Overhead bridge barriers, also known as gantry bridges or gantry spans, have been experiencing frequent collapses in recent years, resulting in significant losses and shocking scenes. The reasons for these collapses are primarily due to overweight and over-dimensional loads, poor bridge design and construction, as well as inadequate supervision and maintenance.
The original role and function of overhead barriers have undergone a dramatic change and expansion. Their basic function has extended from protecting bridges and tunnels to protecting roads. The quality of overhead barriers has rapidly upgraded from small and light to large and heavy. Moreover, in addition to the uniform installation of overhead barriers by bridge management authorities, there has even been a phenomenon of private and excessive installation by social units. Overhead 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 barriers is a matter worthy of in-depth consideration by relevant departments.

Currently, China has yet to establish unified regulations for the setting and management of road and bridge overpasses in cities. The relevant departmental standards are also relatively outdated, such as the "Technical Code for Urban Road Design" (CJJ37-2012) approved and implemented by the Ministry of Housing and Urban-Rural Development of the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. This code explicitly stipulates the road clearance, with the minimum clear height for various vehicles on the motorway being 4.5 meters. For roads designated for trams, trolleybuses, double-decker coaches, and other special vehicles, the minimum clearance should meet the requirements for vehicle passage.
