要：全國收費公路專項清理第一階段摸底調查已於8月底結束，按照要求，各地摸底情況近期將對外公佈。截至昨日，至少已有北京、上海、山東等12省份公佈了收費公路摸底調查結果。你知道怎麼用英語表達嗎?

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).

週六，北京交通委稱北京收費公路仍然負債嚴重，高速公路收費的三分之一都用來償還建設公路的貸款利息。北京交通監管機構—北京市交通委在其網站上稱，截止2010年底，全市共有收費公路816公里，債務餘額高達440億元。

　【講解】文中的toll roads即指收費公路，toll在這裏指通行費，toll作名詞時還有傷亡人數(death toll)和鐘聲的意思，toll還可以作動詞，有敲鐘(For Whom The Bell Tolls 《喪鐘爲誰而鳴》 )和收稅的意思。文中的highway指高速公路，Highway toll fees指高速公路收費，loan指貸款。
