Sansi Lighted Up A 1386-Meter Canyon Suspension Bridge



As one of the major arteries of southwest traffic, the Huaping-Lijiang Expressway is an important part of the national expressway network, which is of great significance to promoting the economic development of Yunnan Province.The Jinshajiang Suspension Bridge is located in the mountainous gorge on this section of the road, and its bridge width-to-span ratio has set new records in many aspects, making a miraculous thoroughfare between the cliffs.


Sansi provided professional lighting system solutions for this ultra-long-span suspension bridge, including huge amounts of lighting fixtures and systems such as guardrail lights, wall lights, and floodlights. In particular, the low-position LED guardrail lights independently developed by Sansi solves the lighting problem caused by the steel beam structure of the bridge. More than 4000 sets of low-position lights are integrated with the guardrails. While ensuring high-quality lighting, Sansi also takes into account the requirements of simple installation, simplicity and beauty, which has won the high recognition of the bridge management department.
