走高速要交费，早已是咱们国人的共识。但你知道吗？现在已经有地方的高速开始免费了。 成都的成绵高速、城北出口高速即将停收，广州的东南西北环高速早就全线免费，深圳更是在2014年就花27亿回购梅关高速，提前13年让它免费通行。 广州北环高速停收时，每年要少赚几个亿，已经算很有魄力了；深圳更狠，提前13年回购梅关高速，等于放弃了五六十亿的收入，这种案例至今也只有一 个。 反观有些地方，明明高速到期该停收了，却搞"改扩建"。哪怕只是加几棵树、拓宽一点，就能重新核算收费年限，再收30年，贪婪的心思藏都藏不住。 更让人意外的是，不光高速在收费，连原本该免费的国道也开始设收费站了。最近五年，全国至少有30多个国道一级公路新增了收费站，山东、湖北、陕西 等地都有，有的收三五年，有的直接定30年。 这些城市的动作，让不少人好奇：高速免费为啥这么难？为啥有的城市能做到，北京却连五环内5块钱的收费站都不肯撤？ 今天就把高速收费的事儿掰扯清楚，看看免费高速的潮流啥时候能轮到你家。 首先得明白，高速收费不是"想收就收"，背后有历史原因，但也藏着利益的博弈。上世纪80年代末，咱们国家没钱修高速，就搞了"贷款修路、收费还贷"的 政策。谁出 ...

Core Points - Sichuan has initiated a significant move by making the Chengmian Expressway and Chengbei Exit Expressway toll-free, marking a notable shift towards free highways in the western region of China [1][5][12] - The decision to eliminate tolls is attributed to the expiration of the toll collection period, as highways in China have a maximum operational toll period of 30 years for commercial roads and 20 years for government-funded roads [5][8] - The move has been positively received by local drivers, with many expressing their excitement over the newfound savings on tolls [3][10] Summary by Sections - **Importance of the Highways**: Chengmian Expressway serves as a vital route connecting Chengdu to Mianyang, heavily utilized by both commercial and personal vehicles, while the Chengbei Exit Expressway is crucial for residents commuting to the city or traveling towards Shaanxi [3][5] - **Financial Implications**: The financial sustainability of toll-free highways varies across regions; while some expressways in economically prosperous areas generate substantial revenue, many in the central and western regions operate at a loss and rely on government subsidies [7][8] - **Future of Highway Tolling**: The trend towards free highways is seen as a necessary evolution, with the expectation that more cities will follow Sichuan's lead. However, the transition will require careful financial planning to ensure that maintenance and operational costs are covered [10][12]
