Are there service areas on national highways?

[VanHannah]

There are service areas on national highways, but they are relatively fewer. Here is relevant information: 1. Adding service areas along ordinary national and provincial trunk highways is part of the unified planning and deployment by the Ministry of Transport; 2. Shandong Province has included 24 ordinary national/provincial highway service facilities in the first batch of national pilot projects, comprising 19 service areas and 5 parking areas. Expressway service areas refer to dedicated rest stops for passengers and drivers, which should provide parking lots, public toilets, gas stations, vehicle repair shops, dining facilities, and convenience stores, with an average spacing of approximately 50 kilometers. The construction scale of service areas should accommodate future traffic growth.
