Overhead bridge barriers, also known as gantry bridges or beam bridges, have been involved in significant bridge collapse incidents in recent years, resulting in severe losses and alarming situations. The causes are primarily due to overloading, poor bridge design and construction, as well as inadequate supervision and maintenance.
The original role and function of overhead guardrails have undergone significant changes and expansions. Their basic function has extended from protecting bridges and tunnels to safeguarding roads. The quality of overhead guardrails has rapidly upgraded from small and light to large and heavy. Moreover, in addition to the bridge management authorities uniformly setting up overhead guardrails, there has also been a phenomenon of private and excessive installation of such guardrails by social units. Overhead guardrails 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 guardrails is a matter that deserves in-depth consideration by relevant departments.

Currently, China has not issued uniform regulations for the establishment and management of road and bridge overpasses in cities. Relevant ministry-issued standards are also relatively behind the times. For instance, the "Technical Code 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, clearly stipulates the road clearance requirements. In the vehicle lanes, the minimum net height for various motor vehicles is 4.5 meters; for roads used by trams, trolleybuses, and double-decker coaches, etc., the minimum net height should meet the requirements for vehicle passage.
