取消高速收费，第一枪打响了！公路收费期限最长不得超过30年

Group 1 - The core point of the news is that certain highways in Sichuan, specifically Chengmian Expressway and Chengbei Exit Expressway, will become toll-free starting from September 2025, which is seen as a significant benefit for drivers [1][4][9] - The announcement indicates that the Chengmian Expressway will stop charging tolls at 24:00 on September 4, 2025, and the Chengbei Exit Expressway will stop charging at 24:00 on September 17, 2025 [1][4] - The trend of eliminating tolls on older highways is not unique to Sichuan, as other regions like Guangzhou and Shanghai have also made similar moves, indicating a broader national trend towards toll-free highways [3][4] Group 2 - The financial implications of toll-free highways are significant, as popular routes can generate substantial revenue; for example, the Hujia Expressway earned over 200 million yuan annually from tolls, quickly recouping its construction costs [5][9] - However, not all highways are profitable, especially in remote areas where traffic is low, leading to challenges in maintenance and debt repayment [7][9] - The government faces multiple challenges in transitioning to a toll-free system, including funding for highway maintenance, the need for new road construction, and the impact of increasing electric vehicles on traditional funding sources [9][11]
