Overhead Bridge Restrictions, also known as gantry bridges or beam bridges, have been increasingly prevalent in recent years. Major bridge collapse incidents have occurred frequently, resulting in significant damage...
Severe losses, shocking to the eyes. The reasons are mainly due to overweight and over-limit issues, bridge design and construction, as well as bridge 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 authorities, there is even a phenomenon of private and excessive installation of overhead bridge barriers by social units. Overhead bridge barriers are not a magic charm to control overloaded vehicles from entering bridges, nor are they a one-size-fits-all solution. How to reasonably set up and manage overhead bridge barriers is a matter that deserves in-depth consideration by relevant departments.

Currently, China has not yet issued regulations that can be uniformly referenced for the installation and management of road and bridge overpasses in cities. The relevant ministry-issued standards are also relatively outdated. For instance, 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, has specific provisions for road clearances. In the motorized lanes, the minimum clear height for various motor vehicles is 4.5 meters. For roads accommodating trolleybuses, tramways, double-decker buses, and other special vehicles, the minimum clear height should meet the requirements for vehicle passage.
