​HKU MiCLab has leveraged its proprietary 3D Swept Path Analysis (SPA) technology to support the Civil Engineering and Development Department (CEDD) in achieving safe and efficient transport of over-dimensional prefabricated footbridge segments for the Fanling Bypass project.

​

Supported by the Smart Traffic Fund (PSRI/69/2306/RA), MiCLab developed the 3D SPA tool to optimize the planning of oversized cargo transport operations, such as prefabricated modules in construction and heavy machinery. It is expected to reduce transportation risks and enhance approval efficiency by over 40%.

​

The project features a distinctive circular footbridge with a maximum width of 7.8 meters, exceeding standard dual-lane road widths. To maximize construction efficiency, the engineering team pioneered an "in-factory prefabrication + modular transport" strategy. Pre-assembled bridge modules were manufactured at mainland factories, shipped to Hong Kong by sea, and transported via an innovative 12-meter tilted modular configuration to navigate the 34-kilometer complex land route.

​

Faced with the challenge of transporting the widest footbridge modules in Hong Kong’s public road history, MiCLab collaborated closely with the CEDD and the Lands Department. Utilizing geospatial data collected by the Lands Department’s mobile mapping system, MiCLab applied its 3D SPA to conduct high-accuracy and immersive simulations of the transport route. This innovative technology identified and mitigated potential risks, significantly boosting confidence among regulators, including the Transport Department and the Police Force, thereby accelerating approval processes. Through government-industry-university close coordination, all modules of the 370-meter-long footbridge were successfully transported in 12 overnight operations.​​​​​​
