Overhead Bridge Limiters, also known as gantry bridges or gantry spans, have been causing significant accidents and losses in recent years, with bridge collapses occurring frequently. The reasons for these catastrophic events are often attributed to overweight and over-limit issues, poor bridge design and construction, as well as inadequate supervision and maintenance.
The original role and function of overhead bridge barriers have undergone drastic changes and expansions. Their basic function has extended from protecting bridges and tunnels to safeguarding roads. The quality of overhead bridge barriers has rapidly upgraded from small and light to large and heavy. Moreover, in addition to the unified installation by bridge management authorities, there has been an emergence of private and excessive installations by social units. Overhead bridge barriers are not a magic charm for preventing overloaded vehicles from entering bridges, nor are they a one-size-fits-all solution. How to reasonably set up and manage these barriers is a matter that deserves in-depth consideration by relevant departments.
Highway LED display gantry, playing a significant role in height restriction, road guidance, warnings, and traffic condition reports.
Currently, China has not yet issued unified regulations for the establishment and management of overpasses on various roadways and bridges in cities. The relevant departmental standards are also relatively outdated, such as the "Technical Specification for Urban Road Design" (CJJ37-2012) approved and implemented by the Ministry of Housing and Urban-Rural Development of the People's Republic of China on May 1, 2012. This specification clearly stipulates the road clearance, with the minimum clear height for various motor vehicles on the driving lanes being 4.5 meters. For roads accommodating trolleybuses, tramways, double-decker coaches, and other special vehicles, the minimum clear height should meet the requirements for vehicle passage.
