高速公路带来的社会经济效益已为事实所证明。社会各界对要发展高速公路已不存异议,但对要建多少高速公路,现有高速公路规模是否已经够了,制定出台的发展目标是否偏高,还存在一些疑问。本文试图回答这些问题。 The social and economic benefits brought by the expressway have been proved by the facts. There is no disagreement on the development of the expressway from all walks of life.

This article attempts to answer these questions.
